Hygienic sanitary conditions of vacuum packed beef produced by slaughterhouses qualified for export in the Mato Grosso state, Brazil
ABSTRACT: Brazil is the largest exporter of beef of the world and Mato Grosso State is the highest beef producer in this country. To maintain product competitiveness and market expansion, sanitary hygienic control of the entire process is indispensable to ensure the attainment of harmless beef and quality. The objective of this study was to evaluate the hygienic sanitary conditions of vacuum-packed beef produced by establishments qualified for export in the state of Mato Grosso, Brazil. A total of 60 samples were submitted to coliforms counts at 35°C and at 45°C and E. coli. The mean contamination by at 35°C and coliforms at 45°C were 3,1 x 102MPN/g and 7.7MPN/g respectively. The presence of E. coli was verified in five samples, representing an occurrence of 8.3% (5/60), and Salmonella spp. in 5% (03/60) of the analyzed samples. The MPN (Most Probable Number) average of coliforms at 35°C and 45°C are in accordance to national and international legislation; however, the presence of Samonella spp., E. coli in some sample indicates a low risk of occurrence of salmonellosis and colibacillosis transmitted by the evaluated beef. However, transmission risk of these diseases cannot be ruled out, since the presence of E. coli does not depend on the amount of coliforms and national legal standards established for the group of thermotolerant coliforms.
