Animal Drugs, Feeds, and Related Products; Famphur

요약

The Food and Drug Administration (FDA) is amending the animal drug regulations to specify the tolerance for residues of famphur in cattle products. The residue tolerances were originally issued in FDA's regulations under tolerances and exemptions from tolerances for pesticide chemicals in or on raw agricultural commodities, and subsequently moved to the Environmental Protection Agency's (EPA's) regulations for residues of pesticides. Subsequent FDA new animal drug approvals with the same tolerances, instead of stating the tolerances, cross-referenced EPA's regulations. This action is being taken because EPA has removed the tolerance from its regulations.
