You have a wonderful assortment of organic, local vegetables that you are ready to cook. You pour a little olive oil into your non-stick pan and saute your veggies. What do you get? Delicious sauteed veggies with a side of perfluorooctanoic acid (PFOA). Wait, what?
What is PFOA?
PFOA is the chemical used to make the non-stick coating on cookware (pots, pans, muffin tins, baking sheets, etc.) and electric cooking appliances (griddles, indoor grills, sandwich makers, etc.). Products with Teflon can contain levels of the chemical or similar chemicals (such as Polytetrafluoroethylene or “PTFE”). PFOA is widely used in other products such as carpet, fast food wrappers, stain-resistant clothing, and in water repellents for fabric and upholstery.
We are exposed to PFOA through drinking water, air, dust, food packaging, breast milk, umbilical cord blood, and microwave popcorn. When non-stick cookware is exposed to high heat, the chemical gets into the air and there can be a risk of PFOA exposure.
On the Environmental Protection Agency’s website, this is what they have to say about PFOA:
“Perfluorooctanoic acid (PFOA), also known as “C8,” is a synthetic chemical that does not occur naturally in the environment… EPA has been investigating PFOA because it:
- Is very persistent in the environment
- Is found at very low levels both in the environment and in the blood of the general U.S. population
- Remains in people for a very long time
- Causes developmental and other adverse effects in laboratory animals.”
When tested, the chemical has been found in all or virtually all people’s blood, including newborn infants. Many animal and human studies over the years have shown that PFOA may cause a multitude of health concerns. These include, low birth rates, developmental delays, various forms of cancer, tumors, and liver toxicity; although the makers of PFOA maintain that the chemical is safe for humans and there is no reason for concern.
PFOA and Children
A recent September 2010 study from the West Virginia University Health Sciences Center studied 12, 476 children and was titled, Compounds in non-stick cookware may be associated with elevated cholesterol in children and teens. The study found PFOA and a related chemical, perfluorooctanesulfonate (PFOS), at higher levels than expected. In addition, the children and teens with these higher blood levels, “…appear more likely to have elevated total and LDL cholesterol levels according to a report in the September issue of Archives of Pediatrics & Adolescent Medicine, one of the JAMA/Archives journals.” While the study does not definitively prove a causal effect between PFOA and elevated cholesterol levels, the results should be enough to make any parent think twice about the chemical.
What Should I Do?
It is impossible to completely avoid PFOA exposure since it is found everywhere. When possible, avoid clothing, fabrics, upholstery and furniture that is stain-resistant as the item likely contains PFOA. It is difficult to find alternatives, but more options are now available to concerned consumers.
Reduce exposure in the kitchen, by moving away from anything non-stick. In the spirit of self-disclosure, I personally have non-stick cookware in the house. We got rid of our non-stick pots and pans a few years ago, but I realized we still have non-stick muffin tins, baking dishes and loaf pans. However, after doing the research for this article, I will be switching away from using these items. While clean up with non-stick cookware is a breeze, the health implications associated with PFOA are just not worth it.
