ABSTRACT
Listeria innocua M1 was developed as a thermal processing indicator organism for L. monocytogenes by selection of a rifampin- and streptomycin-resistant mutant. zetaD values were 5.6 and 5.8 degrees C, and D (68 degrees C) values were 3.8 and 4.9 s for L. monocytogenes and L. innocua, respectively, in skim milk. The advantages of easy selection, similar heat resistance, and nonpathogenicity make L. innocua M1 appropriate for challenge studies designed to evaluate process lethality with respect to L. monocytogenes.
