Does cooking food kill all bacteria?

Cooking food kills some bacteria but does not destroy all. Many bacteria have adaptable cell walls that may become resistant to certain modes of attack. This means that if you apply heat or chemicals to kill bacteria multiple times, you will get less benefit from it each time.

How long does it take to cook germs off of food?

Active bacteria are killed by holding the stock at 150 degrees or higher for one minute, while botulinum toxin is inactivated by boiling for 10 minutes. However, quickly reheating contaminated stock to serving temperature does not destroy its active bacteria or toxins, and the stock makes people sick.
