Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad 5 International Action Over the past 30 years, international trade, outsourcing, and improvements in telecommunication have created a more unified world economic system. This system presents new challenges. No country can rely solely on its own national regulatory authority to ensure food and medical product safety. Regulators today depend on their counterparts abroad in ways that no one could have foreseen in the 19th and early 20th centuries when many food and medical product regulatory systems were designed. Changes in trade and manufacturing patterns call for changes in the ways countries work together for safety. The committee recommends that governments, industries, and academia work more consciously across borders to their mutual benefit. This chapter recommends specific areas for international cooperation, namely: increasing international investments in regulatory systems; encouraging open dialogue among government, industry, and academia; working toward voluntary sharing of inspection reports; and supporting surveillance. INCREASING INTERNATIONAL INVESTMENTS There is a common ground where food and medical product safety, global health, international trade, and development are mutually reinforcing (Henson and Jaffee, 2008; Horton and Wright, 2008; Maertens and Swinnen, 2009). Chapter 4 describes the nexus of these topics, and this report suggests actions that will advance their common goals. Both the health and the economy in developing countries would benefit from investments in their regulatory systems; these investments are also tools for international

Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad trade. Intergovernmental institutions and international donor agencies have not yet recognized this or, if they have, their investments do not reflect it. Recommendation 5-1: In the next 3 to 5 years, international and intergovernmental organizations should invest more in strengthening the capacity of regulatory systems in developing countries. The United States should work with interested countries to add it to the G20 agenda. Investments in international food and medical product safety should be a significant and explicitly tracked priority at development banks, regional economic communities, and public health institutions. International organizations should provide assistance to achieve meaningful participation of developing country representatives at international harmonization and standardization meetings. One measure of this recommendation will be the extent to which the 2012 Group of 20 (G20) meeting in Mexico includes food and medical product safety on its agenda. The amount of discussion at the Mexico meeting and at subsequent G20 meetings will be a further measure. Actions from the G20 meeting and increased allocations to regulatory systems can also measure this recommendation. An increased attendance of scientists from developing countries at standard setting meetings and the development of programs that improve their participation would also be measures. Putting this topic on the agenda at the 2012 G20 meeting can be accomplished in the next year. Increasing investments in building regulatory systems and tracking these investments could take longer; this should begin in the next 3 to 5 years and continue. Advancing Safety Standards Through Trade Safety standards serve many purposes. They protect health by reducing the likelihood of harmful products circulating in the market. They also facilitate trade: countries with disparate product safety regulations use common standards in the international market (Maertens and Swinnen, 2009). International or harmonized standards and certification regimes are useful to both exporters and importers. They lend predictability to regulatory decisions and protect against accusations of arbitrary barriers to trade. International standards also simplify the requirements for export to multiple markets. The committee commends the Global Food Safety Fund, supported by Waters Corporation, Mars Inc., and the U.S. Agency for International Development (USAID), for its pilot training program in the Asia Pacific Economic Cooperation (APEC) countries. This program draws on funding and expertise from government and the private sector to establish training programs and improve testing in developing countries (Goetz, 2011).

Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad Complying with international safety standards can be expensive, especially when starting from scratch. However, once a producer has invested in meeting standards for one market, his or her marginal compliance costs decrease as the size of the market increases. These economies of scale could drive better safety standards in emerging economies (Henson and Jaffee, 2008; Horton and Wright, 2008). International trade negotiations and agreements such as the World Trade Organization (WTO) Agreements on Application of Sanitary and Phytosanitary Measures (SPS) and the Technical Barriers to Trade (TBT) promote harmonization and encourage the use of international, science-based food and drug standards.1,2 Developing countries can obtain guidance on compliance from Codex, the World Organization for Animal Health, the World Health Organization (WHO), and other international organizations. Ideally, low- and middle-income countries would use international standards in their own regulatory systems. This would protect health in places where foodborne disease and substandard drugs kill many. It would also promote the competitiveness of exports from low- and middle-income countries in hard-currency markets (Henson, 2003; Maertens and Swinnen, 2009; World Bank, 2005). Failure to comply with food and drug safety standards can lead to product border detentions, import bans, and contractual penalties. The costs of failing to meet standards are substantial, especially for producers in low- and middle-income countries (Henson, 2003). Therefore, even developing countries with little public health infrastructure have reason to invest in oversight of food and drug exports. The prospect of increased trade can motivate developing countries to invest in safety standards and regulatory oversight. Demonstrated ability to adhere to standards can improve their ability to export to tightly regulated markets (Maertens and Swinnen, 2009). These improvements in turn encourage foreign direct investment in local food and drug processing, exporting, and retailing (Henson and Jaffee, 2008). This arrangement can have spillover benefits for local populations: they can count on safe food and medicine, and their economies thrive (Unnevehr et al., 2003). Investors and multinational companies spread the use of high standards in developing countries to reduce transaction costs in regional distribution and supply chains, and to harmonize production and processing 1 Agreement on the Application of Sanitary and Phytosanitary Measures, Apr. 15, 1994, Marrakesh Agreement Establishing the World Trade Organization, Annex 1B, THE LEGAL TEXTS: THE RESULTS OF THE URUGUAY ROUND OF MULTILATERAL TRADE NEGOTIATIONS 121 (1999), 1867 U.N.T.S. 493 (1994), art. 2, 4 2 Agreement on Technical Barriers to Trade, Apr. 15, 1994, Marrakesh Agreement Establishing the World Trade Organization, Annex 1B, THE LEGAL TEXTS: THE RESULTS OF THE URUGUAY ROUND OF MULTILATERAL TRADE NEGOTIATIONS 59 (1999), 1868 U.N.T.S. 120 (1994), art. 2.4.

Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad standards across subsidiaries (Henson and Jaffee, 2008; Maertens and Swinnen, 2009). The mechanism of this spillover benefit is complicated. The committee recognizes that many countries do support higher safety controls on exported products and neglect to implement best practices for their domestic markets. There is reason this could change, and the committee believes the changes will be more quickly realized in the medical products industry than in the food industry. Medical products are complicated to manufacture; cottage industry production of drug ingredients, while not unheard of, is rare. The spillover benefits of better product standards will take time, probably at least 10 years, and will happen at the company and industry levels and at the regulatory system level. First of all, at the company level, there are common manufacturing processes for both the export and domestic markets. The process a company goes through to meet international standards creates greater knowledge, awareness, and experience with the standards throughout the company and industry. Staff who train against international best practices also bring their skills to other firms as they progress in their careers. There is room for cross-fertilization of ideas within companies and, because of job turnover, within industries. The committee also sees room for spillover at the national level. As regulators inspect companies against domestic standards, they will be exposed to records, book-keeping, and audit reports reflecting international standards. Regulators will become better acquainted with international standards. Furthermore, regulators in low- and middle-income countries are already keen to enforce international standards; the international meetings for this study convinced the committee of this. However, lobbying forces in the domestic industry work to prevent this. The committee believes that pressure at the ministry levels of government could override the lobbying from industry and create momentum for higher domestic standards. Much of this depends on the demands people in developing countries put on their governments. Chapter 3 explains how increased prosperity in parts of Asia, Africa, and Latin America drives increased attention to food and drug safety. Middle-class consumers will pay more for safer food (Morehouse and Moriarty, 2007). Studies in the United States and Europe indicate that consumers will pay more for higher quality food (Enneking, 2004; Lusk et al., 2003). Improving the ability of producers in low- and middle-income countries to adhere to international standards is to the shared advantage of consumers around the world. As demand for animal-source foods increases and access to medicines improves in low- and middle-income countries, the interests of consumers in developed and developing countries will overlap more (Unnevehr et al., 2003). Many low- and middle-income countries have a two-tier regulatory model in which products for export are fairly well regulated, but those for

Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad domestic consumption are not (World Bank, 2006). Consumers in these countries could come to resent being subjected to lower standards. There is also invariably intermixing of domestic and export product lines. This undermines developed country regulators’ confidence in the products they import. International food and drug safety standards promote trade and global health, but the proliferation of overlapping, often inconsistent national and private standards do not. Adoption of international food standards has been slow and, in high-income countries such as the United States, poor (Roberts and Josling, 2011). The United States puts great effort into ensuring its standards are close to the Codex ones, but, because of an apparent disconnect between international and domestic priorities, these standards are often not adopted. When large, hard-currency economies disagree on standards, they undermine the efforts to enforce them in low- and middle-income countries (Horton and Wright, 2008). Inconsistent national standards impede market access and breed trade disputes, which in turn undermine developing country support for future multilateral trade agreements (Henson and Jaffee, 2008). The committee advocates for greater consistency in the use of standards on the part of the developed countries. Although the SPS Agreement allows signatories to adopt more stringent standards than Codex calls for if they have scientific reason, the committee sees this practice as unnecessarily harmful to emerging economies. For example, high-value agricultural products are a promising business for farmers in the Horn of Africa. In order to sell on the European market these farmers need to meet requirements for pesticide residues, field and pack house operations, and traceability (Okello et al., 2007). Businesses increasingly rely on private organization standards, voluntary third-party certifications, and their own safety and quality management systems to regulate their suppliers. This is not an efficient system. It increases the cost of compliance for producers and can lock small- and medium-sized holders out of the market (Maskus et al., 2005). This is a particular problem in low- and middle-income countries, where small- and medium-sized businesses dominate much of the pharmaceutical (and vastly more of the food) supply chain. Public—private partnerships can play a key role in satisfying market demands for food safety while retaining smallholders in the supply chain (Narrod et al., 2009). Priorities for Future Multilateral and International Engagement The United States should work with like-minded governments to pursue food and drug safety at intergovernmental trade, development, and global health forums. A global approach to food and drug safety would

Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad lessen claims of double standards and reflect the shared interests of developed and developing countries. Intergovernmental venues are important because food and drug regulation in one state is increasingly dependent on the adequacy of regulation in other states. Linking global health, trade, and economic development objectives can help engage a wide variety of stakeholders. The committee recognizes that many international organizations work to build food and medical product regulatory capacity around the world. Tables 2-2 and 2-3 give examples of some prominent capacity building projects in food and drug safety. Action for the Group of Twenty (G20) The G20 brings together leaders from industrialized and emerging economies to work together for global economic stability and development. The support of the G20 would do much to advance the international food and drug safety agenda. As a leaders’ summit of the largest economies in the world, the G20 has the political and economic influence to advance food and medical product safety internationally (Kharas, 2011). The G20 membership includes many important stakeholders—representatives of emerging manufacturing economies including India, China, South Africa, Mexico, Thailand, and Brazil, as well as the developed countries in a position to offer technical assistance like the United States and members of the European Union (G20, 2011). The G20 countries need to commit to improving regulatory systems; without their support, change is unlikely (Drezner, 2007). If food and medical product regulatory systems received prominent attention at a G20 meeting it could spur investment from other donors, intergovernmental institutions, and national governments. Global food and drug safety is well suited for the G20 agenda. The G20 development priorities include international trade, food security, investment, and job creation in low- and middle-income countries (G20, 2010). The multi-year G20 development agenda already includes many programs that promote food and medical product safety: identifying practical ways to support trade integration; harnessing agriculture to reduce poverty; increasing private-sector participation in development; and promoting small business’ access to international markets (G20, 2010). The G20 has recognized international development as integral to its “mandate of global economic cooperation” and a critical component of the G20’s goal is “strengthening the relationships among high-, middle-, and low-income countries” (G20, 2010, p. 1). The G20 development priorities include matters dependent on improved food and drug safety: international trade, food security, and investment and job creation in low- and middle-income countries (G20, 2010). The G20 should take food and drug safety seriously because it has significant implications for public health, trade, and economic development

Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad in G20 countries. The means to address this issue—improved regulatory cooperation, information sharing, and adoption of international standards—are also all areas in which consensus among G20 countries is possible despite the diversity of their economies. This should make it easier for G20 members to act (Kharas, 2011). Mexico will host the 2012 G20 meeting. As a middle-income country with a vigorous export economy, Mexico would be an ideal country to lead an initiative on global food and drug safety. This initiative might include increasing information sharing among stringent regulatory authorities to reduce redundant audits. Another valuable action would be enhancing the meaningful participation of developing country scientists in international standard setting. They might also emphasize supporting small- and medium-sized developing country producers in complying with international standards. The United States, working with other G20 member states, should encourage and support Mexico before, during, and after the 2012 G20 meeting. Actions for the WTO, Development Banks, and Regional Economic Institutions The development banks, regional economic communities, and public health institutions need to invest more in food and medical product safety; this includes investments in the systems and processes that ensure product safety. A 2005 World Bank report stressed that capacity building, especially as it relates to product safety standards, should avoid isolated interventions and work to increase broader market competitiveness (World Bank, 2005). The World Bank is gradually increasing such loans. In 2005 it lent Colombia $30 million to improve the competitiveness of its meat and milk exports (Nuthall, 2005), and a 2010 program invested $100 million in China’s adherence to good agricultural practices (World Bank, 2010). Some of the regional banks are working on the same issues. A 2009 $95 million Asian Development Bank loan to Vietnam aims to improve the quality of commercial agriculture (ADB, 2009). These loans are a step in the right direction, but they need to reach more countries. Standard Setting As Chapter 3 discusses, scientists from developing countries are often not prepared to make meaningful contributions at international standard setting meetings. Their countries clearly suffer as a result, becoming standard-takers, not equal standard-setters. Their silence also undermines the legitimacy of the standard setting process. And, in the end, they are unable to comply with the standards produced (Horton and Wright, 2008).

Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad The committee recognized that the three international food standard setting organizations recognized by the WTO—Codex Alimentarius, the International Plant Protection Convention (IPPC), and the World Organization for Animal Health (OIE)—are valuable sources of information and training for regulators in developing countries. Nevertheless, more must be done to mobilize resources and provide technical support that can encourage the participation of developing countries. The International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) should likewise do more to encourage meaningful engagement by low- and middle-income countries, consistent with trends in the global production and consumption of medicines. These organizations should work closely with regional economic and public health institutions such as APEC, the Pan American Health Organization, the Association of Southeast Asian Nations, the American Institute for Cooperation on Agriculture, and the African Union Interafrican Bureau for Animal Resources to engage low- and middle-income countries. ENCOURAGING OPEN DIALOGUE AMONG GOVERNMENT, INDUSTRY, AND ACADEMIA IN EMERGING ECONOMIES A robust regulatory system depends on input from industry and academia; government simply cannot shoulder the burden alone. Most developed country regulators describe their system as a stool supported by three legs: industry, government, and academia. The shared responsibility makes for a stronger system with much wider ownership. In low- and middle-income countries, especially in Asia and Africa, it is not so. It is important for consumer groups and industry to have a chance to comment on regulations before they are made. It is also important that all parties should be able to modify laws if they have scientific evidence to support a change. Recommendation 5-2: In emerging economies, national regulatory authorities, regulated industry, and industry associations should engage in open and regular dialogue to exchange scientific and technical information before policies are written and after they are implemented. Starting in the next 3 to 5 years, these regulatory authorities should identify third parties, such as science academies, to convene the three pillars of a regulatory system—government, industry, and academia—in ongoing discussion to advance regulatory science, policy, and training. The number of meetings among industry, academia, and government regulators in low- and middle-income countries will be one measure of this recommendation. Another important measure will be the policy outcomes
OCR for page 173
Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad of the meetings. However, in measuring the impact of open dialogue the process is as important, if not more important, than the outcome. Openness in involving all stakeholders and actively seeking neutral forums for discourse are the most important outcomes of this recommendation. Communication and Transparency Lack of communication and transparency are major gaps found within and between regulatory systems around the world (IOM, 2009; IUF, 2009). A lack of openness aggravates the problems, as does poor communication between industry and consumer groups. It is therefore not surprising that there are problems with both transparency and communication across borders. Regulatory systems in low- and middle-income countries have this problem, and similar communication gaps exist in the United States. However, the United States has public reporting requirements, external advisory boards, independent national association meetings, and study panels, such as those convened by the Institute of Medicine, that provide avenues for communication. This kind of open dialogue is essential for progress. These opportunities for open dialogue are often lacking in developing countries. In low- and middle-income countries, the line between scientific and policy decisions is often blurred. Both often require political clearance at the highest government levels. This hampers efforts to promptly transmit the technical data crucial for assuring product safety. In some countries, so-called independent organizations act as go-betweens for government and industry, but in reality their independence is nominal. In other cases, the lack of suitable venues or personnel to transmit technical data, such as the testing requirements for a new regulation, holds back communication. This gap is especially evident as one goes from national to state and provincial authorities. This problem is complicated by the dearth of scientific staff at the more local levels. Similarly, the regulated industry has little ability to provide input into new regulations or get technical guidance on compliance. Academia can help bridge regulatory agencies and industry, but its involvement is generally minimal. Avenues to More Effective Dialogue There are examples in North America, Europe, and Australia where the three independent pillars of well functioning stringent regulatory systems (government, industry, and academia) are brought together to discuss issues of mutual concern (Australian Government, 2011; Global Harmonization Initiative, 2011; Health Canada, 2009; IOM, 2011). For example, the U.S. Department of Agriculture (USDA) and the U.S. Food and Drug Administration (FDA) worked with the Department of Homeland Security and the
OCR for page 174
Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad Federal Bureau of Investigation to jointly engage states and private industry in food defense (USDA, 2005). These partnerships lead to better protection of the food supply from farm to table. These partnerships present a number of opportunities. First, stakeholders can discuss technical issues related to standard setting, testing, and approaches to implementation. Second, they provide a mechanism for information dissemination, especially on adopting new regulations. Third, international experts could teach satellite courses to educate provincial or municipal staff on implementing regulations from the national regulatory authority. These recommendations are generally concerned with opportunities for training and training trainers, and training sessions are excellent venues for open dialogue. In emerging economies, existing regional bodies will be an important venues for communication among neighboring countries facing similar problems. The FDA could help facilitate such meetings by sending its overseas staff when appropriate opportunities arise. Convening Three Pillars of a Regulatory System Professional associations and academic institutions are often good places to bring together stakeholders for balanced and open dialogue on regulatory policy (ASM, 2011; IFT, 2011). Although such venues cannot and should not assume decision-making functions of government agencies, they do open lines of communication among regulators, sister agencies, academic experts, and multiple levels of regulated industry. There are notable glimmers of improving communication in some places. In November 2011, the Indian food regulatory authority took public input from food industry associations in designing its product recall plan (FSSAI, 2011). Even in this case, however, academia was notably uninvolved. This is a problem as gaps in basic and regulatory sciences prevent a regulatory authority from doing its job (Mattes et al., 2010). Regulatory science is a new field (Gundersen, 2001). It is multidisciplinary and includes elements of basic science, epidemiology, statistics, social science, business management, public policy, and communication. A field of such breadth needs instructors with practical experience. The emergence of such cross-cutting disciplines requires collaboration between universities, industry, and government. The first step to advance regulatory science in emerging economies is to bring these stakeholders together. National Science Academies As noted previously, a number of organizations have at various times convened government, industry, and academia on product safety. Science
OCR for page 175
Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad academies are uniquely positioned to serve in this area. Science academies have expertise to draw from among their members, who are elected by their peers. Election to a national academy is an honor. It is also a chance for elite scientists to serve their country, and it gives countries a trusted and independent advisory body. Science academies are, in many countries, a neutral space that can bring together stakeholders from various disciplines. Their focus on evidence-based decision making provides the neutral setting needed to bring together academia, government, and industry. Public Health Forums According to the Institute of Medicine’s report on the Future of Public Health, “[p]ublic health is what we, as a society, do collectively to assure the conditions for people to be healthy” (IOM, 1988, p. 20). Public health agencies work at the intersection of science, government, business, and civil society. They oversee the implementation of health policies and regulations. However, state health agencies in many developing countries lack the infrastructure to carry out standard public health functions such as surveillance (Mok et al., 2010). The Bill and Melinda Gates Foundation funded the International Association of National Public Health Institutes in 2006 to build public health institutes in less-developed countries (IANPHI, 2011b). A particular focus of its work has been on improving public health functions like disease surveillance, outbreak investigation and response, and operations research (IANPHI, 2011a). The Association of Food and Drug Officials (AFDO), established in 1896, works toward public health safety and consumer protection in regulatory areas concerned with food, drugs, devices, cosmetics, and consumer products (AFDO, 2010). Along with promoting education and dialogue among government, industry, and consumers, AFDO also provides “guidance and training programs for regulatory officials and the regulated industry, to promote nationally and internationally uniform inspections, analyses, interpretations and investigations” (AFDO, 2010). Other international organizations such as the WHO, the Food and Agriculture Organization of the United Nations (FAO), and WTO have provided similar forums and support for discussions on food and medical product regulation (FAO/WHO, 2005; GIFSL, 2010; WHO, 2011; WTO, 2011). In addition, the International Biopharmaceutical Association brings together biopharmaceutical and clinical research institutions and organizations from different countries. All of these organizations could convene and educate students, possibly through their online discussion groups.

Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad of surveillance tools, protocols for foodborne disease surveillance and post market surveillance of medical products, and training of national regulatory authority staff and national experts. The most direct measure of this recommendation will be the number of programs these agencies initiate to improve foodborne disease and postmarket surveillance systems in developing countries. Over time, a change in the number of surveillance staff at regulatory agencies in low- and middle-income countries will be another measure of this recommendation. In addition to measuring these process indicators, the functioning of the surveillance tools developed will be measured using sensitivity and specificity criteria specific to each tool. The scientists developing these tools will need to articulate the minimum threshold at which the tool is functioning properly. Building a cadre of trained epidemiologists will take time. This important step of strengthening surveillance systems may take 10 years or longer to develop. In the next 3 years, USAID, FDA, CDC, and USDA can work with their host country counterparts to develop and strengthen manageable systems for postmarket surveillance of medical products. Developing a foodborne disease surveillance system will require improvements in laboratory infrastructure and will therefore take longer, but the committee believes meaningful improvements, such as the expansion of the CDC PulseNet program, can begin in the next 5 years. Surveillance Tools The most frequent approach to postmarket surveillance of medical products in developing countries is spontaneous or passive reporting by health workers. Spontaneous reporting systems have important limitations. Because they rely on overworked doctors and nurses or, even worse, on patient initiative, spontaneous reporting is synonymous with underreporting. Spontaneous reporting systems can generate useful data and give early signals of medical product safety problems, but in the poorest countries even passive reporting systems are not functional (Kuemmerle et al., 2011). Active surveillance complements spontaneous reporting systems. Active surveillance involves methodically searching for exposures of interest or adverse events at sentinel surveillance sites. These sites, sometimes hospitals or clinics, collect enough data to allow analysts to calculate event rates with an accurate denominator. Sentinel surveillance sites at hospitals and health centers in developing countries need to be improved. These improvements should accompany the development of active surveillance when necessary. For example, drug regulators can engage active surveillance systems after passive event reporting or sentinel sites identify a signal. The WHO and

Global Fund have proposed the essential elements of a national pharmacovigilance system (Xueref, 2010). Trainers should work to align their technical support to these systems. Independent laboratories are also essential for functional surveillance systems. Food safety surveillance in particular depends on laboratories for molecular subtyping of pathogens. This is challenging in developing countries, and the committee sees expanding laboratory capacity as a key piece of the technical support U.S. and international organizations should give. The CDC’s PulseNet program has given valuable technical support
OCR for page 184
Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad in developing clinical, reference, and food safety laboratories in Asia and Latin America (Swaminathan et al., 2006). The committee encourages this expansion of PulseNet over the next 5 years and believes every part of the world could benefit from the PulseNet system. Fortunately, information technology has created a wealth of surveillance tools more easily adapted to middle-income countries. These methods are often described as event-based. That is, they rely on patterns of events: Google searches on symptom clusters, news reports, and discussion threads on blogs and in Internet chat rooms. Figure 5-1 describes how these events can be alerts of an epidemic that is still in the early stages. Twitter and other Internet-based surveillance tools have been useful in tracking the incidence of dengue fever in Brazil (Gomide et al., 2011). In the poorest countries, the lack of Internet access will prevent the reliable use of Internet-based surveillance, but the conceptually similar mobile phone surveillance shows promise (Breiman et al., 2008). The CDC’s BioSense system is an example of a surveillance tool that uses Internet technology to create an online surveillance community (Box 5-1).

Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad BOX 5-1 The BioSense Redesign Following the anthrax attacks of 2001, the U.S. government recognized the need for a more informed and better equipped public health sector to deal with potential and actual bioterrorism threats (SEMP, 2008). In 2002, Congress passed the Public Health Security and Bioterrorism Preparedness and Response Act (FDA, 2002). This act mandated the formation of BioSense, a program housed in the CDC. BioSense is a data collection and analysis program that helps public health officials throughout the United States plan for, detect, and respond to disease outbreaks that may be related to bioterrorism. BioSense is used for both prevention and response, making it a multifaceted tool for the preservation and advancement of national health (CDC, 2012). After operating for several years as a program focused primarily on bioterror threat detection, in 2010 the CDC began redesigning BioSense to better meet the needs of the public health sector (CDC, 2012). Some users objected to BioSense’s narrow focus and insufficient integration with other, similar programs already in use (RTI International, 2011). Guided by the suggestions of public health officials at municipal, state, and national levels, the CDC restructured BioSense to respond to a wider range of health threats. This revamped program, BioSense 2.0, facilitates collaboration within and between the levels of the public health infrastructure, and provides users with the information, analysis, and tools they need to best respond to health threats (BioSense Redesign, 2011; CDC, 2012). In essence, BioSense 2.0 creates a “public health surveillance community” comprised of public health professionals across disciplines, borders, and organizations (BioSense Redesign, 2011). The redesign project will conclude in June 2013 (RTI International, 2011). The CDC solicited input from a range of stakeholders during the BioSense redesign. A key element of this mission was the BioSense Redesign Collaboration Site, a website that solicited suggestions and asked for feedback on the project’s process (CDC, 2012). Through the website, all stakeholders were involved in the work, and their needs were incorporated into the BioSense revisions (RTI International, 2011). Foodborne disease lends itself to event-based surveillance. The Global Public Health Information Network relies on information from all pertinent news streams. This web-mining surveillance system was instrumental in containing SARS (Brownstein et al., 2009; Keller et al., 2009). Box 5-2 describes how the state of North Carolina uses an early warning system that integrates many types of signals for better food safety. The committee sees web-mining and event-based surveillance as potentially valuable tools for developing country regulators and believes all technical support should draw on this valuable new technology.

Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad BOX 5-2 North Carolina Foodborne Events Data Integration and Analysis Tool Researchers from the University of North Carolina’s Center for Logistics and Digital Strategy at the Kenan-Flagler Business School and the North Carolina Center for Public Health Preparedness in the Gillings School of Global Public Health have developed the North Carolina Foodborne Events Data Integration and Analysis (NCFEDA) tool to bridge gaps in North Carolina’s food safety system (Greis et al., 2011). The public and private sectors and consumers must all work together for food safety. There are information delays in a standard food surveillance system that can allow months to pass between the time of suspected contamination and the removal of affected products from grocery shelves. New, more timely, and more informative data sources can reduce the latent time between contamination and removal. NCFEDA reduces these latencies by making real-time information—from consumer complaints and hospital emergency room visits to social media, FDA recall information, and private-sector data—available to public health officials (Greis et al., 2011). Public health officials in North Carolina collaborated with Kenan-Flager School faculty in designing the NCFEDA tool. The tool integrates four essential capabilities that contribute to improved situational awareness. First, it integrates data from many different types of signals, such as consumer complaints and emergency room visits. It also relies on analytical tools that help make connections across these signals to better recognize disease or contamination patterns. The tool includes a visualization piece that allows mapping and other graphic data display. Finally, the tool works in real time; all stakeholders work together on a coordinated response (Greis et al., 2011). New information systems like NCFEDA can help assure better food safety and minimize the impact of food contamination events—especially for products that originate abroad. NCFEDA is a first step toward integrating a diverse set of stakeholders across North Carolina food safety systems. NCFEDA aligns with current national strategic plans for food safety, such as those outlined in the Food Safety Modernization Act. Other states and countries can use this system as a model. The committee believes that Internet-based surveillance tools might be useful in emerging economies with reasonably sophisticated technology infrastructures, such as China, India, Brazil, South Africa, Mexico, and Thailand. In less-developed countries, mobile phone technology might be used to the same end: building a novel foodborne disease and drug postmarket surveillance system.

Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad Surveillance Experts Web-mining is a promising piece of surveillance development in low- and middle-income countries, but it is not the only remedy the committee suggests. In an interview with Nature, the head of animal health at the French food safety agency cautioned against seeing Internet-based surveillance systems as an alternative to building a cadre of local epidemiologists (Butler, 2006). In the same article, Peter Roeder, a consultant with the FAO, explained, “No amount of setting international guidelines and publishing global action plans is going to help when you have an organization within the country that doesn’t know what to do” (Butler, 2006, p. 6). The committee agrees that training in-country staff in epidemiology and modern surveillance methods should be central to any and all surveillance programs. Similarly, building modern surveillance systems will include building a culture of reporting adverse effects among health workers and advertising the proper pathways for reporting. CONCLUSIONS The committee’s strategy for building regulatory systems in developing countries emphasizes international cooperation. The unified world market has united countries in many positive ways, but has also introduced new liabilities. No country’s regulatory authority can vouch for the safety of all foods and medical products in its market. The committee identified five areas where stakeholders around the world could act to improve food and medical product safety. First, the development banks, regional economic communities, and public health institutes should ensure that scientists from the least developed countries are better prepared to participate in international standard setting. The G20 is also an excellent forum to discuss how to increase investments in regulatory systems. The United States and other G20 members should support Mexico, the 2012 G20 host, in sponsoring a global initiative on building food and medical product regulatory systems. In the next 3 to 5 years, increased investment in strengthening regulatory systems capacity should be explicitly tracked at international organizations. The committee was struck by the isolation that many developing country regulators work in. They lack the involved support of industry and academia. National regulatory authorities in emerging economies should work to change this in the next 3 to 5 years and foster an open discussion on science and policy with all stakeholders. To this end, they may need to ask their national science academies to convene a stakeholder meeting. More open communication about policy will benefit all parties, but the changes should not stop there. Stringent regulatory authorities should immediately

Ensuring Safe Foods and Medical Products Through Stronger Regulatory Systems Abroad work toward sharing inspection reports; they should also coordinate their inspections in emerging economies and conduct joint inspections when possible. This collaboration will encourage cross-fertilization of ideas and, more importantly, will prevent duplicating inspections, something nobody can afford. In the next decade, they could work toward a system of mutual recognition of inspection reports, a system developing countries might also join. Industry also has a wealth of information in its internal inspection reports. In the next 3 years, industry associations should develop ways to share this information that are acceptable to their members. Finally, U.S. agencies and multilaterals with appropriate expertise should support surveillance systems in developing countries. Without reliable data on postmarket surveillance of medical products and foodborne disease, risk assessment is meaningless, and risk assessment is the cornerstone of any modern regulatory agency. In the next 3 years, it will be possible to develop a system for the postmarket surveillance of medical products, and the expansion of the CDC’s PulseNet program to more developing countries can start in 5 years. Over the next decade, the training of a cadre of developing country epidemiologists can complement this surveillance development. REFERENCES ADB (Asian Development Bank). 2009.
