Abstract

Multi-mycotoxin analysis of 22 mycotoxins in 202 durum wheat samples collected in Algeria from 2019 to 2021 was performed by UHPLCMS/MS. Enniatins were present in 2 out of 45 wheat samples in the 2019 harvest, whereas in the harvest of 2020 37.6% of wheat samples were contaminated by ochratoxin A and/or beauvericin, deoxynivalenol (1076 µg/kg), fumonisin B1, enniatins, and zearalenone (most prevalent in 2020 and 2021 harvest). Mycotoxin contamination increased from 37.6% in 2020 to 55.2% in 2021 harvests. The most frequently observed mycotoxin co-occurrence was the combination of enniatin A1, enniatin B, and enniatin B1 (0.5-126 µg/kg) and DON (1307 µg/kg). AFB1 (0.4-2.6 µg/kg) was found in only one sample collected from the continental region. These results pointed to the necessity of frequent and regular wheat quality controls in order to better evaluate the risk regarding the Algerian population.

从阿尔及利亚两个气候区收集的收获前、收获后和储存小麦谷物中的真菌毒素。

采用UHPLCMS/MS对2019 - 2021年在阿尔及利亚采集的202份硬粒小麦样品中的22种真菌毒素进行了多真菌毒素分析。在2019年收获的45个小麦样品中，有2个样品中含有Enniatins，而在2020年收获的小麦样品中，37.6%的小麦样品被赭曲霉毒素A和/或beauvericin、脱氧雪腐菌醇（1076 μ g/kg）、伏马菌素B1、Enniatins和玉米赤霉烯酮污染（在2020年和2021年收获时最为普遍）。霉菌毒素污染从2020年的37.6%上升到2021年的55.2%。最常见的真菌毒素共现是enniatin A1、enniatin B和enniatin B1（0.5 ~ 126µg/kg）和DON（1307µg/kg）的组合。AFB1（0.4-2.6µg/kg）仅在大陆地区的一个样品中被发现。这些结果表明，必须经常和定期控制小麦质量，以便更好地评估阿尔及利亚人口面临的风险。

期刊介绍： Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling. Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment. The scope is initially restricted to: Additives - food colours, artificial sweeteners, and preservatives; Residues – veterinary drug and pesticide residues; Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging. Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet. Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
