title: Heat resistance of Listeria monocytogenes.
abstract: Raw milk was inoculated with Listeria monocytogenes and heat at 69 degrees C to 73 degrees C. The organism was recovered from 46.6% of the heated samples, but not from samples heated at 73 degrees C, after variable periods at refrigeration temperature. The results suggest that a low number of listeriae survive thermal treatments, but cold enrichment is necessary to repair the thermally injured cells.
