(St. Paul, MN) — The Minnesota Department of Health is issuing new guidelines for exposure to a group of chemicals known as PFAs. The agency announced yesterday that it was lowering the acceptable level of contamination for PFAs found in drinking water. The state health department says it’s unlikely that Minnesotans can eliminate their exposure to PFAs, since they are found in food packaging, cookware coatings, cleaning products and other materials. But health officials recommend reducing PFA exposure to prevent health effects such as changes in liver function and reduced immune response.
