Cold Chain and Storage for Perishables in Africa (2026)

Fresh tomatoes, peppers, leafy vegetables, fruit, fish and dairy can lose value within hours if they sit in the heat. This guide to cold chain and storage for perishables in Africa explains, in plain language, what a cold chain is, which handling steps protect quality before you even reach a cold room, how to store grain and dry goods so they stay sound, and how to think about power and shared facilities. It draws on FAO publications, avoids cost figures because prices depend on location and equipment, and does not give medical or nutrition advice. Check food safety rules for your product with your national regulator (information as of October 2026).

What a cold chain is

FAO describes a cold chain as a temperature-controlled system that keeps perishable goods in good condition from production to consumption. On its page about cooling the chain, it splits the chain into an upstream part, which covers on-farm pre-cooling, storage and packing, and a downstream part, which covers refrigerated transport, market storage and retail. For a farm near Kaduna selling tomatoes to traders in Lagos, that means every step from the field to the market stall matters, not only the cold room.

In a 2022 report on sustainable food cold chains, FAO makes a point that applies to small producers too: providing cooling technology alone is not enough, and a whole-system approach is needed. The report describes a project in Nigeria that installed ColdHubs, and says such projects are still the exception rather than the norm. You can read FAO's announcement of the report.

Handle produce right before it reaches the cold room

FAO's manual for the preparation and sale of fruits and vegetables says that controlling temperature is one of the main tools for extending postharvest life, because low temperatures slow metabolism and microbial activity. It also makes several practical points:

• Remove field heat quickly. Precooling removes heat from the harvested crop before storage or transport. Refrigeration equipment alone cannot do this fast enough for highly perishable produce, and the manual says room cooling takes at least 24 hours while forced-air cooling is considerably faster.
• Respect chilling injury. Tropical and subtropical crops can be damaged by temperatures that are too low, and the manual says the injury is cumulative. Colder is not always better.
• Control humidity. Water loss means loss of fresh weight, and the manual says most fruits and vegetables need high relative humidity, while crops such as onion, garlic and pumpkin do better with much lower humidity.
• Allow air to move. Package ventilation openings should be large enough, and tight loads trap heat and gases. Stacking and packing patterns matter.
• Keep incompatible crops apart. The manual advises against storing ethylene-producing produce with ethylene-sensitive crops, since mixing can cause premature ripening, yellowing and sprouting.
• Avoid mixed loads in transport, which cause incompatibility problems because packages of different sizes do not stack or vent well.

The manual is available from FAO's website. Use it as a source of principles, then ask a local horticulture or food technology adviser for the temperature and humidity that suit your crop and your equipment.

Power and shared facilities

Many producers face unreliable electricity, which is a risk for any cold room. FAO says decentralised solar solutions can play a critical role in enabling reliable cold chains in off-grid areas, and that photovoltaic systems can power on-farm cold storage, pre-cooling units and refrigerated containers, alone or together with batteries or backup generators. We cannot say which option suits your location or budget. Costs vary by location, scale and equipment, so ask suppliers for quotations and compare more than one.

If a full cold room is out of reach, consider these lower-cost steps first:

1. Harvest at cooler times of day and keep produce in the shade.
2. Use clean, ventilated crates rather than sacks that crush the produce.
3. Reduce the time between harvest and sale or processing.
4. Ask whether a shared or rented cold storage facility operates near your market or processing area, for example in Kano, Kumasi or Nairobi.
5. Consider processing surplus into a more stable product, such as dried goods or paste, if your regulator allows it and you are registered.

Storing grain, pulses and dry goods

Not everything needs refrigeration. For maize, rice, beans and similar products, the main enemies are moisture, heat, insects and mould. An FAO document on safe grain storage says that either or both temperature and moisture must be reduced to create a conducive environment for storage, that cleaning storage facilities before and after storage is part of sanitation, and that storage conditions should be checked regularly by inspection. It adds that cooling slows insect pests. A 2015 article on the FAO food loss platform about hermetic storage bags notes that grain must be dry before hermetic storage because wet grain can mould. Read the FAO storage requirements and talk to your agricultural extension service about drying and storage that suit your crop.

Mould and aflatoxin are a particular concern for maize and groundnuts, so read our guide on aflatoxin and food safety testing.

Build a simple cold chain plan

1. Map your losses. Walk the route from field to buyer and note where product is damaged, delayed or left in the sun.
2. Fix the cheapest steps first. Shade, crates, timing and cleaning cost far less than equipment.
3. Measure temperature. Use a thermometer in storage and vehicles, and keep a simple log.
4. Plan for power cuts. Decide in advance what you will do if the cold room stops.
5. Tell buyers your handling conditions. A buyer who knows how you store and transport produce is more likely to trust your quality.

If you sell perishables or grain in volume, our guide to selling farm produce in bulk shows how storage links to buyer expectations. Cold chain and storage records also support the food safety documents buyers ask for. See our guide to HACCP and ISO 22000 for African food manufacturers.

Frequently asked questions

What is a cold chain? According to FAO, it is a temperature-controlled system that preserves perishable goods from production to consumption, with upstream and downstream stages.

Do small farms need a cold room? Not always at first. Shade, quick harvesting, ventilated crates and short delivery times can reduce losses. A cold room helps when you hold perishable produce for longer.

Is colder always better for tropical produce? No. FAO's manual says chilling injury is a concern for tropical and subtropical crops and that the damage is cumulative.

Can I power a cold room with solar? FAO says solar photovoltaic systems can power on-farm cold storage, alone or with batteries or backup generators. Ask installers about sizing and costs for your site.

How do I store grain safely? Dry it, clean the store, protect it from insects and check it regularly, as FAO's storage guidance describes.
