Fly Fishing

[Grumpy Grandpa]

My apologies if this is slightly off the thread on fly fishing but sea fishing has already come into the conversation and there is a question that's been bothering me for a wee while now...

I live on the coast of North Ayrshire and seafood would seem an ideal source of food for anyone living here but I have the recurring thought that post an event, there would be a huge increase in the volume of effluent entering coastal waters, with treatment stations being under/unmanned or not maintained.

Does anyone know if this would be likely to pose a significantly increased heath risk?
