Are clams good to eat from the James river?

Recreational harvest is prohibited.

The water in the James River is polluted and unsafe for human contact, including fishing, swimming, and kayaking as far upstream as Lynchburg. This is due to a number of factors, including sewage discharge, industrial runoff, and agricultural runoff. The pollution in the James River has led to a number of health problems in humans, including gastrointestinal illness, skin infections, and respiratory problems.
