What Makes Food Go Bad Faster?
Several things can make your food spoil quicker than you'd like:
- Temperature: If your fridge is warmer than 37-40°F (3-4°C), you're asking for trouble. Keep it cool.
- Moisture: Too much humidity can turn your food into a moldy mess. Use airtight containers to keep things dry.
- Air: Oxygen is a sneaky culprit that causes oxidation and spoilage. Seal your food tightly.
- Cross-Contamination: Mixing raw and cooked foods is a recipe for disaster. Keep them separate to avoid contamination.
