What happens if you don’t refrigerate cooked food?
If cooked food is not refrigerated, it can become a breeding ground for harmful bacteria. When food is left at room temperature, especially between 40°F and 140°F (the danger zone), bacteria can multiply rapidly. Symptoms of foodborne illness can range from stomach cramps to more severe issues, depending on the type of bacteria or toxin present. Because certain types of bacteria, like Staphylococcus aureus and Clostridium botulinum, thrive in unrefrigerated environments, it is crucial to avoid leaving cooked food out for extended periods.
In many cases, food should not be left out for more than two hours. This timeframe decreases to just one hour in warmer conditions, such as during hot summer months. To ensure safety, any cooked food you plan to store should be cooled to room temperature before refrigerating it. However, if there are doubts about the safety of the food after being left out, it is best to err on the side of caution and discard it.
How long can cooked food sit out before it needs to be refrigerated?
Cooked food should ideally not remain at room temperature for more than two hours. This timeframe drops to just one hour if the surrounding temperature exceeds 90°F. Within this safety limit, bacteria like Salmonella and E. coli can double in number every 20 minutes, leading to an increased risk of foodborne illness. Foods that contain meat, dairy, or seafood particularly require quick refrigeration due to their perishable nature.
