Book excerpt: More foods are now packaged in containers designed for direct cooking or heating, which encourages movement of substances into the foods. Indirect Food Additives and Polymers: Migration and Toxicology is an impressive review of basic regulatory, toxicological, and other scientific information necessary to identify, characterize, measure, and predict the hazards of nearly 2,000 of the plastic-like materials employed in packaging and identified by the FDA as indirect food additives. It presents the data underlying federal regulations, previously unavailable in one volume, and is a convenient resource for anyone working in the large number of related disciplines.
