I live near the Great Lakes, so there is literally no such thing as a safe fish to eat. Every fish has a limit to how much you can eat and how often -- that is if you are an adult male, if female or child you are far more limited yet.

Especially near me, where the waterways are also toiletways. You'd have to go out into the lake to escape the toilet and dioxin-laden water, where the fish should never be eaten, and even then you have, like I said above, a limit depending on how much toxic fish you feel comfortable ingesting.
