What could result from not properly storing food items?

Not properly storing food items can lead to pest infestations and foodborne illness. When food is not stored at the correct temperatures or in a sanitary manner, it creates an environment conducive to the growth of harmful bacteria. These microorganisms can contaminate food, leading to gastrointestinal illnesses when consumed. Additionally, improperly stored food can attract pests such as rodents and insects, which can further contaminate the food supply and pose additional health risks.

In contrast to the correct answer, options such as increased food flavor, reduction in food waste, and better food presentation are unlikely outcomes of poor storage practices. Flavor may not improve and could even diminish due to spoilage, food waste could actually increase if food becomes spoiled, and presentation can be negatively affected if food items are damaged or contaminated.
