Abstract

The aim of this work was to evaluate the sanitary condition of different kinds of fruits
pulps merchandized in the popular free markets of the city of São Luís-MA, Brazil.
Analysis of the following bacteria were performed: coliforms at 45ºC, Salmonella
sp., Staphylococcus positive coagulase, as well as the presence of moulds and
yeast in 40 pulp samples purchased at the cited markets. Results showed the
absence of Salmonella sp. and Staphylococcus positive coagulase. Nevertheless
100% were contaminated by moulds and yeast and 12% contaminated by coliforms
at 45°C. Some strains of human pathogenic enterobacteria were identified, such as
Escherichia coli, Enterobacter aerogenes, Klebsiella pneumoniae, Citrobacter
freundii, Erwinia uredovora and Proteus mirabilis.
