All food contains bacteria and mold spores, and most food contains insect eggs. Given the right environment, these microorganisms will start to grow and destroy the food. The main conditions that can cause insects and microorganisms to grow are moisture and heat.

If products are not properly packaged, they can absorb moisture out of the air. When the moisture reaches a level of 12% to 18%, product breakdown will accelerate. Make sure to store food in a dry place.

Heat is also a major cause of deterioration in food quality. Store all products away from heat ducts, clothes dryers, sunlight, chimneys and other sources of heat.
