Effects of post-event event effluent on sea fishing

[Grumpy Grandpa]

I'd briefly mentioned this on the thread about fly fishing and was rightly reminded that it should really have a separate thread...

So - I live on the North Ayrshire coast and I've considered that seafood would be an ideal source of food for anyone living in this area and in others but there is a question about sea fishing post event that's been worrying me.

Post a large event, I'm sure that the under or unmanning, or failures in maintenance in treatment stations, would result in an increased volume of effluent entering the coastal waters that we would be harvesting from.

Does anyone have any information on whether this would pose any significantly increased heath risk?
