Refrigerated transport is a form of climate-controlled transportation which is planned to maintain a cool or frozen temperature, depending on the product being transported. The development of refrigerated transport was a key step in the development of modern food safety, because this form of transport ensures that foods stay at safe temperatures as they are shipped, and refrigerated transport has a number of other uses, from medicine to physics. Many shipping companies offer this type of transport for an additional cost, and some companies really specialize in refrigerated transport.

Many people have busy in the crudest form of refrigerated transport, which involves packing the temperature-sensitive product into a cooler or case with ice packs, dry ice, or loose ice. The ice keeps the temperature cold during shipping for a length of time which can differ from a few hours to a few days. This type of refrigerated transport can be used to move a small amount of a material, such as soft drinks for a picnic or biological samples from the site of an epidemic.

On a big scale, refrigerated transport requires a refrigerated vehicle. Refrigerated trucks, train cars, and cargo holds use huge compressors and refrigeration equipment to maintain a constant temperature which can be adjusted to accommodate specific products. For instance, some vaccines need to be shipped at very cold temperatures, while produce may simply need to be kept below ambient temperatures so that it does not ripen too quickly or become rotten.
