Heat exposure, temperature changes, and real-time monitoring are some of the notable cold chain concerns in perishables logistics.
FREMONT, CA: Cold chain logistics primarily comprises transporting and storing perishable items at controlled temperatures to maintain their quality and safety. This intricate supply chain ensures that all kinds of perishable foods, including fresh fruits and vegetables, dairy, meat, and seafood, are delivered to consumers in optimal condition. The cold chain for perishable commodities is divided into stages, beginning with post-harvest handling, processing, and packaging and ending with transportation, warehousing, and distribution.

Aside from its importance, the cold chain faces several challenges that may impact its efficiency. One significant challenge is keeping the temperature consistent throughout the supply chain. Food deterioration and waste may occur if the temperature is set incorrectly. Retailers must overcome the cold chain logistics and transportation challenges that are crucial for the food industry to decrease waste, assure food safety, and meet customer demand for high-quality perishables.
Significant cold chain challenges in perishables logistics are elaborated below:
Heat exposure: When temperature-sensitive commodities are loaded and unloaded, they risk losing their integrity due to prolonged heat exposure. These stages are crucial because they expose the items to external influences, causing temperature changes.
Real-time monitoring: A reefer container requires constant, real-time temperature monitoring to protect perishable items. Data loggers and temperature sensors provide up-to-date information about the environment while in transit. This enables logistics organizations to quickly respond if temperatures climb above or beyond the acceptable limit. The company may transfer the shipment to another cold storage facility in such cases.
Infrastructure deficiency: More than 90 percent of the cold chain logistics industry is unstandardized, privately owned, and fragmented. There are no equipped cold storage facilities that can handle a specific material, reducing its quality. Reefer vehicles are unsuitable for loading perishables and are prone to breakdowns, resulting in significant supply chain losses.
Variations in temperature: The greatest challenge in cold chain logistics is maintaining a consistent temperature range. If temperatures fluctuate during shipment, fresh vegetables, fruits, seafood, and poultry products are susceptible to damage. Because these products are perishable, severe deterioration may occur due to inclement weather or unexpected delays.
Absence of visibility: The lack of visibility and transparency can seriously threaten cold chain logistics. One should be aware of the location and condition of the perishables as they progress through numerous stages and involve multiple stakeholders.
