Improved materials such as metal and plastic foils and container linings and coatings have resulted in more convenient food packages. Improved methods of transportation make possible the safe and rapid distribution of perishable foods to our expanding urban population centers.

Contrast the primitive problems of food adulteration with those facing the modern food and drug scientist. He must now contend with such problems as the radioactive contamination of food crops by fall-out; the bacteriology of frozen precooked foods; organic pesticide residues in food crops, milk, and meat; the presence in foods of possibly carcinogenic food additives.

However, it became obsolete with the advent of the photoelectric recording instruments. Nowadays, the scientist watches while the magic pen draws accurate spectral curves, not only in the visible region, but also in the heretofore unused ultraviolet and infrared regions of the spectrum.

From page 60... ...
During the past several years, we have examined about 6000 samples of about 50 different foods by a count of the "total beta radiation" of the ashed samples. Large-scale nuclear weapons testing ceased in October 1958, and recent analyses by the total beta method indicated a general decline in the total radioactivity of foods.

In some cases, for example, food additives and pesticide chemicals, we make the rules largely on our review and evaluation of extensive scientific data presented to us in support of specific proposals. These rules are formally announced in the Federal Register.

From page 62... ...
We are firmly convinced that sound effective administration and enforcement of the Food, Drug, and Cosmetic Act in this area of pesticide chemicals, food additives, and color additives is not possible without an accompanying strong scientific research program directed and conducted by top-flight scientists who are equipped with proper facilities including the more modern instrumentation. It has been gratifying to us to note the increasing recognition by the Congress that these needs are paramount.
