Inactivation Kinetics of <i>Listeria monocytogenes</i> on Hard-Cooked Eggs Treated with Organic Acids.

ABSTRACT: Peeled hard-cooked eggs (HCEs) are a popular and convenient choice for consumers and food servicers. A recent outbreak and several recalls of HCEs have highlighted their susceptibility to contamination with Listeria monocytogenes. HCEs are generally treated with antimicrobials, such as citric acid, to enhance the safety and quality of the product. A 2019 multistate outbreak linked to consumption of contaminated HCEs in the U.S. prompted research on the effectiveness of citric acid, and other organic acids, to control L. monocytogenes on this food product. This study therefore assessed the use of organic acids as antimicrobials against L. monocytogenes on HCEs. HCEs were dip-inoculated with L. monocytogenes, resulting in an initial concentration of ca. 8 log CFU/
