LANSING, MI — The state government this week issued new fish consumption advisories for lakes and rivers in three counties after tests confirmed the presence of toxic chemicals.

Fish in three lakes and a section of the Au Sable River were tested as part of state response to revelations about per- and polyfluoroalkyl substances, also called PFAS or PFCs, according to a Michigan Department of Health and Human Services press release.

The tests found elevated levels of one of those chemicals, PFOS, as well as mercury in multiple fish species collected from Freska Lake and Versluis Lake in Kent County, Lake Margrethe in Crawford County and a section of the Au Sable River between Grayling and Mio.
