ABSTRACT:   Bacterial pathogen contamination of 81 food samples from Pazundaung, Mingalar Taungnyunt and Pabedan Townships was carried out from June 2002 to May 2004. These samples were 26, 21, 19 and 15 of noodles, bread, biscuits and cookies respectively. The total bacterial count, total coliform and faecal coliform count were tested in all those food samples using conventional methods. Plasmid isolation was done on Escherichia coli isolates. In this study, the Colony Forming Units (CFU) of bacteria counted were >7.5 x 105 organisms/gram in 27 samples (33.33%); 1.5 x 104 to 7.5 x 105 CFU/gram in 26 samples (32.09%); and <2 CFU/gram in 28 samples (34.56%). Coliforms (100%) and faecal coliforms (61.53%) were identified from noodles. From bread, coliforms (71.42%) and faecal coliforms (28.57%) were identified. From biscuits, coliforms (71.42%) and faecal coliforms (21.05%) were identified. Also, coliforms (46.66%) and faecal coliforms (20.0%) were identified in cookies. From all foods tested, coliforms were isolated in 72.83% and faecal coliforms in 35.80%. Staphylococcus species was isolated from 46.15% of noodles and 37.50% of bread, however, none from biscuits and cookies. Bacillus species was isolated from 92%, 76.19%, 21.05%, and 33.33% of noodles, bread, biscuits and cookies respectively.Escherichia coli was isolated from 100%, 71.42%, 21.05% and 53.33% of noodles, bread, biscuits and cookies respectively. Nine isolates of E. coli were serogrouped as O55K59 (5 isolates) and one each of O8K25, O26K50, O114K90 and O142K+. They were isolated from 6, 2 and 1 samples of noodles, bread and cookies respectively. However, Salmonella, Shigella and Vibrios (O1 and O139) were not isolated in this study. The plasmid size of E. coli isolates in this study was 23 kilo base pairs.
