| dc.description.abstract | This study was carried out to investigate the microbiological quality of different street
food (Amra, Fusca, Chanachur and Guava) sold by various street vendor at Dinajpur,
Bangladesh. A total of 20 samples were collected randomly from street vendors in
Dinajpur and tested for the presence of bacteria following conventional microbiological
processes. Among 20 Amra, Fusca, Chanachur and Guava food samples, all (100%) had
bacterial contamination. The total viable count (TVC) in diferrent street food samples
was ranged from 8.0 × 105 CFU/g to 6.7x107 CFU/g. Among the 20 samples Escherichia
coli 7(35%), Staphylococcus spp 6(30%), Klebsiella spp 5(25%), Salmonella spp 1(5%)
and Shigella spp 1 (5%) were isolated and identified from the samples. In 20 street food
samples Escherichia coli were found highest 3(50%) Amra samples and 2(40%) Guava
samples, then another organisms Staphylococcus spp was found highest 2(50%)
Chanachur and 2(40%) Fusca samples and then Klebsiella spp was found highest 2(40%)
Fusca samples. Antibiotic sensitivity test showed that Shigella spp, Staphylococcus spp,
Klebsiella spp, Salmonella spp and Escherichia coli were sensitive to Ciprofloxacin.
Staphylococcus spp, Klebsiella spp, Escherichia coli were sensitive to Gentamycin and
found Salmonella spp resistance to Gentamycin. Klebsiella spp and Staphylococcus spp
were sensitive to Neomycin and found Shigella spp were resistance to Neomycin.
Klebsiella spp and Shigella spp were intermediate sensitive to Kenamycin. All isolates
found resistant to Cefixime, Cefalexin, Erythromycin, Fusidic acid, Cefuroxime and
Aztreonam. This study indicated that the different street foods showed wide range of
TVC which exceed acceptance level. According to the microbiological standard of foods
in Bangladesh, aerobic plate counts ranges from 10 to 102 CFU/ g can be said to be safe,
102
to < 104 CFU/g acceptable, 104
to <105 CFU/g not acceptable and =105 CFU/g can
be said to be extremely hazardous for public health. All of the sample harbor multidrug
resistant food borne bacteria which might cause public health hazards if these antibiotic
resistance transfer to human. Hence, it is recommended that a more close supervision of
such food type should be carried out by relevant authorities to avoid any future pathogen
outbreaks. | en_US |
