You’ve heard about antibiotic-resistant bacteria, right? The superbugs that laugh at your pills? Well, heat still works on them. Resistance is a chemical game, not a physical one. You can’t evolve a force field against a fire.
That being said, some bacteria form spores—like tiny, armored time capsules. Think Clostridium botulinum (the stuff that causes botulism). These spores survive boiling. To kill them, you need a pressure cooker that hits 250°F (121°C). Regular heat just makes them take a nap.

Your Fridge Doesn’t Care About Your Feelings
Here’s the ironic twist: heat kills them, but cold just slows them down. Bacteria don’t freeze to death; they just hibernate. That’s why leftovers in the fridge can still go bad after a week—some cold-loving psychopaths, like Listeria, actually thrive at 40°F.
So if you’re relying on a cold fridge to save you, remember: you’re just buying time, not winning the war. Heat is the final statement.
