Abstract

A study was conducted to assess the organoleptic and microbiological quality of pizzas sold in various outlets in and around Greater Hyderabad Municipal Corporation Telangana State, India. The sensory scores were higher for reputed brands, least for street vendors and in between for moderate fast food shops. The total viable count was highest (8.8 10⁶CFU/gm) in burgers from street vendors, lowest (3.0 10⁵CFU/gm) from reputed brands, whereas it is intermediate (3.56 ⁶CFU/gm) from moderate fast food centers. The coliforms count and faecal coliform in

A study was conducted to assess the organoleptic and microbiological quality of pizzas sold in various outlets in and around Greater Hyderabad Municipal Corporation Telangana State, India. The sensory scores were higher for reputed brands, least for street vendors and in between for moderate fast food shops. The total viable count was highest (8.8 10⁶CFU/gm) in burgers from street vendors, lowest (3.0 10⁵CFU/gm) from reputed brands, whereas it is intermediate (3.56 ⁶CFU/gm) from moderate fast food centers. The coliforms count and faecal coliform in the burgers collected from reputed brands, moderate fast food centers and street vendors was4.0 10³ and 1.2 ,4.2 10⁴ and 2.1 10⁴and 4.8 10⁴ and 9.8 10³CFU/gm respectively. The yeast and moulds counts were 1.9 10⁴, 2.6 ⁵and 2.0 10⁶CFU/gm in samples from reputed brands, moderate fast food centres and street vendors respectively. The incidence and counts of Staphylococcus spp., E. coli, Salmonella spp., Vibrio spp. and Listeria spp. were also noted.
