Those who eat fish two or more times a month from the Detroit River have higher levels of mercury, PCBs and dioxins.
People who eat fish from the Detroit River two or more times per month have higher toxin levels in their blood and urine than national averages, a recent state health department study showed.
Blood and urine samples taken from 273 frequent river anglers had two to three times the average amount of mercury and PCBs, as well as elevated dioxin levels, according to the Michigan Department of Health and Human Services.
The findings, state health officials say, highlight the importance of following Michigan‘s Eat Safe Fish guidelines, which list the toxins suspected in different types of fish and how many meals of those fish are safe to eat in a month or year. That may be easier said than done for many metro Detroit families who rely on fish they catch from the river as a food staple.
