Summary

The germicidal efficacy of three common sanitizers (quaternary ammonium compound, iodophor, and chlorine) on Listeria (L. monocytogenes V7, L. monocytogenes Scott A, L. ivanovii, and L. innocua) was studied using the suspension test method at various exposure temperatures (2-25 deg C) and times (0.5-1.5 minutes). The quaternary ammonium compound, iodophor, and chlorine solutions were prepared with sterile deionized water at concentrations of 25-200, 12.5-50, and 25-200 ppm, respectively. All three sanitizers were effective against Listeria at 25 deg C regardless of their concentrations.
