                                According to the U.S. Department of Agriculture (USDA), harmful bacteria can multiply rapidly in perishable foods left between 40°F and 140°F. While a refrigerator slows this growth, it doesn't stop it entirely, meaning that most leftover foods should be consumed or frozen long before they reach the one-week mark.
