TL;DR:
It is shown that listeria monocytogenes can persistently contaminate food processing environments and tolerate sanitizers, and a diverse panel of 83 strains from 1926 to 1964 are reported.

ABSTRACT
Listeria monocytogenes
can persistently contaminate food processing environments and tolerate sanitizers. Most sequenced strains are from clinical and environmental sources in the contemporary era, with relatively few prior to extensive food processing and sanitizer use. We report the genome sequences of a diverse panel of 83 strains from 1926 to 1964.
