How can food be kept safe during transportation?

The correct choice emphasizes the importance of using appropriate temperature controls and secure packaging when transporting food. This is crucial for maintaining food safety, as certain foods need to be kept at specific temperatures to prevent bacterial growth and spoilage. For example, perishable items like meat, dairy, and prepared foods must be kept at safe temperatures to minimize the risk of foodborne illnesses.

Additionally, secure packaging helps prevent contamination from external sources, protects the food from physical damage, and ensures that the integrity of the product is maintained throughout the transportation process. This includes using insulated containers for hot or cold items, as well as effective sealing to avoid leaks or exposure to contaminants.

The other options do not adequately address the crucial elements of food safety during transportation. Distributing food in bulk without refrigeration poses significant risks for temperature-sensitive items. Frequently varying transportation routes does not inherently contribute to food safety and may even disrupt the conditions needed for safe transport. Lastly, while limiting employee handling can reduce contamination risks, it does not cover all aspects of food safety related to temperature control and packaging, which are fundamental in preventing food safety hazards during transportation.
