Seibersdorf: Pistachios, once a delicacy reserved for royalty, are now at the forefront of a groundbreaking initiative to combat aflatoxin contamination using nuclear technology.

According to EMM, the Food and Agriculture Organization (FAO) and the International Atomic Energy Agency's (IAEA) Food Safety and Control Laboratory (FSCL) in Seibersdorf, Austria, has developed an innovative technique to detect aflatoxins in pistachios. Aflatoxins, produced by mould, are known carcinogens that have historically posed significant risks to food safety. These toxic compounds can result in severe health consequences, including liver failure and cancer, making their detection crucial.

The FSCL has introduced a cost-effective method involving sensors made from carbon-based ink printed on ceramic conductors. This technology can identify aflatoxin levels significantly lower than the permissible limits. The sensors, when used with a device called a Potentiostat, detect the presence of aflatoxins and relay the information to a mobile phone. This innovation provides a rapid, accessible solution for testing pistachios, particularly in regions with limited resources.

The global production of pistachios reached over one million tonnes in 2022, with Iran, the United States, and Turkey as leading producers. As demand increases, the risk of aflatoxin contamination becomes a pressing concern. The FSCL's portable testing method is a critical tool in addressing these concerns, offering a scalable solution that can be implemented in the field.

The IAEA's Joint FAO/IAEA Centre of Nuclear Techniques in Food and Agriculture is at the forefront of developing technologies that ensure food safety. Their Atoms4Food initiative aims to provide countries with the tools necessary to rapidly and effectively manage food safety emergencies. Efforts are underway to expand the application of this technology to detect other contaminants, including fumonisins in maize and toxic metals in fruit juices.

Christina Vlachou, Head of FSCL, emphasized the importance of these innovations, stating that they are essential for maintaining food safety and hygiene globally. As climate change exacerbates the spread of mycotoxins, the need for robust food safety interventions becomes even more critical.
