An amended regulation from the FDA:
The Food and Drug Administration (FDA) is amending the agency’s regulations to prohibit the use of certain cattle origin materials in the food or feed of all animals. These materials include the following: The entire carcass of bovine spongiform encephalopathy (BSE)-positive cattle; the brains and spinal cords from cattle 30 months of age and older; the entire carcass of cattle not inspected and passed for human consumption that are 30 months of age or older from which brains and spinal cords were not removed; tallow that is derived from BSE-positive cattle; tallow that is derived from other materials prohibited by this rule that contains more than 0.15 percent insoluble impurities; and mechanically separated beef that is derived from the materials prohibited by this rule. These measures will further strengthen existing safeguards against BSE.
DATES: This final rule is effective April 27, 2009. The Director of the Office of the Federal Register approves the incorporation by reference in accordance with 5 U.S.C. 552(a) and 1 CFR part 51 of a certain publication in new 21 CFR 589.2001 effective April 27, 2009.
