FDA’s Animal-Drug Rule Amendment Allows More Progesterone Residues in Meat

Asserting that its technical animal drug-regulation amendment is not subject to congressional review, the Food and Drug Administration (FDA) has issued a final rule that increases the allowable residues of progesterone in edible tissues of cattle and sheep to reflect revised daily consumption values in a 1994 guidance document. According to the Federal Register notice, “Progesterone is approved for use in subcutaneous implants used for increased rate of weight gain in suckling beef calves and steers and in vaginal inserts used for management of the estrous cycle in female cattle and ewes.” The rule took effect on September 19, 2011, when it was published.
