چکیده انگلیسی
The hide-to-beef microbial transfer-reducing effects of a novel Shellac treatment of hides (based on “on-hair immobilization” of microorganisms) were evaluated. In the hide-to-meat direct contact laboratory-based experiments, treatment of hides (of varying visual cleanliness) with Shellac produced significant microbial reductions on beef: up to 3.6Â log10 CFU/cm2 of total viable count of bacteria (TVC), up to 2.5Â log10 CFU/cm2 of Enterobacteriaceae (EC) and up to 1.7Â log10 CFU/cm2 of generic Escherichia coli (GEC). In a small commercial abattoir under “bad-case” conditions (slaughtering dirty cattle, inadequate process hygiene), treatment of hides with Shellac produced significant microbial reductions on beef carcasses: 1.7Â log10 CFU/cm2, 1.4Â log10 CFU/cm2 and 1.3Â log10 CFU/cm2 of TVC, EC and GEC, respectively. In both laboratory- and abattoir-based trials, TVC reductions on beef achieved by the Shellac hide treatment were superior to those achieved by the comparative sanitizer rinse-vacuum hide treatment, but reductions of EC and GEC did not differ significantly between the two hide treatments.
