Abstract
This current study was carried out to evaluate the effect of trisodium phosphate 5%, 8% and 10%, chlorine 20 ppm,50ppm
and 60ppm and hydrogen peroxide 1%, 2% and 3%, on total aerobic plate count, Enterobactereacea count,
staphylococcus count and isolation percentages of Salmonella spp, Staphylococcus aureus and L. monocytogens of fresh
slaughtered chicken. The results of count of control sample were 8.2±7.99, 4.41±3.89 and 4.30±3.76 log10cfu/g and the
percentages of isolation were 60, 90 and 10%, respectively. While after dipping in trisodium phosphate 5%, 8% and 10%,
the reduction percentage of aerobic plate count, Enterobactereacea count and staphylococcus count were 6.2%, 23%,
30.6%, 11.1%, 44%, 100% , 17.2%, 32.3% and 52%, after dipping in chlorine 20ppm, 50ppm and 60ppm,were 4%, 5%,
35.3%, 9.3%, 22.6%, 27.2%, 8.1%, 30.2% and 32.6%, after dipping in hydrogen peroxide 1%, 2% and 3%, were80.8%,
82.3% , 87.8%, 82.7%, 86.8%, 100%, 82.5%, 100% and 100%, respectively. Moreover, the reduction percentages of
Salmonella spp., Staphylococcus aureus, were 50%, 66.7%, 83.3%, 22.2%, 66.6% and 100%, after dipping in trisodium
phosphate 5%, 8% and 10%. While after dipping in chlorine 20ppm,50ppm and 60ppm, were16.7%, 33.3%, 50%, 11.1%,
22.2% and 33.3% and after dipping in hydrogen peroxide 1%, 2% and 3%, were50%, 66.6%, 83.3%, 55.5%, 100% and
100%. L. monocytogenes failed to be detected (100% decontamination)
