This report represents the conclusions of a Joint FAO/WHO Expert Committee convened to evaluate the safety of various food additives and contaminants with a view to recommending Acceptable Daily Intakes (ADIs) and tolerable intakes respectively and to prepare specifications for the identity and purity of food additives. The first part of the report contains a general discussion of the principles governing the toxicological evaluation of food additives (including flavouring agents) and contaminants assessments of intake and the establishment and revision of specifications of food additives. A summary follows of the Committee's evaluations of toxicological and intake data on various specific food additives (diacetyltartaric and fatty acid esters of glycerol quillaia extracts invertase from Saccharomyces cerevisiae ß-carotene from Blakeslea trispora curcumin phosphates diphosphates and polyphosphates hydrogenated poly-1-decene natamycin D-tagatose carrageenan processed Eucheuma seaweed curdlan acetylated oxidized starch a-cyclodextrin and sodium sulfate) flavouring agents and contaminants (3-chloro-1 2-propanediol 1 3-dichloro-2-propanol and a large number of polychlorinated dibenzodioxins polychlorinated dibenzofurans and coplanar polychlorinated biphenyls). Annexed to the report are tables summarizing the Committee's recommendations for ADIs of the food additives and tolerable intakes of the contaminants considered changes in the status of specifications of these food additives and specific flavouring agents and further information required or desired.

One of the striking features of our times is the increasing utilization of chemical products in different fields of human activities, as a result of the spectacular progress of chemical research. Our food supply has not been spared from this general trend, however, and chemical sub stances are being continuously incorporated in foodstuffs. Some of these substances are added to food for technological purposes such as pre serving food from bacterial deterioration (antimicrobials), protecting it from oxidative changes (antioxidants), and improving its organoleptic characteristics (sweeteners, flavors, and flavor enhancers), or texture (stabilizers, emulsifiers, colorants). These substances are generally referred to as intentional food additives. Chemical substances may also be found in food as a result of environ mental or accidental contamination. Between these two categories of chemicals, a third class occupies an intermediate position, represented by chemical products utilized to control insect or fungus pests in agri culture and ectoparasites in animal husbandry. These products are cur rently referred to as pesticides and, due to some of their properties, such as chemical stability associated with scarce hydrosolubility, they may be found as residues in or on food from plant and animal origin. In addition, certain drugs that stimulate growth for accelarating productivity in animals may also be found as residues in edible animal tissues. These substances are referred to as unintentional food additives.

This report represents the conclusions of a Joint FAO/WHO Expert Committee convened to evaluate the safety of residues of certain veterinary drugs in food and to recommend maximum levels for such residues in food. The first part of the report considers general principles regarding the evaluation of veterinary drugs within the terms of reference of JECFA, including compounds without an ADI or MRL; recommendations on principles and methods in derivation of MRLs, including a new procedure for estimating chronic dietary intakes; the use of a spreadsheet-based procedure for the statistical evaluati.

Nutritional Toxicology, Volume I is a sample result that has risen from the need for increased toxicological awareness and understanding by nutritionists and other professionals concerned with food production, utilization, and health. This book aims to collate significant information regarding nutrition-associated toxicity problems. The book is divided into 13 chapters. The first two chapters deal with a general overview of nutritional toxicology. Some of the topics discussed in this section include the nutritional effects of toxicants, xenobiotics, toxic action, and biotoxification. The following subject areas discussed include vitamin excess and toxicity; trace elements and cardiovascular disease; and factors affecting the metabolism of nonessential metals in food. The subsequent chapters focus on problem areas including the hazards of foodborne bacterial infections and intoxications, mycotoxins and toxic stress metabolites, environmental contaminants in food, and hazards of compounds in human nutrition. The last section tackles the close relationship of toxicology with food, including their effects and applications. Some topics include food colors, ingredients, chemicals, and substances, as well as their effects on other organisms. This volume will be invaluable to students and professionals in nutrition and toxicology. Other people who studies nutrition, toxicology, and pharmacology will also benefit from this resource.

Now, more than ever, foods come packaged in containers designed for direct cooking or heating, which often causes the movement of substances - indirect additives - into foods. Because of their unique characteristics, plastics or polymeric materials (PM) have become the most important packaging material for food products. The safety assessment of plastics intended for use in contact with foodstuffs or drinking water continues to present a serious challenge. Indirect Food Additives and Polymers: Migration and Toxicology studies the potential hazards of indirect additives for human health and develops recommendations for their safe manufacture and use. It contains an impressive review of basic regulatory, toxicological, and other scientific information necessary to identify, characterize, measure, and predict the hazards of nearly 2,000 plastic-like materials employed in packaging. The author presents the data underlying federal regulations - previously unavailable a single volume. The entry for each chemical provides: Prime Name Molecular or Structural Formula Molecular Mass Synonyms CAS Number RTECS number Properties Application and Exposure Migration Data Acute Toxicity Repeated Exposure Short-Term Toxicity Long-Term Toxicity Immunotoxicity of Allergenic Effect Reproductive Toxicity Mutagenicity Carcinogenicity Chemobiokinetics Standards Guidelines Regulations Recommendations References International in scope, the Handbook of Indirect Polymeric Additives in Food and Water: Migration and Toxicology offers comprehensive data on the toxic effects of polymeric materials and their ingredients. You will find the most information on plastics and polymeric materials- their migration and toxicology - in this resource.
