Growth curves of TVC on untreated (▲) or HPP–treated (500 MPa/10 min) (♦) chicken fillets and of L. monocytogenes on untreated (x) or HPP–treated (500 MPa/10 min) (■) chicken fillets inoculated with low, medium, and high inoculum level of a 4-strain cocktail of Listeria monocytogenes and stored under vacuum package at 4 °C (left) and at 12 °C (right). Open symbols (□) indicate absence of the pathogen after applying the enrichment method. Vertical red dotted line: end of the control samples shelf-life according to sensory analysis. Vertical blue dashed line: end of the HPP-treated samples shelf-life according to sensory analysis. Error bars represent the mean values ± standard deviation.
