Louisiana health officials say they are reopening some oyster harvest areas where the threat of flooding from Tropical Storm Karen has diminished.

Louisiana harvest areas 13 to 23 will open Sunday morning. They were among the areas ordered closed because of the possibility of contamination from flood waters.

Saturday's announcement said a precautionary closure of oyster harvest areas one through 12 would remain in effect until health officials determine the waters meet standards set by the National Shellfish Sanitation Program.

The state Department of Health and Hospitals has reopened some of the oyster beds that were closed Aug. 28 as a precautionary measure in advance of Hurricane Isaac.

Oyster harvesting areas located in coastal areas of St. Bernard, Plaquemines, Jefferson and Lafourche parishes reopen Monday.

Some harvest areas in those parishes will remain closed, however, until health officials determine the waters are clear and within approved area criteria established by the National Shellfish Sanitation Program, which is part of the federal Food and Drug Administration.
