Oh I have REAL LIFE first hand experience from friends of how bad it can truly be!

Years ago one of my friend's mom had a black American friend who was making some kind of chicken stew or something for her daughter's school. Not only did she was the chicken with dish soap but then put a god load of spice in this to make it nuclear waste. After cooking it, let it sit overnight so it got worse then tasting it the next morning, decided to drain some of it away and dilute it with water

Luckily, my guy's mom was smart and refused to try any.
