Behavior of Listeria monocytogenes in reconstituted infant cereals

Listeria monocytogenes may contaminate and grow in reconstituted infant cereals refrigerated or temperature abused before consumption. To assess this risk, a 5-strain composite of the pathogen was inoculated in rice, oatmeal, and wheat-rice-oatmeal infant cereals, hydrated (1/6, w/v) with apple juic...

Description
Summary:Listeria monocytogenes may contaminate and grow in reconstituted infant cereals refrigerated or temperature abused before consumption. To assess this risk, a 5-strain composite of the pathogen was inoculated in rice, oatmeal, and wheat-rice-oatmeal infant cereals, hydrated (1/6, w/v) with apple juice, pasteurized milk (2% fat) or water, and stored at 4, 15, or 25C for 0, 8 and 24 h to simulate potential advance home preparation and abuse. L. monocytogenes survived with minimal (
