LANSING, Mich. — According to the Michigan Department of Health and Human Services (MDHHS) there are high levels of perfluorooctane sulfonate in Lake Superior rainbow smelt. Information MDHHS received from Wisconsin Department of Natural Resources prompted the latter to issue an Eat Safe Fish warning.
The warning recommends people limit their Lake Superior smelt consumption to one serving (an 8-ounce portion for adults and 2/4 ounce portion for children) monthly.
“This precautionary guideline is based on data shared by Wisconsin, which shows elevated levels of PFOS in Lake Superior rainbow smelt,” said Dr. Joneigh Khaldun, chief medical executive and chief deputy for health. “PFOS is a perfluoroalkyl substance (PFAS) associated with harmful effects in people, including reduced fertility, thyroid disease and liver damage. We will update this guideline once the department has additional data.”
