Final answer:
Refrigerating potentially hazardous foods is crucial to inhibit bacterial growth, maintain safety and freshness, and prevent foodborne illnesses by slowing down the spoilage process and keeping foods out of the temperature danger zone.
Step-by-step explanation:
The reason for refrigerating potentially hazardous foods is to inhibit bacterial growth and prevent foodborne illnesses. Refrigeration slows down microbial metabolism and controls the growth of microorganisms which can cause food spoilage and diseases. Maintaining a refrigerator temperature at or below 4 degrees C (40 degrees F) and a freezer temperature below 18 degrees C (0 degrees F) ensures that food is stored safely. Thawing foods should be done in the refrigerator, microwave, cool water, or during cooking, but never at room temperature as it can activate harmful microbes.
Refrigeration also works to maintain the safety and freshness of food by slowing down the processes that cause it to spoil. It also prevents changes in the food's color, flavor, or texture, delays rancidity, and maintains nutritional value. Using a thermometer to monitor the internal temperatures of food is crucial to ensure that it is safe to consume.
Failure to control temperature can lead to the rapid multiplication of microorganisms, especially in the danger zone between 4 and 60 degrees C (40 and 140 degrees F). Foods left in this range for more than two hours may pose risks of foodborne illness due to rapid bacterial growth.
