The state has also ordered a recall of all oysters harvested from the area since April 26, including shucked, frozen, breaded and post-harvest processed oysters, and oysters for the half-shell market.
The contaminated oysters were not distributed or sold in the Terrebonne and Lafourche area, said State Health Officer Jimmy Guidry with the Department of Health and Hospitals.
The outbreak of norovirus was contained to the New Orleans area. Oysters were recalled from three other states, Maryland, Texas and Georgia.
A total of 1,141 sacks of oysters were recalled.
Norovirus is a virus that causes what is commonly called a “stomach flu” or “food poisoning.” Symptoms usually begin 24-48 hours after exposure, and can include nausea, vomiting, diarrhea and stomach cramping. Some people may also suffer chills, headache, muscle aches and fatigue.
The illness is usually brief, lasting one to two days. The virus is extremely contagious, and can be contracted from an infected person, by eating contaminated food or water or by touching a contaminated surface.
