Aflatoxin contamination of Shiro and ground red pepper samples collected from government owned good stores, retail shops and open markets in. Addis Ababa was investigated. From sixty samples each of ground red pepper and Shiro, 8 (13.33%) and 5 (8.33%) were positive for aflatoxins, respectively. Only aflatoxin B1 was detected in both types of foodstuff. There was no significant difference between the proportion of aflatoxin contained in both ground red pepper and Shiro samples. Aflatoxin levels in Shiro and ground red pepper positive samples ranged from 100 to 500 ppb and 250 to 525 ppb, respectively. The mean levels of contamination by aflatoxin in ground red pepper was significantly higher (p < 0.05) than that of Shiro. Though statistically not significant, the number of positive samples were more in samples from open markets when compared to samples from government owned food stores and retail shops. Conclusions are drawn that ground red pepper and shiro traded in Addis Ababa can be considered as high risk commodities for which routine survey of aflatoxins may be necessary.
对从亚的斯亚贝巴政府所有的优质商店、零售店和露天市场采集的希罗（Shiro）和红辣椒粉样本的黄曲霉毒素污染情况进行了调查。在红辣椒粉和希罗的各60个样本中，黄曲霉毒素呈阳性的分别有8个（13.33%）和5个（8.33%）。在这两种食品中均仅检测到黄曲霉毒素B1。红辣椒粉和希罗样本中所含黄曲霉毒素的比例之间没有显著差异。希罗和红辣椒粉阳性样本中的黄曲霉毒素水平分别为100至500 ppb和250至525 ppb。红辣椒粉中黄曲霉毒素的平均污染水平显著高于希罗（p < 0.05）。与政府所有食品商店和零售店的样本相比，露天市场样本中的阳性样本数量虽无统计学意义上的显著差异，但更多。得出的结论是，在亚的斯亚贝巴交易的红辣椒粉和希罗可被视为高风险商品，可能需要对其进行黄曲霉毒素的常规检测。
