What fish are safe to eat in St. Clair County? Here's what Michigan health department says
The Michigan Department of Health and Human Services has released a guide on what fish are safe to eat, if you should limit servings and what fish to keep off your plate.
The 2025 Eat Safe Fish Guide provides Michigan residents with safety information for fish in popular fishing locations. Each year, MDHHS tests fish to determine what chemicals are present in those fish, including polyfluoroalkyl substances, also known as "forever chemicals."
"Using the ESF Guide and following the MI Serving suggestions will keep you from getting too many chemicals in your body at once," the guide states in its FAQ section. "Scientists set the limits in the ESF Guide so that you are protected from possible health problems from the chemicals, no matter how long they stay in your body."
The guide includes sections on each county, including St. Clair County, a popular fishing destination. The guide breaks the portions of fish down by species and what body of water it comes from.

Fish recommended for limited servings are recommended to not be eaten by children under 15, anyone with health problems, or people who are pregnant or plan to have kids.
The department notes in its guide that its serving are only suggestions, and that eating more than the recommended amount does not guarantee the fish will make a person sick. For anyone else the guide recommends only one or two servings per year.
More information, including how each concerning chemical can affect those who eat fish and what fish are safe in each Great Lake are safe to eat are available in the guide on the department's website.
