Salmonelas en la carne de consumo molida

Abstract

Four hundred and thirty-four samples of chopped meat were examined for Salmonella serotypes; of these, 244 samples came from five rural butcher shops in the Barba Canton, and 190 from five butcher shops in the capital city of San José, in Costa Rica

Micro-organisms of the genus Salmonella were isolated from 40 (9,2 percent) of the samples. More samples from butcher shops in the city (17,9 percent positive) proved to be contaminated than from the rural butcher shops (2,5 percent positive). Possible causes of this differences are discussed

In all, 43 strains were isolated, and 10 serotypes identified, predominant among them being S. anatum and S. derby; the significance of this finding is discussed. Three samples were contaminated with two Salmonella serotypes, and Shigella boydii 5 was isolated from another(AU)
