That specific chemical compound is called perfluorooctanoic acid, or PFOA. Here's what you need to know. Sure, we've all said, "Eh, everything causes cancer," but the risks of PFOA are not over ...
2016 The EPA "published a voluntary health advisory for PFOA and PFOS" which warned that "exposure to the chemicals at levels above 70 parts per trillion, total, could be dangerous." [71] 2016 The city of Lake Elmo, Minnesota, sued 3M a second time for polluting their drinking water with PFAS chemicals.
In a U.S. Food and Drug Administration (USFDA) study, lipophobic fluorotelomer-based paper coatings (which can be applied to food contact paper in the concentration range of 0.4%) were found to contain 88,000–160,000 parts per billion PFOA before application, while the oil from microwave popcorn bags contained 6–290 parts per billion PFOA ...
PFOA was reduced from 70 ppt to 0.004 ppt, while PFOS was reduced from 70 ppt to 0.02 ppt. A safe level for the compound GenX was set at 10 ppt, while that for PFBS was set at 2000 ppt. While not enforceable, these health advisories are intended to be acted on by states in setting their own drinking water standards.
The EPA estimates thousands of PFAS are already in the U.S. environment and can be found in drinking water, soil, food, household items such as carpets and cookware, and more.
PFOS have many general uses such as stain repellents but have many properties which can make it a dangerous due to the fact that PFOS can be highly resistant to environmental breakdown. PFOS can be toxic in terms of increased offspring death, decrease in body weight, and the disruption of neurological systems.
Here’s what three food safety experts recommend. Why is storing produce in jars a cause for concern? There are a few potential things to have on your radar here.
PFOA persists indefinitely in the environment. It is a toxicant and carcinogen in animals. PFOA has been detected in the blood of more than 98% of the general US population in the low and sub-parts per billion (ppb) range, and levels are higher in chemical plant employees and surrounding subpopulations.
