Refrigeration is an essential part of food safety, helping to slow down the growth of bacteria and keep our food fresh for longer periods. However, it’s not enough to simply put food in the fridge; it needs to be kept at the right temperature to ensure its safety and quality. So, how cold does food need to be refrigerated?
The general rule is that perishable foods, such as raw meat, poultry, seafood, dairy products, and cooked leftovers, should be stored at a temperature below 5°C (40°F). This low temperature slows down the growth of bacteria, reducing the risk of foodborne illnesses.
While refrigeration can prolong the shelf life of food, it’s important to note that it doesn’t completely stop bacteria from multiplying. Therefore, it’s crucial to consume refrigerated foods within a certain timeframe to ensure their safety. The USDA recommends consuming most perishable foods within 3 to 4 days.
It’s also worth noting that not all foods need to be refrigerated. Certain fruits and vegetables, for example, can be stored at room temperature. However, it’s important to keep them away from direct sunlight and sources of heat to prevent spoilage.
