IN the current shortage of tomatoes, one warning is getting louder — reports that some producers may be using chemicals associated with inducing early ripening in other crops to accelerate the process in tomatoes.
If true, the health implications may easily go beyond taste and price.
Accelerated ripening can mean uncontrolled residue profiles, inconsistent maturity development, and increased likelihood of using substances outside approved agricultural inputs for tomatoes.
Even when a chemical is known and used elsewhere for another crop, applying it to a different commodity changes the safety equation.
This is not merely a food supply issue and neither is it just a problem of scarcity. It is fast exposing gaps across the entire supply chain—from suspected phytosanitary bleaches as some traders reportedly smuggle the crop from neighbouring countries to chemical controls amid reports of some local farmers using chemicals to fast-track ripening.
And while traders are exploiting the imbalance between supply and demand to charge atrocious prices, the alleged use of unsanctioned chemicals becomes harder to detect leaving consumers to be used as the final testing ground.
While it is a public secret that Zimbabwe’s tomato market has just entered a volatile phase in which a basic staple suddenly feels rare — not because the crop is impossible to grow, but because supply, oversight, and market discipline appear to have broken down at the same time.
This comes as reports from consumers, traders, and observers point to a situation where local availability has thinned out dramatically, driving up prices to levels described as punishing.
When demand remains steady while supply collapses, markets often respond with price increases.
The unfolding tomato shortage narrative looks less like a normal supply-and-demand adjustment but more like a compounded crisis involving importing pressures, uneven enforcement, and potential food-safety risks.
At the centre of the issue is a supply gap.
Whether the shortfall is connected to seasonal factors, disruptions affecting local production, poor storage and distribution efficiency, or damage along the value chain, the outcome is the same: fewer tomatoes reach shelves than the public needs.
In a functioning market, this scarcity should trigger a predictable response—fresh production should be scaled up where possible, imports should be regulated properly, and quality standards should be enforced.
Instead, the market is increasingly characterised by opportunism and uncertainty.
Traders who have tomatoes are charging far above normal rates, while consumers — especially those without flexibility in budgets — face difficult choices between affordability and access to healthy food.
“I guess this is a wake-up call for the country to explore ways of sustainably producing tomatoes during the winter season to ensure supplies are not disrupted at any point like what is happening at the moment.
“We are saying farmers can even form cooperatives or groups to jointly produce the crop with the sole hope of bridging this gap that has seen consumers suffering at the mercy of unscrupulous traders.
This is presenting an opportunity of our village business units (VBUs) to scale up production of the crop, especially in controlled environments like greenhouses and make sure markets do not face deficits,” my old friend and market analyst, Dr Charles Dhewa commented recently.
It is during stressful moments like these that consumers need transparent information to understand the factors driving the shortages — production issues, transport disruptions, verified import volumes, and confirmed inspection outcomes, which allows them to contextualise the elevated prices.
It is unfortunate that when consumers receive conflicting signals or none at all, they will allow their suspicions to fill the gap.
The current tomato situation is being interpreted by many as not just a shortage, but a shortage that benefits a limited group with inventory control.
The tomato shortage is often described in economic terms—the missing product and rising prices.
But the deeper story is about control and safety.
When markets run out of tomatoes, price gouging becomes more likely. When imports move through mixed legal and illegal routes, quality verification weakens.
When phytosanitary enforcement is poor, compromised produce can enter with fewer barriers.
And when there are allegations of undocumented chemical use to force early ripening, the crisis extends into public health territory.
If the country is to find a durable solution to this problem of tomato shortages that seems to be fast becoming a perennial thing, it is necessary to treat the current situation as not merely as a temporary supply shock, but as a diagnostic test of its food safety, enforcement, and market integrity.
The long and short of this line of argument is that the challenge of tomato shortages during winter is not a new thing but something that the agriculture sector does not seem to take seriously and prepare for it.
There should be concerted efforts from all value chain actors to pull up all stops so that winter production of the crop is treated differently from all other seasons.
Remember, winter has many disadvantages for farmers, which start from high production costs to physical factors.
This means that stakeholders need to find ways of going round this low productivity problem and ensure the supply chain is not disrupted.
On the one hand, imports should be treated as a temporary and stop-gap measure whose adoption must not pose any kind of threat to both consumers and local farmers.
Imports can reduce shortages quickly, but only if done through regulated systems that include documentation, inspections, and phytosanitary checks.
In theory, legal importation ensures that goods meet minimum quality and safety requirements before entering local markets.
However, it is also important to appreciate the fact that not all imported tomatoes may be passing through fully documented processes.
When trade routes include both legal and illegal movement, the risk profile changes dramatically.
Undocumented or informally handled consignments are harder to trace.
That makes it more difficult for regulators to identify where problems begin—whether at the farm, during shipment, at border points, or at wholesale markets.
Even when tomatoes arrive, their history may be hard to confirm: temperature exposure during transit, storage conditions, packaging integrity, and the timing of inspections all influence quality and shelf life.
Tomatoes are perishable – delays and poor handling can lead to spoilage, microbial growth, and accelerated deterioration.
In other words, the issue is not only whether tomatoes arrive, but how they arrive and how long they survive on shelves.
Additionally, if the tomato imports elude official entry points, they also miss the phytosanitary scrutiny needed to prevent the introduction and spread of pests and plant diseases.
Phytosanitary checks serve the broader role of quality gatekeeping mechanisms and when they are inconsistent, the system becomes porous—creating room for contaminated produce and undermining consumer confidence.
When all is said and done, it is the legitimate farmers and importers who are adversely affected by poor phytosanitary enforcement.
They often face higher costs—inspection fees, compliance overhead, and time delays.
And when illegal routes succeed, they are punished through competitive disadvantages, encouraging wider system deterioration.
In the current difficult times, local farmers may be forced to harvest under pressure to meet demand and capture high prices.
But harvest timing is constrained by biology.
Tomatoes cannot simply be “produced faster” without affecting maturity and shelf life.
If farmers release immature tomatoes into the market that is suddenly overwhelmed—or if new supplies flood in at once from other sources—they risk selling product that ripens unevenly, spoils quickly, or fails to meet consumer expectations.
When such a thing happens, local farmers may end up receiving lower returns than expected.
If they oversupply immature product, they may be left absorbing losses through price reductions, rejects, or unsold stock.
That is why balancing harvest timing, storage, and market forecasting is vital—not only for farmer income, but for stable retail availability that protects consumers.
