What’s Really in Your Food? How Local Retailers Are Prioritising Safety

Would you still eat your favourite snack if you didn’t know what was in it?

Food safety isn’t just a matter of regulations – it’s a matter of trust. South African consumers expect transparency from the brands they support, and leading retailers like Woolworths know this. As shoppers become increasingly mindful of health and sustainability, the demand for rigorous food testing has never been higher.

Behind the scenes, laboratories like Microchem – supported by Chemetrix – are working tirelessly to ensure that what’s on your plate meets the highest standards of safety and quality.

The challenge facing South Africa’s retailers

In an age of global food supply chains and growing health concerns, food testing is no longer a “nice-to-have” – it’s essential.

Local retailers face mounting pressure to uphold not only national safety standards but also consumer expectations around integrity, traceability and clean labels.

For quality-driven retailers like Woolworths, the challenge lies in ensuring that food is tested accurately and efficiently, with results that can be trusted. From imported fruit and vegetables to locally produced meat and dairy, every product must be analysed for contaminants, residues and adulterants before reaching the shelves.

When ‘safe’ isn’t simple: The complex nature of food testing

Food safety testing involves identifying and quantifying chemical residues such as pesticides, mycotoxins, additives, allergens, and heavy metals. In particular, volatile organic compounds (VOCs) and environmental pollutants such as dioxins or plasticisers are increasingly under scrutiny.

The complexity of modern food products and their varied matrices – from fatty snacks to fibrous grains – presents analytical challenges that demand robust, high-sensitivity instruments. Traditional methods may struggle with accuracy, throughput, or regulatory compliance, especially when laboratories are expected to produce results quickly and cost-effectively.

Identify the unknowns

One of the most significant breakthroughs in food testing is non-targeted screening, which allows labs to detect unknown or unexpected contaminants without having to pre-select specific compounds.

The Agilent 7250 GC/Q-TOF, available through Chemetrix, is purpose-built for this. It pairs high-resolution gas chromatography with time-of-flight mass spectrometry, enabling analysts to confidently identify trace compounds in complex food samples.

With this level of insight, labs like Microchem can test for a broader range of contaminants with exceptional clarity and speed. Whether it’s detecting pesticide residues in leafy greens or verifying additive levels in processed snacks, the 7250 GC/Q-TOF allows for greater coverage – and fewer blind spots.

Stay fast, focused and compliant

For routine, high-throughput testing where speed and accuracy are vital, the Agilent 5977C GC/MSD remains the gold standard. This system excels at targeted analysis of known contaminants such as preservatives, residual solvents, and food packaging migration chemicals.

Its robust performance, low detection limits and smart functionality make it ideal for commercial labs needing reliable results under tight deadlines. In Microchem’s case, the 5977C allows for cost-efficient testing at scale – from raw materials to final packaging – without compromising quality or regulatory compliance.

At Chemetrix, we help our clients integrate instruments like the 5977C seamlessly into their workflows, providing technical support, training and ongoing guidance to keep things running smoothly.
