Refrigeration (cold storage) is a common food preservation practice for thermally sensitive products. Most scientific and government organizations recommend that a temperature of 40°F or lower should be maintained in the refrigerated vehicle during distribution of foods to ensure quality. Improper controls cause an estimated loss of 1.2% to 1.5% of foods at the grocer level, amounting to a loss of close to $2 billion. Customers such as those in the cold storage industry have a cold chain they need to protect. So, how can you understand each vehicle’s location and its compliance with temperature control objectives?
