Do germs prefer hot or cold temperature?

Germs, or microorganisms, vary in their temperature preferences depending on the species. Some bacteria thrive in warmer temperatures, typically between 30°C to 40°C (86°F to 104°F), which is why they often proliferate in food left at room temperature. Conversely, some germs can also survive and adapt to cold environments, but their growth is generally slower at lower temperatures. Overall, warmth tends to favor the growth of many harmful bacteria.
