What happen to the bacteria when food is cooked and when food is chilled?
Cooking kills bacteria but not the toxins the bacteria made while growing. Refrigeration does prevent most bacteria but not listeria which can grow in a refrigerator. Botulism is a toxin that does not go away with boiling or cooking.
What happens to most food poisoning bacteria when frozen?
Most food poisoning bacteria become dormant and stop multiplying when frozen. Freezing does not necessarily kill these bacteria, but it can slow their growth and reduce the risk of foodborne illness. However, once the food is thawed, these bacteria can become active again, so it's important to handle and cook frozen food properly.
Does cooked food remain free from pathogenic bacteria?
Cooking food can kill most pathogenic bacteria, making it safe to eat. However, once cooked food is exposed to the environment or handled improperly, it can become contaminated with pathogenic bacteria. It's essential to follow proper food safety procedures to prevent foodborne illnesses.
What is the food that bacteria cannot hurt?

What happens to bacteria when you dry them out?
When bacteria are dried out, their cellular functions slow down or stop due to dehydration. Some bacteria have mechanisms to survive in a dormant state until conditions become favorable for growth and reproduction again. However, prolonged drying can lead to cell death and the inability for the bacteria to revive.
Do bacteria make their own food or find food?
It depends on the type. Most bacteria must obtain nourishment but some are capable of photosynthesis.
How do bacteria cause an illness as food poisoning?
Food pisoning is most often caused by toxic substances that bacteria found in food produce. The bacteria have grown and multiplied in the food, most often if the food is stored at a certain temperature that must not be too low or too high. The toxins are sometimes produced when the bacteria grow and multiply in the food before eating it. Other times the bacteria produce the toxins when they grow and multiply further inside the stomach and intestines after the food has been eaten.
