摘要

我们在内罗毕县进行了一项研究,以评估选定草药和香料中的黄曲霉毒素B1 (AFB1)水平,并确定产品使用情况和消费者对真菌和霉菌毒素污染的认识。使用R-studio软件1.4版对调查数据进行描述性统计分析。结果显示,消费者对草药和香料的偏好存在显著差异(P= 0.03671)。在一个月内消费的产品对顾客偏好有显著的预测作用(P= 0.0207)。65%的答复者不知道草药和香料中的真菌毒素,80%从未参加过真菌毒素培训。采用酶联免疫吸附法(ELISA)检测AFB1污染情况。在所有样品中均检测到黄曲霉毒素B1,香料中黄曲霉毒素B1的浓度范围为2.17 ~ 32.40ng/kg,草药中黄曲霉毒素B1的浓度范围为6.60 ~ 27.20 ng/kg。根据调查收集的消费数据,香料的AFB1日摄入量在0.83 ~ 11.78 ng/kg bw/d之间,草药的AFB1日摄入量在0.6 ~ 6.88 ng/kg bw/d之间。结果表明,接触真菌毒素的风险可能很高;因此,必须采取更严格的措施来防止真菌菌群污染草药和香料。

Prevalence of Aflatoxin B1 in marketed herbs and spices in Nairobi county Kenya: Consumer awareness, practices, and associated health risks
We conducted a study in Nairobi County to assess Aflatoxin B1 (AFB1) levels in selected herbs and spices and to ascertain product use and consumer  awareness of fungi and mycotoxin contamination. Descriptive statistical analysis of the survey data was performed using R-studio software version 1.4.  Results revealed significant differences in consumers' preference for herbs and spices (P= 0.03671). Products consumed in less than one month were  significant in predicting preference by customers (P= 0.0207). 65% of the respondents were unaware of mycotoxins in herbs and spices, and 80% had  never attended mycotoxin training. Enzyme-linked immunosorbent assay (ELISA) method was used to analyze the samples for AFB1 contamination.  Aflatoxin B1 was found in all of the samples and the concentration in spices ranged from 2.17ng/kg to 32.40ng/kg while in herbs the range was from  6.60ng/kg to 27.20 ng/kg.Considering the consumption data collected from our survey, the AFB1 daily intake for spices ranged between 0.83 and 11.78  ng/kg bw/day and in herbs it was between 0.6 and 6.88 ng/kg bw/day. The results indicate a high possible risk of exposure to mycotoxins; thus, more  stringent measures must be taken for the prevention of mycobiota contamination in herbs and spices.
