PFOA is a persistent organic chemical used in industrial and consumer goods including nonstick cookware and stain- and water-resistant coatings for carpets and fabrics." Florine is a halide like iodine. So Lugol's Iodine or Iodoral may be a good antidote. Old fashioned cast iron pans or vitreous (glass) enamel might be our best substitute for cookware.
