Aflatoxins are mainly produced by certain strains of , which are found in diverse agricultural crops. In many lower-income countries, aflatoxins pose serious public health issues since the occurrence of these toxins can be considerably common and even extreme. Aflatoxins can negatively affect health of livestock and poultry due to contaminated feeds. Additionally, they significantly limit the development of international trade as a result of strict regulation in high-value markets. Due to their high stability, aflatoxins are not only a problem during cropping, but also during storage, transport, processing, and handling steps. Consequently, innovative evidence-based technologies are urgently required to minimize aflatoxin exposure. Thus far, biological control has been developed as the most innovative potential technology of controlling aflatoxin contamination in crops, which uses competitive exclusion of toxigenic strains by non-toxigenic ones. This technology is commercially applied in groundnuts maize, cottonseed, and pistachios during pre-harvest stages. Some other effective technologies such as irradiation, ozone fumigation, chemical and biological control agents, and improved packaging materials can also minimize post-harvest aflatoxins contamination in agricultural products. However, integrated adoption of these pre- and post-harvest technologies is still required for sustainable solutions to reduce aflatoxins contamination, which enhances food security, alleviates malnutrition, and strengthens economic sustainability.
黄曲霉毒素主要由某些 菌株产生,这些菌株存在于多种农作物中。在许多低收入国家,黄曲霉毒素引发了严重的公共卫生问题,因为这些毒素的出现相当普遍,甚至很严重。受污染的饲料会使黄曲霉毒素对家畜和家禽的健康产生负面影响。此外,由于高价值市场的严格监管,它们还严重限制了国际贸易的发展。由于黄曲霉毒素具有很高的稳定性,其问题不仅出现在种植过程中,在储存、运输、加工和处理环节也会出现。因此,迫切需要创新的循证技术来尽量减少黄曲霉毒素的暴露。到目前为止,生物防治已被开发为控制作物中黄曲霉毒素污染最具创新性的潜在技术,该技术利用非产毒菌株竞争性排斥产毒菌株。这项技术已在收获前阶段商业化应用于花生、玉米、棉籽和开心果。其他一些有效的技术,如辐照、臭氧熏蒸、化学和生物防治剂以及改良的包装材料,也可以减少农产品收获后黄曲霉毒素的污染。然而,要实现减少黄曲霉毒素污染的可持续解决方案,仍需要综合采用这些收获前和收获后的技术,这将增强粮食安全、缓解营养不良并加强经济可持续性。
