Here I was under the impression that the water in the toilet is the same water as go into the taps, potable water, at least that's common here in Spain. Is it not the same in the US? Then both of them may have stagnant water or even "polluted" water in one way or another, but seems more or less the same.
You are if the fish ate any plants before they died (and you cooked with heat, I'm vegetarian so am unfamiliar with the other poster's a la Ceviche).
And even if the fish didn't eat any plants, you're still changing the protein structures — this is even part of the point of cooking, as amongst other things this does, changing the proteins inside the food is a process that kills any bacteria and other parasites.
Try it with dried cranberries and sunflower seeds for a great salad! (Don’t forget the salt, pepper, and garlic)
Moving a chemical process out of a living being and into a lab can make it safer: you’re doing it without the bacteria and viruses omnipresent in the natural world, and you know exactly what is going into the reaction…
When you “cook” a piece of fish in salt and lime (a la Ceviche) you are also altering the protein structures).
Sarcasm?
Language warning if you have kids around or don’t like that.
