Keeping food safe in your fridge

Refrigerate leftovers within two hours of cooking. And there's no need to wait for piping-hot foods to cool down before storing them―modern refrigerators can handle the heat. "Throw away all perishable foods that have been left in room temperature for more than two hours (one hour if the temperature is over 90°F, such as at an outdoor picnic during summer)," says the USDA on its website.
