At 37°F, bacteria throw their tiny hands up in defeat. They grow very slowly at that temperature, which means your leftovers survive longer than your last Tinder date. The FDA officially recommends keeping your fridge at or below 40°F, but 37°F is the superhero target.
If your fridge runs at 35°F, you’re not a hero—you’re just chilling your eggs to iceberg status. And if it’s 42°F? Congratulations, you’re running a petri dish with a light bulb. Surprising fact: every 5°F increase doubles the bacterial growth rate. Yes, doubles. That’s exponential math you don’t want on your deli meat.
