With the name of Soup, the elaborated nutritional conserve with
broths is designated. Clostridium perfringens is an important pathogen
agent which causes, among others, enteritis in humans and
enterotoxemia in domestic animals. The aim of this work was to
establish the microbiological quality of dehydrated soups expended
in San Luis' city. Fifty and nine samples of dehydrated soups
were processed, acquired in trade of it expended the public in San
Luis' city. The following determinations were carried out:
count of total aerobes in agar medium count, coliforms count in
Mac Conkey broth and EC broth (MPN), count of C. perfringens
in milk iron medium (MPN), determination of C. perfringens in
agar triptosa sulfite cycloserine (TSCA) and determination of
enterotoxigenic strains of C. perfringens by RPLA. Total aerobe
counts in the 59 samples were 102 -104 cfu/g. Coliforms were detected
in an only sample. C. perfringens was detected in 19 (63,33%)
samples. None enterotoxigenic strain was obtained. This 19 samples
gave counts <3.0-43 C. perfringens/g by the MPN method, 3
samples surpasses the limits suggeted by the Alimentary Code
(CAA) (Art 442). The microbiological quality in general was good
but the incidence of C. perfringens in this samples was low a potential
risk exists, in the event of improper handing during the preparation
of the foods.
