The Michigan Health Department is continuing its issuing of a 'Do Not Eat' deer advisory within about five miles of Clark's Marsh in Oscoda Township.
With hunting season kicking off on Nov. 15, officials are reminding hunters of the potential health risk.
The advisory is due to high levels of PFAS discovered in one deer taken about two miles from Clark's Marsh, official say.
Areas in the advisory include:
From Lake Huron west along Aster Street, west on Davison Road, north on Brooks Road, east on Esmond Road, north on Old US 23, north on Wells Road, west on River Road, north on Federal Forest Road 2240, north on Lenard Road, north on Indian Road, and East on E. Kings Corner Road (along the county line) toward Lake to Lake Road, to Lake Huron.
Residents are also urged to avoid eating kidneys and liver from any deer because the PFAS chemicals can accumulate in their organs.
The advisory does not apply to cattle, chickens or other livestock raised in the area, according to the health department.
State officials say three labs will continue analyzing PFAS samples from the deer tissue.
