In this study, 81 samples of two cowpea varieties (brown: 54; white: 27) collected from various markets in southwestern Nigeria were examined for fungal and mycotoxin contamination. Moulds belonging to Aspergillus, Fusarium, and Penicillium were recovered from 99% of the samples. In both cowpea varieties, Aspergillus (52-53%) dominated Fusarium (29-30%) and Penicillium (17-20%). The interactive effect of cowpea variety and sampled location was significant (p = .013) on the occurrence of Fusarium species. Aflatoxins were detected in one brown and two white cowpea samples at concentrations reaching 209 and 84 µg/kg, respectively. Additionally, beauvericin was found in two samples of each cowpea variety, albeit at low concentrations. Cowpea presents as an alternative vegetable protein source to groundnuts in household nutrition with respect to mycotoxin contamination. Simple techniques to prevent mycotoxins in dry cowpeas are discussed.

尼日利亚市场上cow豆（Vigna unguiculata L）中的真菌和霉菌毒素。

在这项研究中，从尼日利亚西南部的各个市场收集的两种81豆品种（棕色：54；白色：27）的81个样品进行了真菌和霉菌毒素污染检测。从99％的样品中回收了属于曲霉，镰刀菌和青霉菌的霉菌。在两个cow豆品种中，曲霉菌（52-53％）占镰刀菌（29-30％）和青霉菌（17-20％）。Fu豆品种和采样位置的交互作用对镰刀菌种的发生具有显着影响（p = .013）。在一个棕色和两个白色cow豆样品中检出的黄曲霉毒素浓度分别达到209和84 µg / kg。此外，在每种cow豆品种的两个样品中都发现了紫红霉素，尽管浓度很低。就霉菌毒素污染而言，Cow豆作为家庭营养中花生的替代植物蛋白来源。讨论了防止干cow豆中霉菌毒素的简单技术。
