Different species of Pseudomonas bacteria are found in abundance in nature. Although they are weak pathogens but they have great importance in the food hygiene and health because they are psychrophilic bacteria and can grow and proliferate at refrigerated temperatures and can produce proteolytic and lipolysis enzymes. In this study, the simultaneous effect of different doses of microwave radiation and different concentrations of lactic acid and salt on Pseudomonas aeruginosa bacteria inoculated into veal parts were studied. In this study, 108 specimens were evaluated in 9 treatments per day, 0,3,6,9, 12 15. And after refrigerating, microbial tests performed including Pseudomonas aeruginosa count and TVN chemical test. The control group was treated with distilled water. The bacterial count was done in Pseudomonas Agar medium. The effect of various concentrations of acid, salt, and microwave time on the logarithm of the bacterial count was evaluated over a 15-day refrigerator by Mixed repeated measure Anova. The results showed that different concentrations of acid, salt and microwave time and their interactions had a significant effect on the mean logarithm number of bacteria during refrigerating period.
