A recent investigative report has unveiled widespread pesticide contamination in common foods sold across South African supermarkets, raising urgent red flags about food safety and the vulnerability of children to hazardous chemicals. The briefing titled “What’s really in our food?” was released on June 11, 2026, by the African Centre for Biodiversity (ACB), an independent research and advocacy organisation . The findings, based on independent testing conducted by a South African National Accreditation System (SANAS)-accredited laboratory, have ignited serious public health concerns, revealing a significant gap between the reality of daily dietary exposure and the country’s current regulatory framework .
The study analyzed 43 everyday food products purchased between November 2025 and January 2026, including staples such as maize meal, wheat flour, bread, breakfast cereals, fruits, vegetables, tea, peanut butter, and infant foods . The results are alarming: 86% of the products tested contained at least one detectable pesticide residue . Across the entire sample set, researchers identified 37 different pesticide active ingredients, with many products containing multiple residues . In a particularly concerning case, a single popular tomato sauce product, All Gold Tomato Sauce, contained a cocktail of 14 distinct pesticide residues .
The investigation highlights a critical failure in how pesticide exposure is regulated. Current systems assess pesticides one by one and crop by crop, failing to account for the “cocktail effect” of cumulative and aggregate exposure . In reality, people consume mixtures of pesticides daily through various foods. This overlap compounds exposure with each meal, a risk that is especially pronounced for children . Because children eat more food relative to their body weight and are in critical stages of development, they bear a disproportionate burden . The report starkly illustrates this, noting that from maize and wheat products alone, a child could already reach nearly 23% of the acceptable daily intake for Malathion and 14% for Dichlorvos before consuming any other foods . An expert report prepared for the South African government has linked prenatal exposure to such pesticides with cognitive deficits, including impacts on learning, memory, and neurodevelopment .
Of particular grave concern is the contamination of foods intended for infants and toddlers. Seven of the nine baby food products tested contained at least one pesticide residue, including substances classified internationally as highly hazardous pesticides (HHPs) . Products such as Nestlé Cerelac Wheat, Purity Cream of Maize, and Nido Baby Milk Powder were found to contain pesticides like malathion, glyphosate, imidacloprid, and piperonyl butoxide . The detection of 13 highly hazardous pesticides on 26 occasions across various foods, including those marketed for children, underscores the profound risk . The briefing also noted that 13 product-pesticide combinations exceeded at least one applicable regulatory benchmark, whether from South African limits, Codex standards, or more stringent EU limits . In some instances, such as with Malathion, the South African maximum residue limit (MRL) was found to be up to 160 times higher than the Codex standard, raising questions about whether compliance equates to meaningful consumer protection .
The ACB argues that these findings expose profound weaknesses in South Africa’s pesticide regulatory system, including limited monitoring, inadequate transparency, outdated legislation, and fragmented oversight . The organisation is not alleging unlawful conduct by food producers but is calling for urgent, evidence-based regulatory reforms to protect public health . Zakiyya Ismail, the ACB’s Pesticide Coordinator and lead author of the briefing, stated the findings are “disheartening” and highlight that current standards do not routinely assess how people are exposed through real-world diets . The recommendations include establishing stronger child-protective residue standards, phasing out highly hazardous pesticides where safer alternatives exist, and incorporating aggregate and cumulative risk assessments into routine regulatory practice . The organisation is also calling for greater transparency through public access to monitoring data, a plea that echoes concerns raised earlier in 2026 when the ACB formally requested the deregistration and ban of glyphosate after finding it in baby cereal and other staples .
