For instance, bacteria like Campylobacter and Salmonella can survive in refrigerated temperatures for extended periods. To effectively combat bacterial growth, it’s essential to combine refrigeration with other tactics, such as proper handling, storage, and cooking techniques. Additionally, it’s crucial to ensure that the refrigerator is set at a consistent temperature of 40°F (4°C) or below to create an environment that’s hostile to bacterial growth. With these precautions in place, you can significantly reduce the risk of bacterial contamination and keep your food safe for consumption.

Can freezing food prolong its shelf life?

Freezing food is one of the most effective methods to significantly prolong its shelf life. By lowering the temperature, freezing inhibits bacterial growth and slows down enzymatic activity, which is what causes food to spoil. This process is beneficial for both extended food storage and reducing food waste. For instance, meat can last up to a year in the freezer, while fruits and vegetables can retain their nutrients and freshness for several months. To ensure optimal results, it’s essential to prepare food for freezing correctly: portion it out in airtight containers or freezer bags, label everything with dates, and maintain a consistent freezer temperature of 0°F (-18°C). Additionally, don’t forget to allow frozen foods to thaw properly in the refrigerator to minimize the risk of bacterial growth before cooking or consuming. By understanding and applying these best practices, you can fully harness the power of freezing to keep your food fresh and reduce waste.
