The main goal of the present research was to explore the seasonal variation of deoxynivalenol (DON) in wheat, corn, and their products, collected during 2018–2019. Samples of 449 of wheat and products and 270 samples of corn and their products were examined using reverse-phase liquid chromatography with a UV detector. The findings of the present work showed that 104 (44.8%) samples of wheat and products from the summer season, and 91 (41.9%) samples from winter season were contaminated with DON (concentration limit of detections (LOD) to 2145 µg/kg and LOD to 2050 µg/kg), from summer and winter seasons, respectively. In corn and products, 87 (61.2%) samples from summer and 57 (44.5%) samples from winter season were polluted with DON with levels ranging from LOD to 2967 µg/kg and LOD to 2490 µg/kg, from the summer and winter season, respectively. The highest dietary intake of DON was determined in wheat flour 8.84 µg/kg body weight/day from the summer season, and 7.21 µg/kg body weight/day from the winter season. The findings of the work argued the need to implement stringent guidelines and create awareness among farmers, stakeholders, and traders of the harmful effect of DON. It is mostly observed that cereal crops are transported and stockpiled in jute bags, which may absorb moisture from the environment and produce favorable conditions for fungal growth. Therefore, these crops must store in polyethylene bags during transportation and storage, and moisture should be controlled. It is highly desirable to use those varieties that are more resistant to fungi attack. Humidity and moisture levels need to be controlled during storage and transportation.

小麦，玉米及其制品中脱氧雪腐烯醇的评估以及膳食摄入量的估算。

本研究的主要目的是探讨在2018-2019年期间收集的小麦，玉米及其产品中的脱氧雪腐烯醇（DON）的季节变化。使用带紫外检测器的反相液相色谱法检查了449份小麦和产品的样品以及270份玉米及其产品的样品。当前工作的发现表明，夏季的104份（44.8％）小麦和产品样品和冬季的91份（41.9％）样品被DON（检出限（LOD））污染至2145 µg / kg。和LOD至2050 µg / kg），分别从夏季和冬季开始。在玉米和产品中，从夏季和冬季开始，DON污染了夏季的87个样品（61.2％）和冬季的57个样品（44.5％），其水平从LOD到2967 µg / kg，从LOD到2490 µg / kg。季节。从夏季开始，小麦粉的日粮摄入量最高，为8.84 µg / kg体重/天，从冬季开始，小麦粉中的DON摄入量最高，为7.21 µg / kg体重/天。这项工作的结果表明，有必要执行严格的指导方针，并在农民，利益相关者和贸易商之间建立对呕吐毒素有害影响的认识。普遍观察到谷物作物是在黄麻袋中运输和储存的，可能会吸收环境中的水分并为真菌的生长创造有利条件。因此，这些农作物在运输和储存过程中必须储存在聚乙烯袋中，并应控制湿度。非常希望使用对真菌侵袭更具抗性的那些品种。在储存和运输过程中需要控制湿度和水分含量。
