The Michigan departments of Health and Human Services (MDHHS) and Natural Resources (DNR) today issued a ‘Do Not Eat’ advisory for deer taken within approximately five miles of Clark’s Marsh in Oscoda Township. The advisory is due to high levels of PFOS (perfluorooctane sulfonic acid) found in a single deer taken about two miles from Clark’s Marsh, which borders the former Wurtsmith Air Force Base. PFOS is one type of PFAS (per- and polyfluoroalkyl substances) chemical.
One deer out of twenty tested around the former Wurtsmith Air Force Base was found to have high levels of PFOS. The level of PFOS in the muscle of the deer was 547 parts per billion, exceeding the level of 300 ppb at which action is recommended. PFAS was either not found or was at low levels in muscle samples from the other 19 deer. Although only one deer of this group tested at such high levels, the advisory was issued to protect the health of anyone eating venison taken within approximately five miles of Clark’s Marsh. The state has plans to test more deer from this area.
The five-mile radius encircles the Wurtsmith base property and covers what the DNR has estimated to be the expected travel range of deer living in or near the marsh. The area covered by the deer consumption advisory issued can be described as:
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.
