Abstract  

Objectives: Information on the distribution and presence of microbiology and chemical hazard of commercial attieke (a fermented cassava product) produced in the south of Cote d’Ivoire were evaluated. 

Materials and Methods: Microbiological analyses and chemical were carried out, which included the total viable bacteria, Staphylococcus aureus, Salmonella and Bacillus spores, heavy metal (pb, Cd, Mn, Fe, Cu, and Cr). 

Results and Conclusions: The results revealed that the viable bacteria counts ranged from in all of samples. Staphylococcus aureus counts in the samples were comprised between (1.8 ± 0.4)102 (Jacqueville localitie) and (4.3 ± 1.8)103 (Abidjan localitie). While that of Bacillus cereus was ranged from (1.1 ± 0.9)102 (Adzopé localitie) and (5.1 ± 3.2)102 (Abidjan localitie). Salmonella spp. was not found. The levels of Pb in all samples were between 2.2 ± 0.1 mg/kg (Grand-lahou localitie) and 4.5 mg/kg ± 0.15 (Abidjan localitie) while the Cd levels of the samples varied between 0.02 ± 0.1 mg/kg (Adzopé localitie) and 0.07± 0.1  mg/kg (Divo localitie). The levels of Cr in the samples were comprised between 0.1 ± 0.03 mg/kg (Adzopé localitie) and 0.95 ± 0.1 mg/kg (Abidjan localitie) while Fe (7.3 ± 1.5 mg/kg) and Cu (1.7 ± 0.2 mg/kg) levels were the highest, respectively in Sikensi and Grand-Lahou localities. Samples from Divo localitie contained high amounts of Mn (1.6 ± 0.1 mg/kg). 

The occurrence of some microbiological and chemical hazard that commercial attieke collected in Cote d’Ivoire may act as a reservoir of pathogenic micro-organisms and heavy metal for human.

科特迪瓦南部生产的商品木薯(发酵木薯制品)的微生物和化学危害

【目标】研究并评估科特迪瓦南部生产的商品木薯中微生物分布和化学危害。
【材料和方法】进行微生物和化学分析,包括活菌总数、金黄色葡萄球菌、沙门氏菌和芽孢杆菌、重金属(铅、镉、锰、铁、铜和铬)。
【结论】结果表明,所有样品中的活菌数均为:金黄色葡萄球菌计数在(1.8±0.4)102(雅克维尔地区)和(4.3±1.8)103(阿比让地区)之间。蜡样芽胞杆菌在(1.1±0.9)102(adzopé)和(5.1±3.2)102(阿比让)之间。未发现沙门氏菌。所有样品的铅含量在2.2±0.1 mg/kg(大拉胡地区)和4.5 mg/kg±0.15(阿比让地区)之间,而镉含量在0.02±0.1 mg/kg(阿德佐佩地区)和0.07±0.1 mg/kg(迪沃地区)之间。样品中铬含量在0.1±0.03mg/kg(阿比让地区)和0.95±0.1mg/kg(阿比让地区)之间,而铁(7.3±1.5mg/kg)和铜(1.7±0.2mg/kg)含量最高,分别位于锡肯和大拉胡地区。Divo地区的样品含有大量的锰(1.6±0.1 mg/kg)。

在科特迪瓦收集木薯产品可能存在一些微生物和化学危害,成为人类致病微生物和重金属的储藏库。
