North Carolina health officials put eating limits on fish due to contamination from 'forever chemicals'

North Carolina health authorities have recommended limits on the consumption of certain freshwater fish from the middle and lower Cape Fear River due to concerns over contamination from "forever chemicals." 

The North Carolina Department of Health and Human Services said Thursday that the recommendation was based on concerns about exposure to perfluorooctane sulfonic acid found in the fish sampled from that area. 

PFOS is part of the chemicals called per- and polyfluoroalkyl substances, known as PFAS. They are chemicals that do not break down in the environment.

The department said these conclusions were based on newly available data and information from the U.S. Environmental Protection Agency and that fish advisories are issued to help Americans weigh the value of eating fish with the risks of pollutants that fish absorb from their environment.
