EVALUATION OF BACTERIA ISOLATED IN BAKERY ENVIRONMNETS IN UMUAHIA, ABIA STATE

ABSTRACT

A toatal number of six (6) bacteria genera wer isolated from five (5) bakery environments in Umuahia, Abia State. The isolated bacteria include, Staphylococcus aureus, Escherichia coli, Bacillus sp. Klebsiella Pneumonia. Pseudomonas Aeruginosa and Salmonella sp. The highest bacteria count of 7.0×104 cfu/cm3 was recorded by sample from Santana bread bakery (SBB) while  the least count of 5.4 ×104 cfu/cm3  was recorde by sample from High class bread (HCB) and favourite bakery (FB) respectively. Frequency distribution of the isolates showed that Staphlococcus  aureus were (13.0%). Pseudomonas aeruginosawere (16.8%), Escherichia coli were (13.5%). Bacillus spp were (33.3%). Klebsiella Pneumonia were (11.1%), and Salmonella spp were (12.3%). The antibiotics sensitivity and resistance test showed that Escherichia coli recorded the highest sensitivity of 20mm on ciprofloxacin. Klebsiellaspp recorded the least sensitivity of 4.0mm on gentamycin.
