Here’s a fun fact: the longer you heat food, the more bacteria die. It’s not an instant zap—it’s a slow burn. For example, at 140°F, it might take 10 minutes to kill most bacteria; at 165°F, it’s seconds.
You can imagine bacteria as tiny, stubborn campers. A quick campfire (like a flash fry) might scare some away, but a long, steady campfire (like a slow roast) will toast them all.

This is why sous vide cooking is so popular. It holds food at a precise low heat for hours, killing bacteria without overcooking your steak. Science, meet dinner.
What About the Microwave?
Microwaves are sneaky. They heat unevenly, so cold spots in your food can leave bacteria alive. That’s why you should stir and rotate your bowl—like you’re giving the heat a map.
A microwaved burrito might feel hot on the outside but be chilly in the middle. That’s a bacterial VIP lounge. Always check the internal temp with a thermometer—it’s your food’s secret agent.
And no, those “kill bacteria” buttons on your microwave aren’t magic. They’re just timers. Gotta do the work yourself.
