Reheating leftovers is a quick fix for busy nights, but there’s one simple step most people skip that could make you seriously sick. According to food safety experts, failing to stir your food when microwaving can allow harmful bacteria like Salmonella, E. coli, Listeria, and Campylobacter to survive and thrive.
“Microwaves don’t heat evenly,” explains Dr. Jill Roberts, a microbiologist at the University of South Florida. “That’s why stirring is critical. It helps distribute heat and moisture, which allows all parts of your food to reach the magic number: 165˚F—the temperature needed to kill dangerous microbes.”
Even a delicious casserole, lasagna, or bowl of leftover rice can become a bacteria breeding ground if not reheated properly. Foods rich in protein—especially eggs, seafood, meats, and starches like potatoes and pasta—are especially risky. Thick sauces and layered dishes can hide cold spots, even if the top feels hot.
Jason Reese, a food safety expert, warns: “It’s like playing roulette if you’re not heating evenly.” And it’s not just about the microwave. Improper food storage adds to the danger. Leftovers should be refrigerated within two hours and tossed after four days.
To stay safe, follow these three steps:
- Wash your hands thoroughly before handling food.
- Stir halfway through microwaving to break up cold spots.
- Use a food thermometer to ensure that all parts reach a temperature of 165˚F.
Don’t let a quick meal become a long night of regret. Stir it, heat it right, and eat with peace of mind. Safe reheating isn’t just smart—it could save your stomach.
