Abstract

RODRIGUES, Kelly Lameiro et al. Hygienic-sanitary conditions of street foods from Pelotas, RS. Ciênc. Tecnol. Aliment. [online]. 2003, vol.23, n.3, pp.447-452. ISSN 0101-2061.  http://dx.doi.org/10.1590/S0101-20612003000300026.

Street-vending of ready-to-eat (RTE) foods can be a risk to the consumers health, since people usually involved in this activity does not have proper knowledge in safe handling of foods. Despite this, only a few studies have been made on the microbiological quality of these foods and places where they are prepared. In this paper we report on the higienic-sanitary quality of hot-dogs sold by street-vendors from Pelotas,RS. Samples of hot-dogs, water and work surfaces, were collected from 60 street-vending places and taken to the laboratory for analysis. Counts of aerobic mesophilic bacteria (TPC), Staphylococcus coagulase positive (SCP), total coliforms (TC) and coliforms at 45ºC (FC) were made on samples of hot-dogs. SPC, TC and FC counts were made on the water and surface samples. Among the 60 samples of hot-dogs 53%, 48%, 37% and 25% were found unsatisfactory for TC, TPC, STA and FC, respectively. Only 3 (5%) water samples were found unsatisfactory according to the TPC standard used, and 27% and 23% did not read the standards for TC and FC. Regarding the surfaces, 70% were found unsatisfactory for TPC, 68% for TC and 67% for FC. Salmonella sp was not detected in any of the samples tested. These results suggest that the hygiene practices of many food street-vending places are not adequate, resulting in a high proportion of read-to-eat RTE) foods with microbiological quality unsatisfactory for consumption.

Keywords : street-vending; microbiological quality; hot-dogs.
