Update September 16: S.C. Department of Health and Environmental Control has reopened shellfish beds.

Original post: Several of Charleston's shellfish areas are closed after Hanna dumped excessive rain, which can cause bacteria blooms. Get a map of shellfish areas here.

The SC DHEC said:
"The shellfish growing areas 6B, 7, 8, 9A, 10A and 11 in Charleston County, as well as the conditionally approved areas in Georgetown County, have been closed to shellfish harvesting because of rainfall from Tropical Storm Hanna and will remained closed until water quality sampling indicates bacteria levels are safe for shellfish harvesting," said Mike Pearson, manager of DHEC’s Shellfish Sanitation Program.
