<p>A study was conducted to find the potential sources of microorganisms that are found on cull cow hides and to investigate the entry/contamination points of pathogens on the carcass during the slaughter/dressing process. Eighty cull cows were slaughtered over a 4 day period. Fresh fecal samples and hide surface sponge samples (brisket area) were taken and evaluated for the presence of E. coli O157:H7 and Salmonella. The fecal samples yielded no E. coli O157:H7 or Salmonella. The brisket sponge sample had no E. coli O157:H7 but tested positive for Salmonella at a rate of 13.8 %.</p>
