Three state agencies say nobody should eat fish or crawfish from the Devil’s Swamp and Bayou Baton Rouge area, or swim or boat there, because of mercury and PCB pollution.

The Departments of Health and Hospitals, Environmental Quality and Wildlife and Fisheries say Wednesday’s advisory replaces one against eating fish from the area more than twice a month. That advisory had been in effect since 1993.

The Environmental Protection Agency has said a nearby 190-acre hazardous waste dump was the apparent source of PCBs.

Rollins Environmental Services Inc. ran the site for decades starting in 1971. Current owner Clean Harbors Inc. said in a federal filing last year that it’s doing some cleanup work under a state order and is working on a study ordered by the EPA.
