Abstract:

his study was conducted to evaluate the efficacy of three decontaminators in reducing the level of contamination in chicken carcasses which had been artificially contaminated. A grand total of forty random samples of raw chicken carcasses were purchased directly from local markets. Chicken samples were then dipped in cultures of the tested microorganisms (Salmonella spp., Staphylococcus aureus, E.coli O157:H7 and L. monoctogens) (10 samples for each microorganism). Then dipped into containers containing distilled water (control) , chlorine 30 ppm, 50 ppm and 70 ppm, trisodium phosphate 3%, 5% an 8% and lactic acid 0.75%, 1.25% and 2% , where the reduction percentage of Salmonella were 26.02 %, 26.57 %, 29.16 %, 34.88% , 36.78 %, 38.01 %, 35.42 %, 40.87 % and 54.50 %, respectively, compared to control. while the reduction of Listeria monocytogenes was 16.64 %, 20.60% , 30.43% , 21.74 %, 21.74 %, 25.14 %, 22.87 %, 30.24 % and 39.89 % respectively . Moreover , the reduction percentages of S. aureus was 14.29 %, 15.70 %, 19.58% , 8.11 %, 10.58 %, 27.69 %, 17.28 %, 21.34 % and 27.87 % , respectively . Finally, the reduction percentage of E.coli O157:H7 was 9.56 %, 16.61 %, 20.47 %, 17.45%, 21.48 %, 27.85 %, 18.12%, 19.97% and 29.70 %, respectively.
