Often when people cook for the Thanksgiving holiday, there are likely to be plenty of leftovers.
While leftovers can be a great way to extend the meal and save time, it’s crucial to handle them
safely to avoid foodborne illness. To ensure that leftovers are safe to eat, several key practices
must be followed.
Firstly, it’s important that the food is cooked to a safe internal temperature. For example, turkey
should reach an internal temperature of 165°F to kill harmful bacteria. To avoid cross-
contamination, use a food thermometer to check the temperature in the thickest part of the meat.
Once the food is cooked, hot food must be kept at a temperature of at least 140°F or warmer until
it is served. Keeping food at this temperature helps prevent bacteria from growing, which can
multiply quickly at unsafe temperatures.
After the meal is over, the key to safely storing leftovers is refrigerating them promptly.
Leftovers should be refrigerated within two hours of being taken off the heat source, and if the
room temperature is above 90°F (such as at an outdoor gathering), they should be refrigerated
within one hour. Bacteria grow rapidly between the temperatures of 40°F and 140°F, which is
known as the "danger zone." If food is left in this range for too long, harmful bacteria can
multiply to dangerous levels.
The two primary causes of foodborne illness are cooking food at an unsafe temperature and
leaving food out for longer than two hours. Bacteria, viruses, parasites, or toxins in contaminated
food or beverages can cause foodborne illness. Symptoms of foodborne illness can range from
mild stomach upset to severe conditions requiring medical attention, so it’s important to avoid
the risks by adhering to food safety guidelines.
When storing leftovers, make sure to place them in shallow containers to allow for quick
cooling. The refrigerator should be set at 40°F or lower to ensure the safe storage of perishable
foods. If you plan to keep leftovers for more than a few days, freezing them is another option to
extend their shelf life. Additionally, be sure to reheat leftovers to a safe temperature of 165°F
before consuming them.
Safe handling of leftovers is particularly important in reducing the risk of foodborne illness, not
just during the holiday season but throughout the year. By following these simple
steps—cooking food to the right temperature, refrigerating leftovers promptly, and reheating
them properly—you can help ensure that your Thanksgiving leftovers remain safe to enjoy.
