Summary

The effect of prestorage treatments, such as immersion in a sorbate solution (5%, wt/vol), heating (60 °C, 1 minute), and a combination of the two treatments, and the subsequent storage in air or under modified atmosphere packaging (MAP; 40% CO2, 30% O2 and 30% N2) at chill temperatures (0 plus or minus 1 °C), on Listeria monocytogenes and Salmonella Enteritidis PT4 was studied. The prestorage treatments affected the pathogenic bacteria, and in all cases, there was a decrease in their population, with the sorbate hot water combination treatment being most affective. The beneficial effect of the prestorage treatments, which was more pronounced in storage under MAP conditions, suggests an interaction of the treatments with the CO2 of MAP against injured bacterial cells.
