State Health officials say contamination from Clarks Marsh in Iosco county has made fish from that area unsafe to eat.
An advisory warning people not to eat fish from that area has been issued until further notice.
Perfluorinated chemicals have been detected in Pumpkinseed and bluegill fish.
Angela Minicuci is with the Michigan Department of Community Health.
She said the contamination is suspected to be caused by the use of fire-fighting foams used at a nearby air force base.
She said if consumed PFC will not have an immediate effect.
"Some studies have identified some on-going health effects such as liver, thyroid or immune system problems. In laboratory animals, offspring from treated animals have had developmental delays. So if someone has eaten it, it's not a major concern right now. One of the things with PFC's is it can build up in your system so we want to make sure people aren't putting it in their system to begin with."
Minicuci said restaurants and grocery stores have been advised not to sell fish from that area.
The Department of Environmental Quality is working to find a solution to the contamination.
