Résumé

Present study was conducted to assess microbiological quality of industrially produced and street vended ice-cream. The ice-cream samples were collected from four different brands (Igloo, Polar, Kwality & Bellisimo) and street vendors in different areas of Dhaka city. The Aerobic Plate Count was found range from 20 x 102 to 200 × 102 cfu /ml in industrially produced ice-cream samples and 41 x 102 to 430 x 103 cfu/ml in street vended ice-cream samples. 72.5 % of industrially produced ice-cream and 100% of the street vended ice-cream were contaminated with total Coliform whereas 20% industrially produced and 90.90% street vended ice cream exceeded the limit of BSTI standard for Coliform. Among the industrially produced ice-cream highest extent of microbial contamination was found in Kwality ice-cream. Two samples (5%) from industrially produced ice-cream and 11 samples (34%) from street vendors were confirmed to have contamination with E. coli. Salmonella spp was not found in industrially produced ice-cream and 5 samples (15.15 %) from street vendors were contaminated with Salmonella spp. 35 % of industrially produced and 85 % of street vended ice-cream samples were contaminated with Staphylococcus aureus. The present study demonstrates that industrially produced ice-cream samples are safer than street vendors. Street vended ice-cream samples are not complying with microbiological specifications of BSTI and indicates that street vending ice-cream in Dhaka city may not be safe for human consumption.
