Abstract
In India, the street food trade is a growing sector with its expansion linked with urbanisation and the need of urban populations for both employment and food. However, the microbiological status of popularly consumed raw street foods, general hygienic and vending practices are not known. We visited 75 vendors (50 having fixed stalls and 25 with mobile stalls) operating in three major locations: mandi (open market place), bus terminus and railway station in New Delhi and Patiala City. A total of 150 samples each of coriander sauce, of ready-to-eat salads and coconut slices collected were analysed for Staphylococcus aureus and Shigella spp. Enterotoxigenic Staphylococcus aureus were detected in 91 (60%) samples of coriander sauce, 87 (58%) samples of coconut slices and 129 (86%) samples of ready-to-eat salads. Twenty-three (15%) samples of coconut slices contained Shigella (18 Sh. dysenteraie type 1 and 5 Sh. flexneri 2a), 13 (8%) samples of ready-to-eat salads and 10 (6%) samples of coriander sauce contained Sh. flexneri 2a. Street vendors lacked access to potable water, toilet facilities and operated under poor hygiene conditions. The results of our study suggest that street vended coconut slices, coriander sauce and ready-to-eat salads could be important potential vehicles for food-borne diseases.
