“Much of America’s pet food packaging could be contaminated with PFAS ‘forever chemicals’, creating a potentially dangerous exposure to the toxic compounds for cats and dogs.

In a recent study public health advocate the Environmental Working Group (EWG) checked 11 bags of pet food and found that all of them contained the substance, including several at extremely high levels.

‘This represents a significant source of PFAS in the home environment,’ said Sydney Evans, a science analyst with the EWG.

PFAS, or per- and polyfluoroalkyl substances, are a class of about 12,000 compounds used to make products resist water, stains and heat. They’re called ‘forever chemicals’ because they don’t naturally break down, accumulating in humans and animals. PFAS are linked to a range of serious health problems like cancer, birth defects, kidney disease and liver disease.

The chemicals are likely used in pet food bags to make them repel grease. For cats, the highest levels were detected in the Meow Mix Tender Centers salmon and chicken flavors dry cat food, at more than 600 parts per million (ppm). Purina Cat Chow Complete chicken showed over 350 ppm, while Blue Buffalo, Iams and Rachael Ray Nutrish all had levels of less than 100 ppm.

For dogs, Kibbles ’n Bits bacon and steak flavor registered just under 600 ppm, followed by Blue Buffalo’s Life Protection Formula chicken and brown rice recipe at 150 ppm. Other dog foods made by Purina, Iams and Pedigree had much lower amounts. While some of the PFAS levels are considered by public health advocates to be high, no legal framework to measure it exists.” …
