FDA finds euthanasia drug in pet food ingredient

Pure tallow made by JBS Souderton for use in pet food contained the euthanasia drug pentobarbital, according to an FDA warning letter. The company, which does business under the name MOPAC, said it had cleaned equipment after the FDA and the Pennsylvania Department of Agriculture found lax testing protocols, but traces of pentobarbital were subsequently found, indicating that measures the company put in place were insufficient to prevent pentobarbital-contaminated ingredients from being used in finished tallow, according to the warning.
