The Cold Chain Gap Between Export Fruit and Township Tables

Published: February 2026

In the United States, the American Frozen Food Institute recently launched a campaign called “Fresh Thinking About Frozen,” built around a simple premise: the freezer is not a place of last resort — it is a tool for eating well in real life. The campaign cites statistics showing that families who keep frozen produce on hand tend to eat more fruits and vegetables overall. Pre-portioned frozen meals help with portion control. Frozen berries are ready for morning smoothies. The message is warm, encouraging, and assumes something so basic it never needs stating: that the family has a working freezer.

In South Africa, that assumption breaks everything.

The same idea — that frozen food is a tool for nutrition, budget management, and food waste reduction — is not just valid here. It is arguably more important. South Africa wastes 10.3 million tonnes of edible food annually, equivalent to 45% of the country’s available food supply. Over 63% of South African households experience some level of food insecurity. The economics of buying in bulk, preserving food through freezing, and reducing the frequency of expensive transport-dependent shopping trips are not lifestyle optimisations — they are survival strategies.

But between the port where R1 billion in export fruit sits waiting for a berth and the township household where a mother decides whether she can afford to buy a week’s worth of protein at once, there is a cold chain gap that no amount of industry investment at the commercial end can close. This article examines that gap — the last link in South Africa’s cold chain — and the emerging technologies, business models, and policy responses that could begin to bridge it.

The Appliance Divide: Who Has a Freezer and What Kind

South Africa’s Census 2022 reported that refrigerator and freezer ownership increased from 53.8% in 2001 to 83.2% in 2022. The International Institute of Refrigeration estimates that approximately 85% of South African households now own a refrigerator, with total stock estimated at around 14 million units as of 2016 and growing steadily since. By 2040, projections suggest around 27.8 million refrigerators will be in South African homes.

These headline figures suggest the problem is largely solved.

They are misleading.

The 83% national average masks enormous variation by income, geography, and dwelling type. Ownership of large appliances shows steep increases as household income rises, with the gap widening significantly for dedicated chest freezers versus basic fridge-freezer combinations. A household in Sandton with a 400-litre chest freezer in the garage and a double-door fridge-freezer in the kitchen operates in a fundamentally different cold chain reality than a household in Diepsloot with a 15-year-old bar fridge running on prepaid electricity.

The quality dimension matters as much as the ownership dimension. Many low-income households own refrigerators that are old, energy-inefficient, and equipped with freezer compartments too small to store meaningful quantities of frozen food. The tiny freezer box in a standard single-door fridge — typically 30 to 50 litres — can hold ice and perhaps a bag of frozen vegetables. It cannot hold a bulk-purchased month’s worth of chicken portions, the kind of purchasing strategy that makes economic sense for families operating on tight budgets.

Energy costs compound the problem. Eskom tariffs have increased by approximately 747% since 2007/2008. For households on prepaid electricity — the dominant payment model in townships and informal settlements — every rand spent keeping an old, inefficient fridge running is a rand not available for food. The perverse result is that the appliance meant to preserve food competes directly with the food budget it is supposed to protect.

And then there is the 17% — roughly 3 million households — that have no refrigeration at all. For these families, the entire concept of “fresh thinking about frozen” is meaningless. They buy daily, from whatever is closest and cheapest, because they have no way to store perishable food safely for more than a few hours.

Load Shedding: The Crisis That Broke Trust in the Freezer

The prolonged load shedding crisis of 2022-2023, which saw South Africa endure unprecedented Stage 6 power cuts — sometimes losing electricity for 10 to 12 hours daily — did more than spoil food. It fundamentally damaged the relationship between South African households and their freezers.

The physics are straightforward. A well-stocked chest freezer, if kept closed, can maintain safe temperatures for approximately 24 to 48 hours during a power outage. A half-empty upright freezer might manage 12 to 24 hours. But load shedding at Stage 4 and above was not a single outage — it was a pattern of repeated temperature cycles, with the compressor unable to fully recover cold temperatures before the next scheduled blackout began. Under these conditions, the freezer became a liability rather than an asset.

Families who had invested in bulk purchasing — exactly the strategy that “Fresh Thinking About Frozen” promotes — found themselves watching hundreds of rands worth of meat and vegetables thaw, refreeze, and eventually become unsafe. The financial and emotional cost was real. Media reports from the peak of the crisis documented families disposing of freezer contents they could not afford to replace, effectively losing a month’s worth of food investment in a single weekend.

Although load shedding has substantially improved since late 2024, the behavioural impact persists. Households that were burned by the experience have reverted to daily or near-daily purchasing patterns. They buy what they will eat today. They do not trust the freezer with a week’s worth of protein. The rational economic calculus — that bulk buying frozen food saves money — has been overridden by the lived experience that the power can go out at any time and take your investment with it.

This trust deficit is not irrational. It is a perfectly reasonable response to unreliable infrastructure. And it represents a hidden cost of the load shedding crisis that rarely appears in economic analyses: the permanent shift away from efficient food purchasing and storage behaviour among millions of households.

The Spaza Shop: South Africa’s Last-Mile Cold Chain Challenge

If the household freezer represents the endpoint of the cold chain, the spaza shop represents its last commercial link — and it is a link under enormous stress.

South Africa has over 150,000 spaza shops, informal micro-convenience stores that originated during apartheid when historically disadvantaged individuals were restricted from owning formal businesses. These shops add approximately R120 billion annually to the local economy, and together with other forms of traditional trade, contribute 35% of total grocery sales in the country. The informal sector accounts for an estimated 30% to 40% of South Africa’s annual food expenditure, representing a market value of about R178 billion.

For millions of South Africans living in townships, the spaza shop is not a choice — it is the primary food source. Shopping malls are distant, taxi rides are expensive, and the daily logistics of purchasing food from formal retail are prohibitive for households without private transport. The spaza shop is where the last link of the cold chain either holds or breaks.

And in most cases, it breaks.

The vast majority of spaza shops operate with minimal or no cold chain infrastructure. Some have a single chest freezer for frozen goods. Many have nothing. Fresh produce, dairy, and meat products are stored at ambient temperature, sold quickly, or lost to spoilage. The temperature gap between the wholesale market and the spaza shelf — the exact gap that Dr Ikechukwu Opara’s research at Stellenbosch University identified as the primary driver of wholesale food waste — is replicated thousands of times daily across every township in the country.

The consequences became tragically visible in 2024 when a series of food-borne illness incidents linked to spaza shops killed 22 children and caused over 890 reported cases of illness. While the contamination was linked to pesticides and organophosphates in products rather than temperature abuse specifically, the crisis exposed the fundamental lack of food safety infrastructure in the informal retail sector. The government’s response — requiring all spaza shops to register with their local municipalities within 21 days and allocating R500 million to the Spaza Shop Support Programme — explicitly identified cold storage as a priority infrastructure need.

The Mail & Guardian analysis of the spaza sector identified the core challenge: these shops face regulatory hurdles, supply chain inefficiencies, and limited access to affordable, high-quality stock. The government funding programme specifically calls for grants, loans, and infrastructure support for cold storage, secure premises, and renovations. But the scale of the challenge — 150,000 shops, most operating without formal registration until the 2024 crackdown — means that any solution must be affordable, scalable, and suited to the realities of informal commerce.

The Economics of Frozen for Low-Income South Africa

The American frozen food campaign makes the economic case straightforwardly: eight in ten consumers agree that buying frozen helps reduce food waste at home, translating to savings of roughly $1,500 per household per year.

In South Africa, the economics are more compelling but also more constrained.

Consider a township household with four members, earning R8,000 per month — roughly the median household income in many urban townships. Food expenditure typically consumes 30% to 40% of income. That household spends approximately R2,400 to R3,200 per month on food.

• The daily buying trap: Without adequate freezer capacity, this household buys food daily or near-daily from the nearest source — often a spaza shop with limited stock and higher unit prices. A 2kg bag of frozen chicken portions costs approximately R80 at a supermarket. The same quantity purchased as individual portions from a spaza shop over a week might cost R120 or more. Multiply that across all protein, produce, and staple purchases, and the daily-buying household pays a poverty premium of 20% to 40% on food — not because they are making poor choices, but because they lack the cold storage to make better ones.
• The transport cost multiplier: A trip to a formal retail outlet means a taxi fare — typically R20 to R40 return — plus the time cost. For a household without a car, the economics of a weekly supermarket trip only work if the savings on bulk purchase exceed the transport cost. This is precisely the calculation that adequate freezer capacity enables: buy more, less often, at lower unit prices, and store the surplus frozen.
• The waste reduction dividend: The CSIR estimates that consumer-level food waste accounts for 18% of South Africa’s total food waste, costing households approximately R21.7 billion annually. For low-income households, the waste rate on fresh produce is directly related to storage capacity. Without refrigeration, tomatoes, spinach, and milk must be consumed the day they are purchased or discarded. A functioning freezer transforms the calculus — leftovers become future meals, bulk-purchased vegetables are blanched and frozen, and the daily urgency of perishable consumption disappears.

The arithmetic is clear. The barrier is not information or motivation — it is infrastructure.

Solutions: What Is Emerging to Close the Gap

The gap between South Africa’s commercial cold chain and its household and community cold chain is not waiting for a single breakthrough solution. Multiple approaches are emerging simultaneously, addressing different segments of the problem at different price points.

Solar-Powered Household Refrigeration

South Africa receives an average of 2,500 hours of sunshine annually — among the highest solar irradiance levels globally. Johannesburg alone averages 3,182 sunshine hours per year. This abundance makes solar-powered refrigeration not merely viable but economically compelling, particularly when set against Eskom’s 747% tariff increase since 2007/2008.

Defy Solar Off-Grid Range: South Africa’s largest domestic appliance manufacturer, Defy (a subsidiary of Turkey’s Arçelik), launched its Solar Off-Grid fridge and freezer range in March 2024 — the first product of its kind in the South African market. The range includes both an upright fridge-freezer (303L, A+ energy rated) and a chest freezer (254L, A energy rated) that operate entirely off-grid through integrated solar panel and lithium-ion battery systems.

The technology is significant for several reasons. The units come with a Smart Control Box that manages power source switching — solar during the day, battery at night — without requiring a separate inverter or home solar installation. The chest freezer features a Multimode Control that allows the unit to function as a fridge, chiller, or freezer depending on the user’s needs. Battery backup provides up to three days of operation without solar input.

Trade, Industry and Competition Minister Ebrahim Patel described the launch as a “milestone event” that meets national objectives for localisation, job creation (Defy employs approximately 2,500 workers across South Africa), and climate goals. Defy CEO Mustafa Soylu framed it as the “first step in demonstrating that solar is the more future-fit solution to better energy on the African continent.”

The system requires a 550W solar panel for inland areas or 700W for coastal regions, plus a lithium-ion battery — both purchased separately. At current retail prices of approximately R10,500 for the fridge-freezer unit, the total system cost (unit plus panel plus battery) places it firmly in the mid-market range, more accessible than a full home solar installation but still beyond the reach of the lowest-income households.

Zero Appliances Solar Range: Zero Appliances, based in Kempton Park, Johannesburg, offers a range of DC-powered solar chest freezers and fridge-freezers designed for off-grid use. The Zero 200L Solar Chest Freezer operates on 12V or 24V battery systems, requires a 250W solar panel, and reaches temperatures of -18°C to +7°C. The unit runs directly from battery power via a solar controller, eliminating the need for an AC inverter and the associated 15% efficiency loss.

Zero also produces gas/electric hybrid models — chest freezers that can run on LPG gas, mains electricity, or solar — providing triple redundancy against power interruptions. For a country that has experienced both load shedding and gas supply disruptions, this multi-fuel flexibility has practical value that single-source appliances cannot match.

Broader Market: Retailers like Sustainable.co.za now carry dedicated solar-ready fridge and freezer collections, and specialist suppliers such as Gas & Solar Appliances offer complete off-grid refrigeration packages. The Defy Greenline 150L Solar Chest Freezer, priced from around R6,050, represents an entry point for smaller households or micro-businesses. The market is developing rapidly, with options ranging from compact 100L units suitable for spaza shops to 300L+ models for households doing serious bulk food storage.

Containerised Solar Cold Storage for Communities

The household solution addresses individual families, but the spaza shop and community market problem requires a different scale of intervention. This is where containerised solar-powered cold storage — proven in Nigeria and Kenya — offers a compelling model for South African adaptation.

The ColdHubs Model: Nigeria-based ColdHubs has deployed a network of solar-powered walk-in cold rooms at markets and farm clusters across Nigeria. Each ColdHub is a 10-foot-square (approximately 3m × 3m) solar-powered cold storage unit capable of keeping produce fresh for up to 21 days. The model operates on a pay-as-you-store subscription — farmers and traders pay a daily flat fee for each crate stored. No grid connection is required. The units are designed for installation at major food production and consumption centres.

ColdHubs CEO Nnaemeka Ikegwuonu won the $1.5 million AYuTe Africa Challenge for the technology. The model directly addresses the wholesale market waste that Dr Opara’s research identified: by providing cold storage at the point of sale, the temperature gap between arrival and consumption is closed without requiring every individual trader to invest in their own refrigeration.

SokoFresh in Kenya: Nairobi-based SokoFresh, supported by the Global Energy Alliance for People and Planet, provides smallholder farmers with solar-powered, off-grid mobile cold storage facilities comprising solar panels, sensors, a condensing unit, and an evaporator maintaining 4°C to 15°C. The units operate on a cooling-as-a-service model — farmers rent cold storage capacity on a short or long-term basis, even in very remote areas, with real-time temperature monitoring via mobile devices.

The South African Opportunity: Neither ColdHubs nor SokoFresh currently operates in South Africa, but the model is directly applicable — and arguably more commercially viable given South Africa’s more developed infrastructure, higher solar irradiance, and established supply chain networks. A containerised solar cold storage unit deployed at a major township fresh produce market or positioned adjacent to a cluster of spaza shops could serve as a shared cold chain node, enabling multiple small businesses to store perishable goods properly without each requiring individual refrigeration investment.

The concept aligns directly with the R500 million Spaza Shop Support Programme’s infrastructure objectives. Rather than subsidising individual freezer purchases for 150,000 shops — a logistically impossible task — a containerised community cold storage approach could serve clusters of 20 to 50 spaza shops from a single installation. The pay-as-you-store model removes the capital barrier entirely, converting cold chain access from an asset ownership problem into an operational expense.

A practical configuration for a South African township deployment might include a standard 6-metre shipping container fitted with solar panels (4 to 6kW array), battery storage for overnight operation, insulated panels, and a commercial compressor system maintaining multiple temperature zones (-18°C for frozen goods, 2°C to 8°C for fresh produce). Total installed cost would likely range from R250,000 to R400,000 — substantial, but amortised across 30 to 50 subscribing businesses, the per-user cost drops to levels comparable with municipal service fees.

Retail-Led Approaches

Major retailers are not waiting for government or NGO-led solutions.

• Shoprite’s Usave eKasi: Shoprite has been accelerating the rollout of its Usave eKasi container stores in townships — small-format outlets (100m² to 200m²) built from converted shipping containers, positioned directly in communities that lack formal retail access. These units include commercial refrigeration and freezer sections, bringing cold chain infrastructure into areas previously served only by unrefrigerated spaza shops. The format is significantly smaller than a standard Shoprite, but significantly larger and better equipped than a traditional spaza shop, creating a bridge between formal retail cold chain standards and township commercial reality.
• Pick n Pay’s Spaza Partnerships: Pick n Pay has partnered with independent traders to upgrade existing spaza shops, providing access to supply chains, training, and in some cases, refrigeration equipment. The model preserves local ownership while professionalising operations — addressing the food safety concerns that drove the 2024 registration crackdown without displacing community-based businesses.

Technology-Enabled Supply Chain Integration

Startups are attacking the supply chain inefficiencies that make cold chain access expensive for informal traders.

• Yebo Fresh (Smollan Group) connects brands and retailers in township markets through a technology platform integrating data analytics, logistics optimisation, and market intelligence gathered by field teams. By aggregating demand from multiple spaza shops and coordinating deliveries, the platform reduces the per-unit cost of cold chain distribution to informal retail points.
• Zande provides logistical and financial support to spaza shops, cutting out middlemen by enabling direct bulk purchases from manufacturers with last-mile delivery via its driver programme. By centralising procurement and distribution, Zande enables small shops to access the same bulk pricing that makes frozen food economically viable for large retailers — the missing piece in the “buy frozen, save money” equation.
• Shopit offers a mobile app that allows spaza shop owners to compare wholesaler prices, place orders, and receive deliveries directly to their storefronts — with inventory control and business intelligence features that help small operators manage perishable stock more effectively.

What Needs to Happen

Closing the gap between South Africa’s commercial cold chain and its household cold chain requires action across multiple fronts simultaneously.

• Subsidised solar refrigeration for food-insecure households. The government’s existing solar energy incentives — including the Section 12B tax deduction for solar panels — do not extend to solar-powered appliances. A targeted programme providing subsidised or financed solar freezers to qualifying low-income households would directly address food waste, nutrition, and energy resilience simultaneously. The Defy Solar Off-Grid range and Zero Appliances solar freezers are manufactured or assembled in South Africa, meaning subsidies would also support local employment.
• Community cold storage infrastructure at scale. The R500 million Spaza Shop Support Programme should prioritise containerised solar cold storage deployments at major township commercial nodes rather than fragmented individual appliance grants. The ColdHubs pay-as-you-store model provides a proven, scalable template that generates ongoing revenue to cover maintenance and operations — unlike one-off equipment grants that deteriorate without maintenance budgets.
• Cold chain training integrated with spaza registration. The mandatory spaza shop registration process creates an opportunity to embed cold chain training — safe food storage temperatures, FIFO stock rotation, cold chain monitoring basics — into the compliance framework. This addresses the human capacity gap that technology alone cannot solve.
• Energy-resilient refrigeration as a food security priority. National food security policy should recognise household refrigeration as critical infrastructure, not a consumer discretionary purchase. The connection between refrigerator ownership, dietary diversity, and child health outcomes is established in the research literature — a study across 66 low- and middle-income countries found that children in households with a refrigerator had measurably greater height-for-age scores, indicating better nutrition outcomes.
• Data collection on the household cold chain. South Africa tracks commercial cold storage capacity but has almost no systematic data on household refrigeration quality, freezer capacity, or the relationship between cold chain access and food purchasing behaviour in low-income communities. The CSIR, Stats SA, and academic institutions should incorporate cold chain access metrics into household surveys to build the evidence base for targeted interventions.

The Freezer as Equaliser

The American frozen food campaign’s tagline — “The freezer isn’t a place of last resort. It’s a tool for eating well in real life” — contains a truth that transcends its comfortable suburban context. In South Africa, where food costs consume a third of low-income household budgets, where 45% of the food supply is wasted before it reaches consumers, and where 63% of households experience food insecurity, the freezer is not a lifestyle upgrade. It is infrastructure.

Infrastructure for nutrition. Infrastructure for economic efficiency. Infrastructure for food safety.

And in a country blessed with among the highest solar irradiance on the planet, infrastructure that no longer needs to depend on a grid that has proven it cannot be depended upon.

South Africa’s cold chain industry invests billions in commercial refrigeration — cold rooms, reefer containers, temperature-controlled transport fleets. That investment is essential. But the most expensive cold chain in the world is worthless if it ends at the supermarket loading dock while 3 million households have no way to keep food cold and 150,000 spaza shops operate without temperature control.

The last link in the cold chain is not a reefer container or a cold room. It is the freezer in the kitchen — or the one that should be there but is not. Closing that gap is not a consumer appliance problem. It is a food security imperative.
