Over 15 people became sick with norovirus-like illnesses from eating raw oysters in Louisiana restaurants, according to the Louisiana Department of Health.
The Louisiana Department of Health has recalled oysters harvested east of Lake Borgne and north of Elio Bay, including the Chandeleur Islands and nearby marshes, between Jan. 15 and Jan. 31.
State health officials said that the recalled oysters include oysters that were shucked, frozen, breaded, post-harvest processed and those prepared for the half-shell markets in Oyster Harvesting Area 3. The area has been shut down and is expected to remain closed for at least 21 days.
Oysters are filter feeders that accumulate contaminants and microorganisms from the water. These can affect individuals who consume raw or undercooked contaminated oysters.
According to the Louisiana Department of Health, the 15 people who got sick reported norovirus-like illness after eating raw oysters at restaurants in New Orleans between Jan. 15 and Jan. 31. Two people who got sick were hospitalized but have since been discharged.
Symptoms of norovirus typically include stomach cramps, nausea, diarrhea, vomiting, chills, headaches, muscle aches, and a low-grade fever. The illness usually begins about 12 to 48 hours after someone has been exposed.
A person can get norovirus by eating or drinking liquids contaminated by infected handlers. However, outbreaks have also happened after people ate undercooked oysters from contaminated waters.
All Louisiana oysters harvested outside of Area 3, as well as all other Louisiana seafood statewide, are safe for consumption, the Louisiana Department of Health said.
