Dangerous ‘forever chemicals’ found in blood of residents near UK factory

Blood tests have found high levels of cancer-causing “ forever chemicals ” in residents living near a large Lancashire chemical factory.

Almost 70 per cent of the 49 Thornton-Cleveleys residents tested had increased levels of a chemical known as perfluorooctanoic acid, or PFOA, a substance banned as it has been classed as a carcinogen. Those affected live near the Hillhouse manufacturing site, operated by AGC Chemicals Europe and formerly by ICI, which used PFOA between the 1950s and 2012.

Law firm Leigh Day said the elevated levels of the chemicals placed residents at higher risk of developing health problems such as high cholesterol and some cancers.

PFOA is part of the “ PFAS ” group of substances, used in a range of products from pesticides to non-stick cookware, food packaging and waterproof clothing, which are known as “forever chemicals” as they can take centuries to break down in the environment.

The local authority, Wyre Council, launched a multi-agency investigation in 2024 into whether PFOA used on the site and released into the air had contaminated surrounding land, and has temporarily closed allotment sites over contamination.

The Food Standards Agency has advised people living within 1km of the site to wash and peel home-grown produce to remove soil that could be contaminated with PFOA, before eating.

Those residents should not consume home-produced eggs, it warned, after tests revealed eating a single egg a week could reach or go over weekly safety limits.

Leigh Day , which has been investigating PFAS contamination in the area, said it worked with experts led by Dr Dave Megson at Manchester Metropolitan University (MMU) in association with Watershed Investigations on PFAS investigations in the area.

As part of that work, tests were arranged for 49 residents over this summer, selected on how near the factory they lived, how long they had lived there and whether they ate local produce.

The results showed levels of PFOA above 20 nanograms per millilitre in 69 per cent of those tested, putting them in the high-risk category, with the overall average at 26 nanograms per millilitre, Leigh Day said.

None of the participants had a result in the low-risk category, of less than 2 nanograms per millilitre.

Higher than average levels of PFOA were found in those living within a kilometre of the industrial site, while three quarters of those who ate home-grown fruit and vegetables were found to be in the high risk category.

Leigh Day partner Sarah Moore, who leads the firm’s investigations, said: “The results of our testing project in Thornton-Cleveleys are hugely concerning.
