This study aimed to estimate the prevalence and concentration of total aflatoxin (TAF) ochratoxin A (OTA), zearalenone (ZEN) and deoxynivalenol (DON) in bread, cornflakes, breakfast cereals and pasta-based products through meta-analysis. The required databases including (PubMed and Scopus databases) were investigated to collect data on the concentration and prevalence of mentioned mycotoxins in cereal-based products. Among 2461 explored articles in identification step, 38 articles with 9627 samples were included in the conducted meta-analysis. The prevalence and concentration of studied mycotoxins varied with the cereal-based food studied. In this context, the overall rank order of mycotoxins prevalence in the cereal foods was OTA > DON > ZEN > TAF > 15-ADON > 3-ADON. Also, the overall rank order of mycotoxins based on concentration in the cereal foods investigated was DON > ZEN > 15-ADON > OTA > 3-ADON > TAF. The findings of this meta-analysis may be useful for the building of risk assessment models aiming to derive data for the development of specific actions to reduce the exposure to OTA, ZEN, TAF, and DON through the consumption of the cereal-based products.

这项研究旨在通过荟萃分析来评估面包，玉米片，早餐谷物和面食类产品中总黄曲霉毒素（TAF）A曲霉毒素A（OTA），玉米赤霉烯酮（ZEN）和脱氧雪茄烯醇（DON）的存在和浓度。调查了所需的数据库，包括（PubMed和Scopus数据库），以收集有关谷物类产品中上述霉菌毒素的浓度和患病率的数据。在鉴定步骤中探索的2461篇文章中，进行的荟萃分析包括38篇文章和9627个样本。所研究的真菌毒素的发生率和浓度随所研究的谷类食品而异。在这种情况下，谷物食品中霉菌毒素的总体流行顺序为OTA> DON> ZEN> TAF> 15-ADON> 3-ADON。还，根据所调查谷物食品中的浓度，真菌毒素的总体排名为DON> ZEN> 15-ADON> OTA> 3-ADON> TAF。这项荟萃分析的结果对于建立风险评估模型可能有用，该模型旨在获取数据以制定具体行动，以减少通过食用谷物类产品而暴露于OTA，ZEN，TAF和DON的风险。
