Abstract

This study investigated spray wash treatments independently with Citrilow or Cecure for their effects on microbial concentrations and leather quality. Spray washing with Citrilow reduced aerobic mesophilic recovery by 2.42–2.78 log cycles 2.78–2.95 log cycles, and 3.32–3.72 log cycles on the belly, belly, and butt regions, respectively. After washing with Citrilow, Enterobacteriaceae/related gram‐negative enteric bacilli (ENT/gnEB) recovery counts reduced by, 2.14–2.57 log cycles, 3.06–4.08 log cycles, and 4.65–4.99 log cycles on the belly, head, and butt regions, respectively. Cecure significantly lowered aerobic bacterial levels on the belly, head, and butt regions by 6.00–6.12 log cycles, 1.40–1.65 log cycles, and 4.26–3.60 log cycles, respectively. Washing with Cecure significantly lowered ENT/gnEB counts by 3.65–3.01 log cycles and 2.17–3.17 log cycles on belly and butt regions. Subjective testing, grain structure analyses, and mechanical properties of leather made from fresh hides after Citrilow or Cecure treatments revealed no difference between the treatment and their corresponding controls.
