Garri is consumed by several millions of people in the West African sub-region and in Nigeria in particular, regardless of ethnicity and socio-economic class. However, production and handling methods have not been standardized, resulting in a product with varying quality and safety indices hence varying public health concern.
To investigate the microbial contamination level, presence, prevalence and distribution of aflatoxins B₁, B₂, G₁ and G₂ in market garri with the aim of developing useful indices for safe handling and acceptable public health standards.
A total of 300 samples comprising of 30 samples each from various market in both urban and rural settings were randomly collected using sterile polyethylene bags. These were analysed for microbiological quality and aflatoxins content using standard procedures.
Eight bacteria genera (Bacillus, Staphylococcus, Streptococcus, Pseudomonas, Clostridium, Salmonella Klebsiella and Coliforms groups) genera and six fungi genera (Aspergillus, Penicillium, Rhizopus, Botrytls, Fusarium and Cladosporium) were detected and isolated. Aflatoxins B₁, B₂, G₁ and G₂ were detected in varying concentrations amongst the samples analysed within and amongst the states investigated with an average occurrence rate of 17.5%
Market garri was found to contain high bioload with vast array of micro-organisms and aflatoxins in all the states investigated. Results are useful in developing and establishing public health standards for the production and safe handling of garri.
在西非次区域，尤其是在尼日利亚，数百万人食用加里（一种食物），无论其种族和社会经济阶层如何。然而，其生产和处理方法尚未标准化，导致产品的质量和安全指标各不相同，因此引起了不同程度的公共卫生关注。
调查市售加里中黄曲霉毒素B₁、B₂、G₁和G₂的微生物污染水平、存在情况、流行率和分布，旨在制定安全处理的有用指标和可接受的公共卫生标准。
使用无菌聚乙烯袋从城乡各地的不同市场随机收集总共300个样本，每个市场30个样本。采用标准程序对这些样本进行微生物质量和黄曲霉毒素含量分析。
检测并分离出八个细菌属（芽孢杆菌属、葡萄球菌属、链球菌属、假单胞菌属、梭菌属、沙门氏菌属、克雷伯氏菌属和大肠菌群）和六个真菌属（曲霉属、青霉属、根霉属、葡萄孢属、镰刀菌属和枝孢属）。在所调查的州内和州际分析的样本中，检测到不同浓度的黄曲霉毒素B₁、B₂、G₁和G₂，平均检出率为17.5%。
在所调查的所有州，市售加里被发现含有大量微生物和黄曲霉毒素，生物负荷很高。研究结果有助于制定和建立加里生产及安全处理的公共卫生标准。
