Bacteriological quality of beef-contact surfaces, air microflora and wastewaters from major abattoirs located in Benin City, Southern Nigeria
Abstract
The bacteriological quality of beef produced from most abattoir located in southern Nigeria has always been questionable. This work therefore investigated the bacteriological quality of abattoir facilities from both government and private owned abattoirs located in southern Nigeria. The results of our findings revealed that the total heterotrophic counts and total coliform counts exceeded the recommended standard for sanitary practices. Total heterotrophic counts from air flora ranged from 14.50 x 106 to 42.50 x 106 cfu. Beef-contact surface ranged from 26.50 x 106 to 592.50 x 106 cfu while total colony counts obtained from wastewaters from both government and private abattoirs ranged from 140.00 x 106 to 1206.75 x 106cfu/ml. The total coliform counts also ranged from 14.25 x 103 to 33.75 x 103 for air flora and 76.00 x 103 to 195.00 x 103cfu/ml for wastewaters. Eight bacterial isolates were consistently isolated during this study, and they included; Escherichia coli, Staphylococcus aureus, Staphylococcus sp., Citrobacter sp., Alcaligenes paradoxus, Klebsiella sp. and Enterococcus faecalis with varying percentage of frequency across the sampling points. The presence ofindicator organisms as well as possible pathogens in this study is of special concern and stakeholders should be encouraged to review the processes involved in the establishment as well as operation of abattoir in southern Nigeria.
