Not so fast, cowboy. Cooking kills most pathogens—salmonella, listeria, and our pal E. coli—but it doesn’t kill boredom or bad jokes. However, some bacteria produce heat-stable toxins that survive even a nuclear blast in your oven. Ever had food poisoning that hit you faster than a microwave dinner? That’s the toxins, not the live bugs.

So, yes, cooking kills the E. coli itself—making it safe—but if you left that chicken out for four hours in the sun, the toxins it produced are already there. Heat doesn’t reverse time, folks. It only stops the time machine from crashing. Moral: don’t cook spoiled food; cook fresh food that’s had a boring life on a shelf.
Surprising Fact: You’re Probably Eating E. coli Right Now
Don’t panic—but your salad might be a bacterial rave. Leafy greens, sprouts, and unpasteurized apple juice are common carriers. One study found that 4% of spinach samples tested positive for E. coli—that’s like finding a cockroach in every 25 salads. The good news? Washing with cold water removes only about 99% of bacteria, but the remaining 1% is still a tiny army.
Cooking kills E. coli on veggies, too. Blanch that broccoli! Roast those Brussels sprouts! If you’re eating a raw salad, you’re basically playing Russian roulette with a salad spinner. For most people with healthy immune systems, it’s fine—but for pregnant women, kids, or your grumpy uncle with a weak stomach, cook it or skip it.
