I completely agree with Erskin. My wife and I have a large garden and eat an abundance of fish and game. We even purchase pork and eggs that are raised locally. I believe the fish from the lake are fine in moderation. We eat a great deal of perch, bluegill, crappie and smaller game fish caught in smaller local lakes releasing the large breeders which being older, have potentially accumulated higher levels of contaminants.
My daughter, a doctor, is due with our first grandchild in August and she is being very careful with what she is consuming during her pregnancy and while nursing.
