What is happens to food poisoning bacteria at temp below 5c?

At temperatures below 5°C, the growth of food poisoning bacteria is significantly slowed down or halted, as most pathogenic bacteria thrive in warmer conditions. While some bacteria can survive at low temperatures, their metabolic activity is greatly reduced, which minimizes the risk of foodborne illness. However, it's important to note that freezing does not kill all bacteria; it merely puts them in a dormant state, and they can become active again once the temperature rises. Proper refrigeration is key to maintaining food safety.
