Officials with the Alabama Department of Health are investigating a foodborne outbreak reported late last month in southwest Alabama suspected to be linked to oysters from Louisiana that left nearly a dozen people ill, the agency said Thursday.

The department is also investigating two foodborne illness complaints associated with oyster consumption.

Eleven people became ill, including three who sought emergency room treatment, according to the agency.

As of Thursday, no one involved has been hospitalized, the department said.

The Louisiana Department of Health ordered a recall of all oysters harvested from one oyster harvesting area since Jan. 10, including shucked, frozen, breaded, post-harvest processed, and oysters for the half-shell market.

The recall was issued due to norovirus-like illnesses reported in the area after the oysters were eaten.

Fifteen people became ill with norovirus-like illness after eating the Louisiana oysters at several New Orleans restaurants between Jan. 15 and Jan. 31, according to ADPH.

The Louisiana Department of Health reported the illnesses were not life-threatening, but two people in Louisiana were hospitalized and have since been discharged.

The ADPH Seafood Branch has notified all oyster shippers with Alabama permits that the recalled Louisiana oysters distributed in Alabama have been associated with foodborne illnesses. The oyster shippers have told their customers about the recall and advised them to return or destroy the suspected affected product. Several Alabama shippers have distributed this product, and ADPH said it is verifying that Alabama commercial customers are holding the product.

Norovirus-like symptoms can include nausea, vomiting, diarrhea, abdominal pain and/or cramps. Norovirus can also cause fever, chills, headache, body ache, and muscle cramps. More information can be obtained from the Centers for Disease Control and Prevention’s (CDC) section on Nororvirus.
