What are The Health Risks Associated with Perfluorooctanoic Acid (PFOA)?

Read Transcript

PFOA is part of a family of fluorinated non-stick chemicals. They're used in non-stick cookware in stain resistant fabrics and in the liners of microwave popcorn bags. They've been very useful, but there have been a number of health concerns. Thankfully some of the more problematic ones are being faced out.

There has been a lot of controversy over PFOA but it's pretty clear that it raises cholesterol in people, a big public health concern but beyond that higher levels of PFOA have been linked to higher chances of bladder cancer, to kidney cancer, to ulcerative colitis, to thyroid disease.

There is a number of things, but here is the problem with PFOA. PFOA a body doesn't know how to get rid off very well, so once you do get exposed to it, its likely exposed again, so the level keeps stair stepping up and can accumulate and accumulate over time. Most people don't know this, but it's been estimated that 20% of the PFOA in our bodies, comes from microwave pop corn.
