Detailed explanation-1: -Cold storage Temperature is the most important factor influencing bacterial growth. Pathogenic bacteria do not grow well in temperatures under 3 °C (38 °F). Therefore, meat should be stored at temperatures that are as cold as possible. Refrigerated storage is the most common method of meat preservation.
Detailed explanation-2: -The “Danger Zone” (40 °F-140 °F) Bacteria grow most rapidly in the range of temperatures between 40 ° and 140 °F, doubling in number in as little as 20 minutes.
Detailed explanation-3: -Bacteria are all around us, including those that can cause food poisoning. Food poisoning bacteria grow best at temperatures between 5°C and 60°C. This is called the Temperature Danger Zone. Keeping potentially hazardous foods cold (below 5°C) or hot (above 60°C) stops the bacteria from growing.
Detailed explanation-4: -Leaving food out too long at room temperature can cause bacteria (such as Staphylococcus aureus, Salmonella Enteritidis, Escherichia coli O157:H7, and Campylobacter) to grow to dangerous levels that can cause illness.
