RESUMO
Standard enrichment, plating, and biochemical techniques were used to assess the incidence of Salmonella species on beef and pork carcasses and processed meat products. The incidence of Salmonella in pork carcasses was 56% and in beef carcasses, 74%. These figures are about the same as previously reported for pork but much higher than previously reported for beef carcasses; however, they represent only three to five abattoirs in Georgia and do not necessarily represent contamination levels throughout the country. Examination of carcasses by area did not indicate greater incidence of Salmonella in any one area. Two areas suggested for representative sampling are the cervical and anal areas of the carcass. Of the sausage samples examined, 38% of the fresh pork sausage, 9% of the smoked pork sausage, and 1 sample (souse) of 16 samples of miscellaneous sausage products were contaminated. Examination of subsamples indicated that Salmonella, when present in sausage products, could be found in any section of the entire sample.
