| Abstract | The effects of gaseous ozone treatment at refrigeration temperatures, on microbial counts (total aerobic mesophilic heterotrophic microorganisms and inoculated Escherichia coli) in culture media and in beef samples were analyzed. The influence of ozone on beef quality properties such as surface color and rancidity was measured. <br> <br>The effect of gaseous ozone (154 x 10(-6) kg m(-3)) in culture media inoculated with E. coli after 3- or 24-h treatment at 0 and 4 degrees C caused a total inactivation of this microorganism. <br> <br>For beef samples treated with the same gaseous ozone concentration, the highest microbial inhibition was observed at 0 degrees C and after 24-h exposure, producing a decrease of 0.7 and 2.0 log(10) cycles in E. coli and total aerobic mesophilic heterotrophic microorganism counts respectively; however, both the surface color and lipid oxidation of these beef samples were unacceptable. Shorter exposure times (3 h) to the tested ozone concentration at both temperatures (0-4 degrees C), reduced 0.5 log(10) cycles the counts of total aerobic mesophilic heterotrophic microorganisms and 0.6-1.0 log(10) cycles the counts of E. coli, without changing the color or producing rancidity in beef.
