Effective at sunset Tuesday, oyster harvest areas 1-28 — from Lake Borgne in St. Bernard Parish to Vermillion Bay in Vermilion Parish — will be closed.
The state Department of Health and Hospitals announced the precautionary closure because Tropical Storm Isaac, which is expected to strengthen into a hurricane, could cause flooding in coastal parishes that would cause natural contaminants to be washed into rivers, bayous and streams and possibly into oyster-growing areas.
The areas will stay closed until such time as state health officials determine the waters are safe.
