Microbiological Quality of Salads Served along with Street Foods of Hyderabad, India

[摘要] A study has been done to analyse the microbiological quality of salads served along with street foods of Hyderabad. A total of 163 salad samples, 53 of carrot and 110 of onion samples, were collected from four different zones of Hyderabad. About 74% and 56% hadStaphylococcus aureusin carrots and onions, respectively. Fifty-eight percent of carrots and forty-five percent of onions samples containedSalmonella, 68% of carrots and 24% of onions hadYersinia. HACCP study was carried out with 6 street food vendors to identify the source ofSalmonellacontamination in salads. Food handlers were found to be responsible forSalmonellacontamination in salads. The present study revealed the potential hazards of street vended salad vegetables, considering the handling practice usually carried out by vendors. Ninety-eight percent of the vendors did not wash the vegetables before processing and serving while about 56.6% of the vendors did not peel the vegetables. Majority of street vendors’ nails were uncut. A significant difference (P<0.01) was observed inYersiniaspp. andSalmonellaspp. in wet-dirty chopping board when compared to clean-dry chopping board. A significant difference (P<0.05) ofStaphylococcusspp. was observed when the status of cleaning cloth was neat/untidy.
