State regulators are reconsidering the science behind ‘do not eat’ advisories for PFAS in fish.

Stronger guidance could mean more Michigan fish being flagged with health warnings, threatening a $2.3 billion fishing economy.

According to Bridge Michigan, dozens of Michigan bodies of water currently have fish under PFAS contamination advisories.

And, the number could grow as state officials reconsider how much of the tainted fish is safe for people to eat.

Environmental groups are to credit for causing the review, as they say they are worried that Michigan’s guidelines are reliant on outdated science.
