Another Worry, PFAS Found in Pet Food – Truth about Pet Food

The consumer advocacy organization Environmental Working Group tested 11 bags of pet food for “total fluorine, which indicates the likely presence of PFAS. Four bags with the highest concentrations of fluorine were sent for additional tests, which revealed levels of specific PFAS compounds.”

Those four bags were:

Meow MixTender Centers Salmon & Chicken Flavors Dry Cat Food had the highest total fluorine, with 630 ppm. More tests found two PFAS at 5.5 parts per billion, or ppb.”

The sample of Purina Cat ChowComplete Chicken had total fluorine at 310 ppm. Additional tests revealed it was contaminated with six different PFAS at an alarming 245 ppb.”

Kibbles n’ Bits Bacon and Steak flavor registered 590 ppm of total fluorine. Additional tests found two PFAS at 14.3 ppb.”

Blue Buffalo’s Life Protection Formula Puppy Chicken and Brown Rice Recipe food had total fluorine of 140 ppm.”

There have been no pet food recalls – ever – for contamination with PFAS compounds. But in 2022, there were two human food recalls for PFAS compounds.

On 7/6/22 Bumble Bee Foods issued a recall “of smoked clams after FDA testing found detectable levels of PFAS chemicals in samplings of the product.”

And on 7/15/22 Crown Prince, Inc issued a similar recall of “canned Crown Prince Natural Smoked Baby Clams in Olive Oil because FDA testing found detectable levels of per- and polyfluoroalkyl substances (PFAS).”

Note that both recall notices stated “FDA testing” discovered the PFAS compounds in the human foods.

To our knowledge, FDA has never tested pet food for PFAS.

Considering the results of Environmental Working Group testing, pet owners need to ask the FDA Center for Veterinary Medicine to monitor PFAS compounds in pet food and as was done with human foods, issue recalls when detectable levels are found. Please email them at:
