So does having refrigerated trucks end all worries related to chilled courier service? Well, not entirely!
For instance, urban areas that generally have a warm climate throughout, creates more problems for frozen food distribution. One best example to explain such scenario is the case of Singapore. Although the country has a modest temperature, it has, however, a high humidity and dry foods when exposed to high humid areas lead to the decaying of food. Also, there are high chances of contamination if effective measures are not taken to save the food from being exposed to the hot outside even for a second.
As a result, frozen parcel needs to be moved in a way that they are not exposed to the hot temperatures outside. Transporters need to be very precise with their handling and delivery in order to ensure a contamination-free transportation.
