(Reuters) -3M's Cynthiana facility received a subpoena in May seeking information about PFAS and alleged hazardous substances used or released at the site, the company's quarterly report on Friday showed.

The notice from the Kentucky Energy and Environment Cabinet also directed the company to develop a plan to investigate suspected release of the so-called "forever chemicals" at the plant.

3M has been battling suits accusing contamination from per- and polyfluoroalkyl substances, or PFAS, which is found in hundreds of consumer and commercial products, including cosmetics, non-stick pans and stain-resistant clothing.

They have been linked to negative health effects such as high cholesterol, low birth weights, reduced antibody response to vaccines as well as kidney and testicular cancers.

The company had announced in 2022 that it would exit all PFAS manufacturing by the end of 2025.
