Final answer:
Methods for cooling potentially hazardous foods include ice water bath, refrigeration, and freezing.
Step-by-step explanation:
There are several methods for cooling potentially hazardous foods. One common method is rapidly cooling the food by placing it in an ice water bath. This helps to bring down the temperature quickly and prevent bacterial growth. Another method is refrigeration, which slows down microbial growth. Freezing is another effective method, as it stops microbial growth and can even kill susceptible organisms.
