This study aimed to assess the microbiological quality of tiger nut (Cyperus esculentus L.) products sold in Ouagadougou and Bobo Dioulasso. The microbial load of tubers and tiger nut milk was determined using ISO 4833-1 (2003) standard (total mesophilic aerobic flora), NF ISO 7954 (1998) standard (yeasts and molds), and ISO 4832 (2006) standard (total coliforms, thermotolerant coliforms). The results showed that tiger nut tubers had an average microbial load between 4.86 ± 7.03 × 10<sup>6</sup> UFC/g and 1.82 ± 2.30 × 10<sup>7</sup> UFC/g for total mesophilic aerobic flora, from 4.34 ± 10.6 × 10<sup>5</sup> UFC/g to 3.52 ± 4.54 × 10<sup>6</sup> UFC/g for yeasts and molds, from 2.23 ± 2.25 × 10<sup>5</sup> UFC/g to 1.41 ± 2.16 × 10<sup>5</sup> UFC/g for total coliforms and from 1.83 ± 2.03 × 10<sup>5</sup> UFC/g to 7.0 ± 10.8 × 10<sup>4</sup> CFU/g for thermotolerant coliforms. For tiger nut milk samples, the average microbial load varied from 3.48 ± 2.98 × 10<sup>6</sup> CFU/g to 2.80 ± 5.69 × 107 CFU/g for total mesophilic aerobic flora, from 5.00 ± 7.21 × 10<sup>4</sup> CFU/g to 1.88 ± 3.31 × 10<sup>5</sup> CFU/g for yeasts and molds, from 4.58 ± 10.4 × 10<sup>4</sup> CFU/g to 6.31 ± 9.17 × 10<sup>5</sup> CFU/g for total coliforms and 7.00 ± 7.00 × 10<sup>3</sup> CFU/g to 2.87 ± 5.86 × 10<sup>5</sup> CFU/g for thermotolerant coliforms. This study revealed that the tubers and tiger nut milk sold in Ouagadougou and Bobo Dioulasso had a high microbial load which could lead to the degradation of these products and food poisoning for consumers. 展开更多
