What can happen if foods are stored improperly?

When foods are stored improperly, a range of problematic consequences can arise, which makes the option that encompasses all of these potential issues the most comprehensive and accurate choice.

Firstly, foods may lose their nutritional value over time if not stored properly. Factors such as exposure to light, heat, and air can degrade important vitamins and minerals, making the food less beneficial for health.

Secondly, improper storage can also lead to pest attraction. Foods that are not kept in well-sealed containers can draw in insects and rodents, which can contaminate the food and create further health issues.

Lastly, perhaps the most concerning consequence of improper food storage is that foods can become hazardous to health. This can occur through the growth of bacteria, molds, and other pathogens in environments that are too warm or moist, leading to foodborne illnesses.

Therefore, the correct answer acknowledges that improper storage can lead to a loss of nutritional value, attract pests, and create health hazards, making it all-encompassing and indicative of the serious implications of food storage practices.
