[Microbiological quality of street-vendor ice cream in Dakar].
During a multicenter study initiated by the International Network of Pasteur Institutes and Associated Institutes, microbiological quality of street-vended ice creams in Dakar was evaluated. 313 samples of ice creams from 170 street-vendors were collected and tested for common foodborne pathogens and indicator organisms. Results showed that microbiological quality of 45% of tested samples was unsatisfactory because of large populations of aerobic mesophilic organisms (36.7%), thermotolerant coliforms bacteria (21.4%) and sometimes E. coli. (10.6%). Strict pathogens as Salmonella, Shigella and Vibrio cholerae were not found. An investigation conducted among vendors showed a lack of education and training; these vendors need information about food preparation and storage practices that reduce microbiological contamination of foods.
