The Michigan Department of Health and Human Services (MDHHS) has issued a warning to swimmers and outdoor enthusiasts to avoid frothy accumulations on lakes, rivers, and streams that could be laced with toxic substances, particularly PFAS.

"Foam containing PFAS is usually bright white, lightweight, and can pile up along shores or blow onto beaches," MDHHS officials cautioned, as reported by WWJ Newsradio. PFAS, or per- and polyfluoroalkyl substances are chemicals linked to health issues including high cholesterol, and liver damage, and are a health risk not to be taken lightly, as, health officials urge caution.

An earthy scent and off-white to brownish hue can distinguish naturally occurring foam from its dangerous counterpart. However, concern arises with the presence of the notably bright white foam that indicates the presence of PFAS. "Science tells us that the risk of PFAS entering your body through your skin is low, but you can accidentally swallow PFAS and other chemicals or bacteria if you do not rinse off or bathe after touching foam," Dr. Natasha Bagdasarian, chief medical executive at MDHHS, emphasized in remarks obtained by WNEM.

The MDHHS is recommending that anyone who comes into contact with the foam wash off as soon as possible, especially if PFAS contamination is suspected. Meanwhile, the Michigan Department of Agriculture and Rural Development is also sounding the alarm for pet owners, advising them to keep their animals away from the foam — who are "at risk" of ingesting the contaminated substance while grooming themselves, according to a report by ABC57.

For those with concerns about PFAS exposure or the foam itself, MDHHS has provided an Environmental Health Hotline at 800-648-6942. Individuals seeking additional information on this emerging health concern can also visit the MPART website for further guidance.
