E. coli slows down in the cold. Your refrigerator is like a cryogenic prison for these bacteria. They can survive, but they can’t multiply. Keep your fridge below 40°F (4°C). If you’re not sure, buy a fridge thermometer. It’s cheaper than a doctor’s visit.
Here’s a wild fact: Freezing does not kill E. coli. It just puts them in a coma. The moment they thaw out, they wake up grumpy and ready to party. So don’t rely on your freezer alone. Heat them up. Make them suffer.
