You've eaten all you can possibly eat at Thanksgiving dinner, and there's still plenty of food left. It's a problem so common that experts have linked holiday leftovers to a seasonal increase in food poisoning cases.
The Centers for Disease Control and Prevention reports that outbreaks of a bacteria that causes food poisoning occur most often in November and December. Many of those outbreaks have been linked to common holiday foods such as turkey and roast beef. And while for many people food poisoning is a short-lived discomfort, for vulnerable members of your family such as the young or the elderly it could be life-threatening.
If stored in a refrigerator, leftovers can stay good for three to four days. If they're stored in a freezer, it's three to four months. It's best to label the food with an expiration date when you put it away, to help you keep track of when it's no longer safe to eat.
