|The Ohio River Valley, where Teflon has been manufactured for decades|
This study was conducted in the Ohio River Valley as part of a class action lawsuit against DuPont, the makers of Teflon. DuPont's manufacture of Teflon-containing products, including non-stick cookware, has polluted the area's ground water with PFOA and PFOS.
While DuPont and other manufacturers have agreed to phase out the use of PFOA in their manufacturing processes by 2015, little is known about the safety of the new chemicals that will replace PFOA. I don't believe that the money allocated for the review of chemical alternatives to PFOA is sufficient.
In the face of continued political pressure to reduce the EPA's ability to perform its functions—thereby putting corporations in charge of public health—the conservative approach is to seek alternatives to Teflon cookware in your home.
It is likely in this case that the manufacture of Teflon-containing products was responsible for the elevated blood serum levels of PFOA in these children (as opposed to the use of Teflon-containing cookware). However, because PFOA off-gasses from non-stick cookware under normal use, I recommend you throw out your Teflon and other non-stick cookware in favor of cast iron cookware and stainless steel cookware.
