Interpretive Summary:

Technical Abstract: Bacterial cross-contamination from the haired outer surface of cattle skins to the inner meat and hide quality detrition from bacteria is recognized as a severe hygienic problem for commercial beef and hide processing facilities. To circumvent bacterial contamination, cattle are washed during hide procurement and meat processing with surfactants and/or antimicrobials known to be safe for consumers. This study investigated the efficacy of spray wash treatment on three regions (head, belly and butt) of the outer haired surface of a beef cattle hide with two such formulations, Citrilow™ and Cecure™ . Both Citrilow™ and Cecure™ independently showed ability to reduce bacterial concentrations on freshly procured hides. Spray washing with Citrilow™ affectively reduced the aerobic bacterial recovery by 2.78 - 2.95 log cycles, 2.42 - 2.78 log cycles and 3.32 - 3.72 log cycles on the head, belly and butt regions respectively. Additionally, after spray washing with Citrilow™ Enterobacteriaceae recovery counts reduced by 3.06 - 4.08 log cycles, 2.14 - 2.57 log cycles, and 4.65 - 4.99 log cycles on the head, belly and butt regions, respectively. Similarly, Cecure™ significantly lowered aerobic bacterial levels on the head, belly and butt regions by 1.40 - 1.65 log cycles, 6.00 - 6.12 log cycles and 4.26 - 3.60 log cycles. Spray washing with Cecure™ significantly lowered Enterobacteriaceae counts by 3.65 - 3.01 log cycles, and 2.17 - 3.17 log cycles on belly and butt regions. Additionally, physical and mechanical tests revealed no damaging effects on crust leather produced from the treated hides with either formulation. The results from this study demonstrate that a Citrilow™ or Cecure™ spray is an effective antimicrobial agent during cattle beef and hide processing.
