Method for reducing contamination of indigenous cattle carcasses during slaughtering

Abstract EN

e bacteriological study was carried out to evaluate the degree of fbntamination in indigenous cattle carcasses in slaughterhouse, in MfSKhartoum State, during April 2009 - June 2009.

For the total viable •i ^counts (TVCs), 768 swab samples were collected from 32 carcasses, pr-Sterilization by hot tap water (82 'C) to worker's hands and their knives -jwas applied in all slaughtering operations.

The mean total viable count — (TVCs) after skinning, evisceration and washing operations at brisket site were 1.4 ± 0.12, 1.5 ± 0.09 and 1.5± 0.06 logio CFU (colony forming unit) /cm2, in the shoulder site were, 1.3 ± 0.09, 1.2 ± 0.11 and 1.1 ± 0.05 logio CFU/cm2, in the neck site were 1.7 ± 0.05, 1.4 ± 0.06 and 1.6 ± 0.06 logio CFU/cm2 whereas in the rump site the TVCs in these operations were 1.4 ± 0.06, 1.1 ± 0.07, and 1.2 ± 0.10 logio CFU/cm2, respectively with statistically significant difference (P<0.05).

Also there were reduction in TVCs of worker's hands and their knives with statistically significant difference (P<0.05).
