Statewide advice:“Pennsylvania has issued a general, statewide health advisory for recreationally caught sport fish: eat no more than one meal (1/2 pound) per week of sport fish caught in the state’s waterways.”
“People who regularly eat sport fish, women of childbearing age and children are particularly susceptible to contaminants that build up over time.”
