Residents near Lancashire chemicals plant told to wash homegrown produce

Exclusive: council issues advisory as investigation begins and documents reveal estimates of PFOA emissions

People living near a chemicals plant in Lancashire have been told to wash and peel vegetables from their gardens before eating them, while an investigation into potential contamination of soil in the area with a banned toxic chemical gets under way.

The chemical PFOA, one of the PFAS family of about 15,000 chemicals, does not break down in the environment and last year was categorised as a human carcinogen by the World Health Organization. It is also toxic to reproduction and has been linked to a range of health problems such as thyroid disease and increased cholesterol.
