killed by cooking

Why food that has had bacteria growing on it can cause food poisoning even when the bacteria have been killed?
You can become intoxicated as in the case of Clostridium botulinum (botulism) or Staphylococcus aureus (caused by Staph. Super Antigens).





I am going to add, however, that those toxins are generally destroyed by cooking. But the theoretical answer to you question is definitely because the bacteria have secreted toxins which make you ill upon consumption.
Reply:who said that?





Cooking is to kill bacteria. Unless you mean like parasites etc. Not cooking well or thoroughly enough doesn't kill them (or kill them all) which causes food poisoning
Reply:Because the bacteria produce toxins as waste products in their growth. Heat can kill the bacteria but won't destroy the toxins. Botulism is a good example of this.
Reply:Bacteria secretes toxins that might survive cooking that kills the bacteria itself.
Reply:if the food has been cooked, then set on a contaminated surface-welcome to the world of food poisoning!! also if it is not cooked thouroughly some bacteria and parasites will form endospores that keep them protected until things are safe again. also, when people handle your cooked food after taking a bit **** and not washing their hands, that can make you sick as well.
