The Food and Drug Administration (FDA) is amending the regulations governing carcinogenicity testing requirements for food-producing animals.
The updated regulations eliminate the specific requirement that a sponsor has to conduct oral, chronic, dose-type studies. When the existing regulation was issued, chronic studies were the standard test for carcinogenicity. But research has shown that a chronic study may not be the best method for carcinogenicity testing, so the updated regulation allows for other study designs.
