What temperature is too cold for bacteria?

Cold temperatures (below 40°F) can significantly slow down bacterial growth, but only heat (above 140°F) can destroy bacteria.

Why do hospitals keep it so cold?

Bacteria Growth Prevention Bacteria thrive in warm environments, so hospitals combat this with cold temperatures, which help slow bacterial and viral growth. This is no different than food safety practices in the food industry that rely on refrigeration to keep food from growing harmful bacteria.
