| Résumé : |
Bacterial contamination on the outer grained hide of cattle serves as a significant challenge to the meat and bide processing plants regarding food safety. Cattle serves as a host to several bacteria including pathogens, which may become firmly lodged on a cattle's bide during their lifespan and can facilitate cross contamination of the underlying meat and meat processing equipment in a slaughterhouse. In this study, the efficacy of sodium dichloroisocyanurate dehydrate (SDCIC), which belongs to N-halamine group of compounds is evaluated on inhibition of the natural-borne bacteria from the haired surface of cattle bide. Spray-washing with 0.25%, 0.50% and 0.75 % aqueous SDCIC solutions reduced total aerobic bacteria on hide surface by 1.6 and 2.37 and 3.57 log CFU/50 cm'respectively in 5 min. Similarly, in comparison with water spray, a 5 min treatment with 0.25, 0.50 and 0.75 % SDCIC resulted in a reduction of Enterobacteriaceae (ENT) and related gram-negative bacilli (gnEB) counts by 1.2, 2.22 and 4.22 log CFU/50 cm' respectively. The highest reduction of E. coli recovery of 1.48 log CFU/50 cm2 was obtained with a spray treatment of 0.75 % SDCIC in 1 minute. Likewise, 0.75 % SDCIC spray treatment resulted in 2.5 and 3.65 log CFU/50 cm2 reduction of Salmonella in 1 and 5 min, respectively in comparison to their respective controls. Leather from treated hides was tested to evaluate the effects of N-halamine solutions on structural, mechanical and subjective properties of produced leather in which no major detrimental impacts were found. |
