COLUMBUS, Ohio (WCMH) – As fishing season returns in full force, the Ohio Department of Health recommends anglers check their catch to make sure they’re not consuming too many toxins.
The Ohio Sport Fish Consumption Advisory sets maximum consumption guidelines for fish from Ohio’s waters. Ranging from recommending several servings a week to avoid eating at all costs, the advisory outlines contaminants that accumulate in fish, including mercury, arsenic and polychlorinated biphenyls.
Dozens of Ohio bodies of water have species-specific guidelines, but the advisory also has general guidelines for all species of fish in all bodies of water. Under the guidelines, one serving of fish is 4 to 6 cooked ounces for adults and 2 to 3 cooked ounces for children.
Unless otherwise specified, general guidelines recommend one serving of Ohio-caught fish per week. According to the advisory, all listed frequencies are designed to be safe for consumption by pregnant people and young children, who are more susceptible to health effects from contamination. You can find an interactive map of fishing advisories here.
Below are images of the most common sport fish in Ohio, from the Ohio Department of Natural Resources.
