The FDA says their own tests did not turn up any acetaminophen in pet food. However, the FDA did not test the same samples as ExperTox.
“My bottom line is I’m pretty confident in the FDA’s findings,” said Dr. Steven Hansen, lead veterinary toxicologist with the American Society for the Prevention of Cruelty to Animals’ animal poison control center. “Acetaminophen is not hard to find.”
The FDA found no trace of the medication in five samples of one type of cat and two dog foods it tested in the past week, said spokesman Mike Herndon.
“At this point, FDA sees no compelling need to analyze any more samples for acetaminophen,” he said.
ExperTox Inc., in Deer Park, Texas, found varying levels of acetaminophen — which is toxic to pets, especially cats — in up to a dozen samples, lab operations manager Donna Coneley said Monday. She did not return calls yesterday seeking comment on the FDA’s findings.
It is not clear, however, whether the agency tested the type of food in which ExperTox said it found the highest level of acetaminophen. That sample had been submitted by the manufacturer, according to Coneley. FDA officials did not contact ExperTox until yesterday.
Agency and lab officials are reviewing scientific data, said Julie Zawisza, assistant commissioner of public affairs for the FDA.
“We cannot validate their findings,” she said. “… If they give us something new, we’ll look into it.”
A third lab hired by a pet food company and a university lab hired by a consumer could not verify ExperTox’s findings, Zawisza said.
