Association of Air and Refrigeration:
Vaccines are highly sensitive biological substances, whose condition and effectiveness become compromised over time and they are especially affected by exposure to heat (in some cases, at low temperatures), sunlight and fluorescent lights.
Once they lose their properties, these vaccines become irrecoverable, so it is essential that distribution, storage and administration processes are carried out under controlled temperatures.
The cold chain must ensure that vaccines, from manufacture through to immunization of the patient, are maintained at the required temperatures. The following table shows the stages of the cold chain with the general temperature recommendations given by the World Health Organization (WHO).
-National Airport: Facilities for Product Storage in transit (2 ° to 8 ° C)
-Primary vaccine storage: Cold storage (2 ° to 8 ° C) and freezing chamber (-15 ° to -25 ° C)
Intermediate vaccine storage: cold room (2 ° to 8 ° C) and freezing chamber (-15 ° to -25 ° C)
Intermediate vaccine storage: Refrigerators (2 ° to 8 ° C) and freezers (-15 ° to -25 ° C)
Health-Center: Refrigerators (2 ° to 8 ° C) and cold packs
-Health Post: Refrigerators (2 ° to 8 ° C) and cold packs or transport of vaccines

Guidelines have been released for the proper treatment of frozen products at all stages of the logistics chain.
From the publication "Recommendations for Logistics Frozen Products, Frozen and Ice Cream, AECOC"
Technical as well as sanitary controls for food and food products that typically require freezing temperatures for preservation and alteration must be extended to the operations of the entire supply chain so that from the origin to the final time of consumption the product keeps its inherent qualities.
There are no situations where there is room for improvisation and, although the limits vary in flexibility, logistics applied to cold chains leave no room for error.
The complexity of cold chain logistics
It's not news that one of the determining factors in logistical planning is based on the profile of the goods: dangerous, general or perishable.
The infrastructure that has been installed ensures that agricultural products are processed competitively and with high levels of quality in regard to their preservation.
Vice Minister of Foreign Trade of Panama, Jose Pacheco, stressed during his visit to facilities of the company Galores, who specializes in cold storage, that multinational corporations see Panama as the best option in terms of logistics because of the Panama Canal, the Hub of the Americas and port facilities. "
An industrial facility dedicated to cold storage of food products.
More precisely, we define a Refrigerated Warehouse as an industrial complex comprising premises, facilities and equipment permanently or temporarily dedicated to storing refrigerated food and may constitute in itself an autonomous refrigeration industry, be annexed to another larger center or have annexs to its activity.
