Perfluorooctanoic acid (PFOA)

PFOA is a synthetic persistent chemical, which is widely used in commercial and industrial manufacturing such as prominent consumer goods of non-stick cookware (Teflon), waterproof carpets, breathable clothing (Gore-Tex), filtration in water treatment processes, microwave popcorn bags and latex printing inks. PFOA persists indefinitely into the airwater, and soil as a toxicant and carcinogen. Once it is in the environment, our food and beverages are further exposed particularly fish, and sea food (i.e. shrimps, mussels, clams, and oysters).

PFOA,  its salts and PFOA-related substances (C8-chemistry) are identified as persistent, bioaccumulative, toxic and will be banned from 4 July 2020 in the European Union (EU Regulation under Entry 68 of Annex XVII of REACH). Until this regulation is implemented, there have been and are still cases where the exposure of PFOA are associated with increased risk of diseases such as below:

It is found that the greatest portion of the chronic exposure to PFOS are likely to result from the intake of contaminated foods, including drinking water. This is followed by the ingestion of dust and inhalation of air. Therefore, the most adequate starting point is eliminating the exposed foods and beverages as well as other related consumer products, and contacting producers and organisations to follow up the regulations to occur.
