The U.S. Food and Drug Administration has found a euthanasia drug in several brands of dog food, leading some brands to issue a voluntary recall and causing concern among pet owners.

The FDA says that such a low level of this drug in pet food is unlikely to seriously harm pets. However, no amount of sodium pentobarbital, a common lethal drug used to put animals to sleep, is acceptable in pet food, the agency warns.

The J.M. Smucker Company, famous for Smuckers Jam, has responded to this report by issuing a voluntary recall of the tainted pet foods they sell. Pet food with the labels Gravy Train, Ol’Roy, Kibbles N’ Bits, or Skippy Premium, can be returned to the store for a full refund. The FDA asked pet stores to stop selling these brands immediately. The same goes for the dog food brand Against the Grain, which also issued a recall last week for the same concern.
