Identification and antibiogram study of bacteria isolated from different street food

Abstract

Food borne diseases are an increasingly recognized problem involving a wide spectrum of illnesses caused by bacterial contamination of food.Microorganism poses potential human health problems and is mainly transmitted through consumption of contaminated foods .Bangladesh is one of the densely populated country where majority of the people consume cheap foods prepared in unlicensed food selling points. The objective of the present study was 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 and tested for the presence of bacteria following standard microbiological method used for isolation, enumaration and identification of bacreria. Among the samples all 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 samples Escherichia coli 7(35%), Staphylococcus spp. 6(30%), Klebsiella spp. 5(25%), Salmonella spp. 1(5%) and Shigella spp. 1 (5%) were isolated. 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 and Salmonella spp. were resistance to Gentamycin. All isolates found resistant to Cefixime, Cefalexin, Erythromycin, Fusidic acid, Cefuroxime and Aztreonam. All of the sample harbor multidrug resistant food borne bacteria which might cause public health hazards if these antibiotic resistance transfer to human.Asian J. Med. Biol. Res.

Occurrence and antimicrobial susceptibility of Salmonella isolates from grilled chicken meat sold at retail outlets in Erbil City, Kurdistan region, Iraq

“…These results are consistent with an Egyptian study in Luxor city which found that the isolation rate of Salmonella in ready-to-eat meat (RTE) samples was 6.67% (Younis et al ., 2019). However, a slightly lower rates were reported in Bangladesh (5%) and in Egypt (4.4%) where Salmonella prevalence in street food was 5 % (Abd- El–Malek, 2017; Khalif et al ., 2018). In contrast, higher rates where reported from Korea (22.4%), Australia (38.8%), and China (54%) (Kim et al ., 2012; Fearnley et al ., 2011; Yang et al ., 2010).…”

Antibiotic resistance patterns of Staphylococcus aureus and Enterobacteriaceae isolated from street foods in selected towns of Ethiopia

“…Street food is defined as the type of food and beverages that are prepared or sold by street vendors in public areas for human consumption, with or without the need for additional processing and preparation [ 1 – 3 ]. It is an important business that helps developing nations meet the food needs of the poor [ 4 ] and promote socioeconomic development by providing employment for many unemployed people [ 2 , 5 , 6 ]. Besides, they attract tourists in some Asian countries [ 5 , 7 ].…”

“…Lack of training on proper food handling and processing, poor personal hygiene of vendors, and unsanitary surroundings could all be contributing factors to the observed safety issues [ 2 , 4 ], which often lead to the rise of various food-borne diseases that can be life-threatening [ 3 ]. The issue is most pronounced in countries with insufficient food safety laws, weak regulatory systems, limited financial resources for safer equipment, and food safety training [ 12 ].…”

“…Studies from Africa and other continents revealed that some microorganisms of public health concern detected in street foods include Bacillus cereus, Escherichia coli, Clostridium perfringens, Proteus spp., Staphylococcus spp., Salmonella spp., and others [ 2 , 4 , 9 , 12 , 17 – 23 ]. Infections caused by Salmonella and Shigella are among the major public health problems in tropical and subtropical regions of the world [ 17 ].…”

Bacterial risk evaluation of widely consumed fast foods by the younger population in Bangladesh and its potential health effects

“…Street food refers to food and drinks that are prepared and sold by fast vendors or retailers, typically on the spot or in the same public place, for local consumption or later consumption without further preparation [1]. Vendors or manufacturers usually prepare street food in mobile food carts or food trucks, and it is intended to be consumed by customers.…”
