Is it safe to put hot food directly into the refrigerator?
Yes, it is generally safe to put hot food directly into the refrigerator; however, there are some important guidelines to follow. According to the USDA, it is recommended to cool the food down as quickly as possible to prevent the growth of bacteria. Hot foods can raise the temperature inside the refrigerator, potentially putting other stored food at risk.
To help mitigate this risk, consider dividing large amounts of hot food into smaller, shallow containers. This allows the food to cool more rapidly and ensures it reaches a safe temperature before being stored long-term. Additionally, it is a good practice to leave space in the refrigerator to ensure proper air circulation.
What temperature should food be cooled to before refrigerating?
Food should be cooled to a temperature of 40°F (4°C) or below before being placed in the refrigerator. This temperature is crucial in preventing the growth of harmful bacteria that can thrive in warmer conditions. The USDA recommends cooling foods to this temperature within two hours of cooking to minimize any food safety risks.
To effectively cool food, try placing your hot dish in a cold water bath or using an ice bath if the portion size allows. Stirring the food occasionally can also help distribute heat evenly and promote faster cooling. Once the food reaches the appropriate temperature, it can then be safely stored in the refrigerator.
How long can hot food sit out before refrigeration?
Hot food should not be left out at room temperature for more than two hours. If the ambient temperature is above 90°F (32°C), this time is reduced to just one hour. The reason for this is that bacteria can multiply rapidly when food is within the “danger zone,” which is between 40°F and 140°F (4°C and 60°C).
To ensure food safety, always be aware of the time that food has been cooling on the counter. If you notice that food has been left out for longer than the recommended time, it’s best to discard it to avoid the risk of foodborne illness.
