No. Intervention strategies Elemental description Ref. 1 Improved agricultural practices Proper agricultural practices like effective drying, storage, and handling of crops can reduce Aflatoxin contamination pre- and post-harvest. [52] 2 Adoption of Aflatoxin-resistant varieties Research should focus on breeding crops resistant to Aflatoxin-producing fungi to reduce contamination. [53] 3 Enhanced food safety regulations Enhancing food safety rules and enforcement ensures adherence to Aflatoxin limits, protecting public health and boosting trade. [54] 4 Education and awareness campaigns Raising awareness about Aflatoxin risks and prevention among all stakeholders is crucial for adopting best practices. [55] 5 Investment in infrastructure Investing in detection and monitoring infrastructure and technology can reduce Aflatoxin contamination risks in the food supply chain. [56] Table 2.
