Which of the following is crucial for food safety regarding pest prevention?

Properly sealing food items is essential for pest prevention and overall food safety. When food is sealed correctly, it creates a barrier that helps keep pests such as insects and rodents from accessing the food. Many pests are attracted to food sources, and if they can penetrate packaging, they may contaminate the food or cause spoilage.

By using airtight containers and secure packaging, food handlers can significantly reduce the risk of pests infiltrating the food supply. Additionally, sealed food helps maintain quality and freshness, which are important aspects of food safety.

In contrast, options related to cross-contamination, leaving food out for extended periods, and storing food at room temperature do not contribute to pest prevention and can actually increase the risk of foodborne illnesses and spoilage.
