Most of the food we buy in supermarkets is loaded with preservatives, artificial colours, flavour enhancers, and other additives. The main purpose is simple: keep the product looking “fresh” and shelf-stable for weeks or even months. Without these chemicals, many fruits, vegetables, meats, breads, and ready meals would spoil quickly, look unappealing, or lose texture and taste long before they reach our tables.
Manufacturers and retailers insist the food is safe, claiming all additives are approved and tested, and that produce is “not sprayed with poison.” Yet many consumers no longer trust these assurances. There is a widespread feeling that the fruit and vegetables we buy are not truly clean.Why the distrust exists:
- Produce is often treated with post-harvest fungicides, waxes, and ripening inhibitors to extend shelf life and prevent mould or bruising during transport and storage.
- Residues from pre-harvest pesticides can remain on skins or be absorbed into the flesh, even after washing.
- “Fresh” labels on packaged salads, cut fruit, and pre-prepared meals usually mean the product has been heavily processed and treated with preservatives or modified atmosphere packaging to slow spoilage.
- Long-distance supply chains mean most supermarket produce is days or weeks old by the time it reaches the shelf, so chemicals are essential to maintain appearance and prevent waste.
GMO seeds (genetically modified organisms, or GMOs) are indeed one of the most controversial topics in South African agriculture – especially now in 2026, with recent court rulings, field trials, and ongoing debates. There are so many different views that it's hard to form a clear opinion.
Based on the current situation in South Africa (the only country in Africa with widespread commercial GMO adoption for more than 25 years).
The result is a paradox: food looks perfect and stays “fresh” far longer than nature allows, but many people feel it is far from natural or truly healthy. The saying “if it lasts too long without spoiling, something is probably wrong” has become a common sentiment.While regulations exist and maximum residue limits are set, the cumulative effect of multiple low-level exposures (from different foods and additives) remains poorly understood. Growing numbers of consumers are turning to local farmers’ markets, organic options, or growing their own food to regain trust and control over what they eat.
Since you can’t speak to the real decision-makers in person, the label (and the ingredients list) is the closest thing you have to “confronting” the company. That’s why reading labels carefully is one of the most powerful things an individual can do:
- Look for preservatives (e.g., sodium benzoate, potassium sorbate, nitrates/nitrites, BHA/BHT, sulphur dioxide).
- Watch for ultra-processed markers (e.g., modified starch, hydrolysed protein, high-fructose corn syrup, artificial colours/flavours).
- Check “best before” vs “use by” dates—many products are safe past “best before” but companies use short dates to reduce returns/complaints.
Meat in South African supermarkets remains safe to eat during the current FMD outbreak. FMD does not affect human health or make meat unsafe for consumption - The meat on supermarket shelves is safe to eat — the higher price is mainly due to real supply chain problems caused by FMD, not because the meat itself is unsafe or “poisoned.” That said, consumers are right to be frustrated with rising costs and to ask questions about transparency in the supply chain.If you’re concerned about affordability or ethics, buying directly from local butchers, farmers’ markets, or known trusted suppliers can sometimes give better value and more certainty during times like this. But from a food safety standpoint, supermarket meat is not a health risk right now.
Most people who buy food in supermarkets never get to speak to the people actually responsible for what goes into the products. The workers on the floor (cashiers, shelf stockers, managers) usually have zero say in ingredients, preservatives, sourcing, or labelling decisions. They’re just doing their job and often trust the packaging the same way customers do.
