You open the fridge and grab an apple that's been sitting there all week — still crisp, still perfect. Meanwhile, the apple you left on the counter yesterday is already getting soft and sad. What's the fridge doing that your kitchen counter can't?

When they find something they like — a strawberry, a slice of cheese, yesterday's pizza — they start eating and multiplying. One bacterium becomes two, two become four, four become millions. That's what we call spoiling: it's a microscopic feeding frenzy.
