South African tomato quality suffers due to poor roads, temperature issues
As trade becomes more complex, the linkages between production, logistics, and pricing are tightening.
SOUTH AFRICA – Poor road conditions and inconsistent temperature control have degraded the quality of South African tomatoes, even as major producer ZZ2 maintains strong yields.
The country produced just under 528,000 tons of tomatoes in 2023, with a five-year average of around 540,000 tons, with Limpopo accounting for more than 60% of the national output.
Research by the University of KwaZulu-Natal’s Post-Harvest Innovation Centre found that transport on rural roads is the main cause of damage, leading to bruising, structural damage, and exposure to non-optimal temperatures.
Optimal storage and transport conditions range from 12°C to 15°C. Lower temperatures can cause chilling injury, while higher temperatures accelerate ripening and decay.
A ZZ2 spokesperson emphasized the importance of supply chain management. “Maintaining quality after harvest is just as important as how the crop is produced. Once tomatoes leave the field, temperature control, packaging and transport conditions determine whether they arrive at market in a premium condition or suffer losses that affect shelf life and price.”
The sector employs between 25,000 and 28,000 people each year, with tomatoes accounting for about 24% of total vegetable production, second only to potatoes.
In addition, large-scale producers dominate, led by ZZ2, which plants between 2,000 and 2,500 hectares each year and accounts for more than 30% of national production.
Further, the study found that tomatoes transported in large bins ripened more quickly and sustained greater damage than those in cartons. Therefore, interventions such as harvesting at the correct maturity, using smaller containers, refrigeration, and improved driving practices can reduce losses.
These post-harvest innovations offer high ROI for regional investors, as improved packaging and consistent cold-chain monitoring directly reduce downgrading and price pressure.
RSA Group CEO Jaco Oosthuizen said tomatoes with bruising or uneven ripeness are downgraded. “In weeks of high supply, even small quality defects can translate into significant price pressure for producers.”
As trade becomes more complex, the linkages between production, logistics, and pricing are tightening. For South African producers, performance depends on both yield and the ability to maintain quality throughout the supply chain.
These infrastructure gaps, including poor rural roads and inadequate cold storage near production zones, threaten export potential, even as major producers like ZZ2 maintain strong yields.
Interventions focused on temperature regulation, improved packaging, and driver training offer the most direct path to reducing losses and stabilizing returns across the tomato value chain.
