Avoid foam this summer, officials warn of PFAS

Health officials are once again warning people to avoid foam on Michigan waterbodies, which may contain toxic “forever chemicals.”

Natural foam is usually brown or off-white with an earthy smell while foam containing PFAS chemicals is bright white and washes up on shorelines in billowy piles.

But the state advises Michigan residents and visitors to play it safe - and avoid making contact with any foam.

The state said the health risk from physical contact with PFAS foam is low, but it’s possible to accidentally swallow the foam. Prolonged exposure to the toxic chemicals is linked with certain cancers, liver damage, and other health impacts.

If you or your pet makes contact with foam, state officials recommend rinsing as soon as possible.
