Ready-to-eat (RTE) street foods are usually prepared well in advance (4-8 hrs) before the sale. Owning to minimal cooking procedures, cross-contaminations, and abused holding temperature and time, there is a high probability for deteriorating microbiological quality in these foods. Thus, this study was aimed to assess the bacteriological quality of RTE foods sampled from night markets and street stalls based on the guidelines provided by the Public Health Laboratory Service. A total of fifty samples (category 2, 3 and 4) were evaluated for aerobic colony count, total coliform, and E. coli. The pathogenic strain E. coli O157: H7 were examined using the multiplex PCR technique. It was noticed that category 3 and 4 RTE street foods were largely unsatisfactory for the coliform (>104 CFU/ mL) and E. coli count (>100 CFU/mL). In opposite, category 2 RTE street foods were unsatisfactory for the aerobic colony count (>105 CFU/mL) and E. coli (>100 CFU/ mL). However, there was no E. coli O157: H7 or Shiga-toxin producing bacteria reported in this study. The statistical analysis showed that in overall, category 3 and 4 RTE street foods were significantly at worsening bacteriological quality compared to category 2. Strict legal enforcement and amending the existing rules are needed to improve the quality of RTE street foods sold in the night markets and street stalls.
