Maine is shutting down shellfish harvesting in about a third of the state's coast because of a marine algae bloom that can carry a neurotoxin.

They've also issued a recall for mussels that would have been harvested in Frenchman Bay.

The Department of Marine Resources says the algae is being monitored for an acid that can cause sickness, memory loss and brain damage in humans.

The department found levels of the acid that exceeded standards in shellfish tested between Mount Desert Island and Gouldsboro.

Officials say mussels harvested from Frenchman Bay between September 10th and 14th have been recalled and shellfish dealers have been notified.

Although not part of the recall area, a larger section from Cape Jellison to Roque Bluffs has also been closed to shellfish harvesting as a precautionary measure.
