Concentration exponents for the broad spectrum antimicrobial Virkon were determined for Listeria monocytogenes using both plate counts and bioluminescence measurements; the values of 3.15 and 2.6 indicate a close equivalence between these two measurement procedures. Virkon is an effective biocide for L. monocytogenes at the manufacturer's in‐use concentration of 1%.
