1. Understanding Food Storage Safety
Knowing how long food stays safe in the refrigerator is crucial for preventing foodborne illnesses and reducing food waste. Proper food handling and storage are essential practices to maintain food safety and quality. Let’s explore the key principles of safe food storage.
1.1. The Importance of Proper Refrigeration
Refrigeration slows bacterial growth, which is why keeping food at the right temperature is essential. Bacteria multiply rapidly at room temperature, but refrigeration slows this process significantly. According to the USDA, the ideal refrigerator temperature is at or below 40°F (4°C).
1.2. Understanding Expiration Dates
Expiration dates on food packaging can be confusing. They often indicate peak quality, not safety.
- “Sell By”: Tells the store how long to display the product for sale. You should buy the product before this date.
- “Use By”: The manufacturer recommends using the product by this date for best quality.
- “Best If Used By (or Before)”: Indicates when the product will have the best flavor or quality. It is not a safety date.
1.3. The Danger Zone
The “danger zone” is the temperature range between 40°F (4°C) and 140°F (60°C) where bacteria grow most rapidly. Foods should not be left in this temperature range for more than two hours. If the temperature is above 90°F (32°C), food should not be left out for more than one hour.
