Explanation:
Detailed explanation-1: -Between 0°C and −18°C (or 0°F and 32°F), most bacterial will survive but not grow.
Detailed explanation-2: -Freezing delays spoilage and keeps foods safe by preventing microorganisms from growing and by slowing down the enzyme activity that causes food to spoil. As the water in the food freezes into ice crystals, it becomes unavailable to those microorganisms that need it for growth.
Detailed explanation-3: -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.
