Effects of post-event event effluent on sea fishing

[BDG]

In the middle ages, the lord of the manor was entitled to most of the waste the peasants produced. Meant he had a better food source so him and his offspring would out perform the peasants due to the extra manure.

If you do not want to use human waste on food crops, use it on fuel and timber crops.

I would be more worried about heavy metal accumulation than poisoning, but only because I could take precautions against poisoning - good gutting and cleaning, good cooking, fresh fish. If I suspected an area of very bad industrial pollution, I would stay away from it.
