Reduction of Escherichia coli on surfaces of utensils and development of a predictive model as a function of concentration and exposure time of chlorine.

摘要: Abstract Cross-contamination to fruit and vegetables can readily occur through contaminated surfaces; thus, there is a need develop methods inactivate microorganisms on the surfaces of various materials. The aim this study was reduce levels Escherichia coli materials predictive model as function chlorine concentration exposure time. reduction E. stainless steel, plastic, wood, rubber, glass, ceramic at concentrations (0–200 ppm) after 0–5-min evaluated. surface treatment maximum (200 ppm) over 5-min reduced contamination 5.30, 5.18, 3.34, 4.69, 5.05, 5.53 log CFU/cm2 ceramic, respectively. Using these results, models for using treatmen...
