You can catch 'em, but don't eat 'em
Hi, Frank!
You've already met my Beth here. She goes to college in Troy, NY, on the mighty Hudson. She likes to eat fresh fish, but not while at school. Women who may ever become pregnant are warned away from eating the fish caught in the river because of the level of PCBs found in the fish. There's a link in that article to the EPA's Hudson River site, for background and fairly current (March 2001) data on the problem.
The river's not dead, but it ain't too healthy for those at the top end of the food chain.
Regards--
Mary Anne
