Area 23, a shellfish harvesting zone off the Louisiana coast roughly equal in size to the city of New Orleans, was closed this week after health officials linked a norovirus outbreak to its oysters.
An investigation into the outbreak that sickened 14 people who ate oysters at a Louisiana restaurant determined that the oysters were tainted before they arrived at the restaurant. Health officials issued a recall of the oysters and the temporary closure of Area 23.
