Charleston, W.Va. (AP) -- Recent test results have prompted the state to revise its advisory for the consumption of channel catfish from the Monongahela River.
William Toomey with the Bureau for Public Health says the advisory now limits consumption based on the size of the fish.
Before, people were encouraged not to eat the fish.
Toomey says the advisory was modified after sampling conducted in 2005 and 2008 showed an improvement in the levels of PCBS, or polychlorinated biphenyls, in the fish.
The toxic material was used as a coolant in electric components until it was banned in the 1970s.
Toomey says with the revision, people should limit their consumption to two meals a month for fish larger than 17 inches.
Channel catfish below 17 inches can be eaten once a week.
