This study, conducted in the city of Butembo from January 6, 2019 to August 24, 2021, consisted in assessing the microbiological quality of two foodstuffs delivered for human consumption: cooked yellow yams (Dioscorea cayensis) and ripe bananas (Musa accuminata balbisiana) as well as to determine the frequencies of microbial pollution in these two foodstuffs in order to inquire about the danger to consumers who are exposed to it. The microbiological analysis of 80 samples of yellow yams taken from the four markets of the city of Butembo revealed an overall pollution of 95%, with 37.5% of simple microbial pollution dominated by Streptococcus spp (17.5%), followed by Enterobacter sakazaki and Staphylococcus other than aureus which each have 7.5%, finally Enterabacter agglomerans1 and Staphylococcus aureus which each have 2.5%. The statistical analysis of these results showed that the frequencies of simple and mixed microbial pollution are significantly different (P<0.05) in the four markets of the city of Butembo (X2c=respectively 14.38 and 12.14; dll =3). In addition, the microbiological analysis of 80 samples of ripe bananas taken from the four markets of the town of Butembo revealed an overall contamination rate of 65% dominated by Hafnia sp (25%), followed by Pseudomonas fluorescens (15%), Aeromonas spp and Klebsiella pneumoniae which each have (10%), finally Alcaligene dispar (5%). These frequencies of bacterial pollution in the ripe bananas examined are significantly different (P<9.89) in the four markets of the city of Butembo (X2c=9.8; ddl=3).

Abstract: (french)
Cette étude, menée en ville de Butembo du 06 Janvier 2019 au 24 Août 2021, consistait à apprécier la qualité microbiologique de deux denrées alimentaires livrées à la consommation humaine: les ignames jaunes cuites (Dioscorea cayensis) et la banane mure (Musa accuminata balbisiana) ainsi que de déterminer les fréquences de pollutions microbiennes dans ces deux denrées afin de s’enquérir du danger que courent les consommateurs qui en sont exposés. L’analyse microbiologique de 80 échantillons d’ignames jaunes prélevés dans les quatre marchés de la ville de Butembo ont révélé une pollution globale de 95%, avec 37,5% de pollution microbienne simple dominée par Streptococcus spp (17,5%), suivi de Enterobacter sakazaki et Staphylococcus autre que aureus qui ont chacun 7,5%, enfin Enterabacter agglomerans1 et Staphylococcus aureus qui ont chacun 2,5%. L’analyse statistique de ces résultats a montré que les fréquences de pollution microbiennes simples et mixtes sont significativement différentes (P<0,05) dans les quatre marchés de la ville de Butembo (X2c=respectivement 14,38 et 12,14; dll=3). Par ailleurs, l’analyse microbiologique de 80 échantillons de la banane mure prélevés dans les quatre marchés de la ville de Butembo ont révélé un taux de contamination globale de 65% dominé par Hafnia sp (25%), suivi de Pseudomonas fluorescens (15%), Aeromonas spp et Klebsiella pneumoniae qui ont chacun (10%), enfin Alcaligene dispar (5%). Ces fréquences de pollutions bactériennes dans les bananes mures examinées sont significativement différentes (P<9,89) dans les quatre marchés de la ville de Butembo (X2c=9,8; ddl=3).
