PFAS Chemicals Contaminate U.S. Food Supply, FDA Confirms
The U.S. Food and Drug Administration (FDA) has found per- and polyfluoroalykyl substances, or PFAS, in foods including grocery store meat, fish and chocolate cake, The Associated Press reported Monday.
The FDA tests found PFAS in chocolate cake at levels more than 250 times the only federal safety guidelines that exist, for some types of PFAS in drinking water, according to The Associated Press.
"What this calls for is additional research to determine how widespread this contamination is and how high the levels are," Director of the National Institute of Environmental Health Sciences Linda Birnbaum told The Associated Press. "We have to look at total human exposure — not just what's in the water or what's in the food ... or not just dust. We need to look at the sum totals of what the exposures are."
CNN explained why PFAS contamination is so concerning:
PFAS is a family of nearly 5,000 synthetic chemicals that are extremely persistent in the environment and in our bodies. PFAS is short for perfluoroalky and polyfluoroalkyl substances and includes chemicals known as PFOS, PFOA and GenX, sometimes called forever chemicals. These chemicals all share signature elemental bonds of fluorine and carbon, which are extremely strong and difficult to break down in the environment or in our bodies.
These chemicals can easily migrate into the air, dust, food, soil and water and can accumulate in the body. They've been linked to adverse health impacts including liver damage, thyroid disease, decreased fertility, high cholesterol, obesity, hormone suppression and cancer.
They were invented by DuPont in 1938, initially for non-stick cookware. But they are now used by a variety of industries to repel grease and water in items from packaging to carpets to outdoor gear, and they are also an important ingredient in firefighting foam, which is often used by the Defense Department to fight jet fires, The Associated Press reported.
The U.S. Environmental Protection Agency gives the safe level for certain PFAS in drinking water at 70 parts per trillion (ppt).
The FDA's most recent PFAS findings were presented at the 29th annual European meeting of the Society of Environmental Toxicology and Chemistry in Helsinki, Finland last month, and photos of the presentation were obtained by EDF, according to CNN. The findings contained three related investigations into PFAS in food, as EDF summarized:
1. The FDA found most of 16 PFAS tested for in food sold at a farmer's market downstream of a PFAS facility. One produce sample contained 1,200 ppt.
2. In an investigation of a dairy farm near an air force base in New Mexico, the agency found the PFAS perfluoroctanesulfonate (PFOS) at levels of more than 5,000 ppt in milk samples. It also found lower levels of various types of PFAS in cheese.
3. A sampling of food from grocery stores in three mid-Atlantic cities in October 2017 turned up 17,640 ppt of PFAS in chocolate cake, and detectable levels of PFOS in 10 of 21 meat samples, from 134 ppt in a frankfurter to 865 ppt in tilapia.
FDA spokeswoman Tara Rabin told The Associated Press that the levels found by the agency were "not likely to be a human health concern."
However, East Carolina University toxicologist Jamie DeWitt said the important question was the impact of contamination over time.
"Drinking one glass of contaminated water is unlikely to be associated with health risks, as is eating one slice of contaminated chocolate cake," DeWitt told The Associated Press. "Individually, each item is unlikely to be a huge problem, but collectively and over a lifetime, that may be a different story."

Well, he told us he would do it. And now he's actually doing it — or at least trying to. Late last week, President Trump, via the U.S. Department of the Interior's Bureau of Land Management, announced that he was formalizing his plan to develop lands that once belonged within the Bears Ears and Grand Staircase-Escalante National Monuments in southern Utah. The former is a stunningly beautiful, ecologically fragile landscape that has played a crucial role in Native American culture in the Southwest for thousands of years; the latter, just as beautiful, is one of the richest and most important paleontological sites in North America.
