Refrigeration slows bacterial growth. Bacteria exist everywhere in nature, including
in the foods we eat. When bacteria have nutrients (food), moisture, and favorable temperatures, they grow rapidly, increasing in numbers to the point where some types of bacteria can cause illness. Bacteria grow most rapidly in the range of temperatures between 41°F and 140 °F (the "Danger Zone"), some doubling in number in as little as 20 minutes. A refrigerator set at 41°F or below will protect most foods.
Hence it is very essential to maintain the temperature below 41 degree Fahrenheit. This hinders the multiplicity of the micro organism. In most cases, even if the food is affected with pathogenic bacteria, it could not be detected. It would not give any kind of indication of infection. There is no other option but to prevent before it comes.
Commercial Fridges plays an important role in helping to be healthy. It is important to keep the refrigerators clean and safe and they must be serviced at least once in a year. Dust settlement is not allowed and the users must ensure that enough fresh air flows into the condenser. There should be a proper aeration service for the exhaust air to escape. This is the reason for keeping low temperature in Air Conditioners. They use special filters and prevent the entry of bacteria. Even if they are present, they cannot sustain for a longer period of time as they do not have favorable conditions. The importance of refrigerators is more and hence they are the need of the hour to stay healthy. One must remember that "Health is Wealth".
