Under what condition should food be stored in a refrigerator to prevent spoilage?

Food should be stored in a refrigerator at temperatures below 40 degrees F to prevent spoilage. This temperature limit is critical because it slows down the growth of most bacteria and pathogens that can lead to foodborne illnesses and spoilage. Refrigeration at or below this temperature range inhibits microbial growth, thus significantly extending the shelf life of perishable foods.

Storing food at temperatures above 40 degrees F increases the risk of bacteria multiplying rapidly, leading to potential food spoilage and safety issues. The ideal refrigeration temperature helps ensure that food remains safe for consumption while maintaining its quality.
