Amidst South Africa’s proud legacy of maize production, the Eastern Cape finds itself confronting a hidden peril lurking within its staple crop. Mycotoxins, toxic fungal compounds notorious for their detrimental health effects, are silently threatening the region’s maize supply.
Despite historical significance in mycotoxin research, Eastern Cape farmers are facing a critical gap in monitoring, leaving their maize unchecked for contamination. This oversight raises alarms not only for food safety but also for the integrity of South Africa’s maize industry.
As concerns mount, urgent action is demanded to fortify regulatory measures and safeguard both public health and agricultural prosperity in the Eastern Cape. Food For Mzansi spoke to Neriman Yilmaz, senior research fellow at Forestry and Agricultural Biotechnology Institute (FABI) at the University of Pretoria (UP), who dived into a study that explains the types of mycotoxins lurking in Eastern Cape crops.
Octavia Spandiel: What are mycotoxins and how severe is it in the Eastern Cape; is there a threat to food security?
Neriman Yilmaz: Mycotoxins is produced by fungi, are toxic compounds found in various crops, including maize. While over 400 mycotoxins exist, only a few are globally regulated. Fumonisins and Ochratoxin A, discovered in South Africa, are among them.
South Africans, particularly in province like the Eastern Cape, heavily rely on maize, consuming up to 1 – 2kg per person per day. Despite mycotoxin regulations covering the entire country, the Eastern Cape’s maize is not analysed in annual reports due to its minimal contribution to the gross domestic product.
Contaminated maize due to poor storage conditions facilitates mycotoxin production which poses health risks, especially since Eastern Cape farmers lack quality control measures.

How can this research be applied to develop practical solutions for farmers?
Understanding the prevalence of fungi and mycotoxins in maize and other crops aids in devising targeted mitigation strategies. For instance, farmers could implement specific storage techniques or treatments to prevent the growth of fungi that produce these mycotoxins.
Additionally, exploring alternative crop options that are less prone to mycotoxin contamination could offer farmers diversified and safer cultivation choices.

It damages the liver and reduces milk production, growth rate, and fertility in livestock, and costing millions in some countries. While rare skin lesions occur, most animals show no signs but still suffer liver damage. This disease is spreading globally due to climate change.
What other health problems can mycotoxins cause in livestock?
Mycotoxins in animal feed can harm livestock – especially young ones – causing milk production drops, illness, and weak immune systems. These toxins can also build up in meat and milk, posing a health risk to people, especially babies. To protect both animals and us, we need to address mycotoxin contamination in food production.
How important is raising awareness to farmers on mycotoxins and the impact it has on their crops and livestock?
Educating South African farmers about mycotoxins is crucial for livestock and human health. Recent recalls of peanut butter due to aflatoxin contamination underscore the need for public awareness. Continuous monitoring ensures food safety.
Effective communication and collaboration empower farmers to prevent and manage mycotoxin contamination. This awareness fosters collaboration among farmers, scientists, stakeholders and policymakers, aiming to improve strategies for managing mycotoxin contamination on farms.
