What is the main risk of improper food storage?

Improper food storage primarily increases the risk of foodborne illnesses. When food is not stored at the correct temperatures or in appropriate conditions, harmful bacteria, viruses, and parasites can thrive, leading to contamination. This poses a significant health risk to consumers, as these pathogens can cause serious health issues when ingested.

Additionally, when food is not stored correctly, factors such as time and temperature abuse can accelerate the growth of spoilage organisms and pathogens. Thus, effective food storage practices are essential in preventing the occurrence of these illnesses, ensuring food safety, and protecting public health.

The other options do not address the critical health risk associated with improper food storage. Increased food quality and improved shelf life would typically result from proper storage, while higher costs are influenced by various factors beyond just storage practices. These points highlight the importance of maintaining food safety through proper storage methods, with a clear focus on preventing foodborne illnesses.
