Irradiation in the Production, Processing, and Handling of Animal Feed and Pet Food
21 CFR Part 579 establishes safety standards for using ionizing radiation in animal feed and pet food production. Facilities may use gamma rays (cobalt-60, cesium-137) or electrons (up to 10 MeV) to treat complete animal diets and ingredients. For poultry feed, additional X-ray sources are permitted. Minimum effective dose for salmonella control is 2.0 kGy; maximum is 25 kGy. Facilities must comply with Part 507 and incorporate applicable Part 179 food irradiation regulations.
Food Additives Permitted in Feed and Drinking Water of Animals
21 CFR Part 573 establishes permitted food additives for animal feed and drinking water. Regulations cover acrylamide-acrylic acid resin as a thickener/suspending agent in aqueous feed suspensions, aminoglycoside 3'-phosphotransferase II enzyme for genetic modification of crops, ammoniated cottonseed meal as a protein source in ruminant feed (max 20% of ration), and ammoniated rice hulls as fiber and nonprotein nitrogen source in beef cattle feed (max 20% of ration). Each additive includes specifications, approved uses, and labeling requirements for safe application.
Requirements for Blood and Blood Components Intended for Transfusion or for Further Manufacturing Use
21 CFR Part 630 establishes minimum criteria for blood and blood component donations intended for transfusion or further manufacturing. Blood establishments must determine donor eligibility, assess donation suitability, and notify deferred donors. The regulation defines key terms including blood, blood components, donors, and relevant transfusion-transmitted infections (HIV, HBV, HCV, HTLV, syphilis, West Nile virus, Chagas disease, CJD, vCJD, and malaria). Requirements apply to establishments manufacturing blood and blood components.
Intentional Genomic Alterations in Animals

Food and feed restrictions apply to certain lineages.
Substances Generally Recognized as Safe
21 CFR Part 582 establishes the regulatory framework for substances generally recognized as safe (GRAS) for use in food and animal feed. The regulation defines GRAS status, outlines good manufacturing and feeding practices including restrictions on quantities, and authorizes the FDA Commissioner to maintain lists of approved substances such as spices, essential oils, natural seasonings, and flavorings. Substances must be of appropriate grade and prepared as food ingredients, with quantities limited to what is reasonably necessary to accomplish their intended effect.
Interstate Conveyance Sanitation
21 CFR Part 1250 establishes sanitation standards for interstate conveyances (land, air, and water carriers) to prevent transmission of communicable diseases. It defines key terms including contamination, potable water, food service utensils, and shellfish, and references CDC quarantine requirements. The regulation covers bactericidal treatment, waste management, and sanitation practices for vessels and conveyances engaged in interstate traffic.
Regulations Under the Federal Import Milk Act
21 CFR Part 1210 establishes regulatory requirements for imported milk and cream under the Federal Import Milk Act. It defines milk, cream, and related dairy products; specifies pasteurization standards (minimum 143°F for 30 minutes or 161°F for 15 seconds); and requires dairy farms and processing plants to undergo sanitary inspections scoring at least 50 out of 100 points and be available for examination by authorized agents. The rules apply to all milk and cream offered for import into the continental United States.
