When it comes to food safety, proper storage is crucial to prevent the growth of harmful bacteria and reduce the risk of foodborne illnesses. Perishable foods, such as meat, dairy products, and cooked leftovers, should be stored in the refrigerator to keep them fresh and safe to consume. However, there are instances when perishable foods are left out of the refrigerator, whether it’s because of forgetfulness or unforeseen circumstances. So, how long can perishable food be out of the refrigerator before it becomes unsafe to eat?
The general rule of thumb is that perishable foods should not be left at room temperature for more than two hours. This timeframe is based on the temperature danger zone, which is between 40°F (4°C) and 140°F (60°C). Within this temperature range, bacteria multiply rapidly, increasing the risk of foodborne illnesses. Therefore, it’s important to minimize the time perishable foods spend in the temperature danger zone.
