The food safety challenges derived from the market demands towards convenient food, such as ready-to-eat meat products with extended durability, motivate food business operators to explore and adopt new intervention strategies to increase the microbiological safety of their products. This thesis was focused on assessing and modelling the behaviour of Listeria monocytogenes and Salmonella towards different intervention strategies with the aim to develop decision support systems to increase the microbiological safety and to extend the safe shelf-life of different RTE meat products. Several challenge tests and predictive microbiological approaches were applied to characterize the behaviour of Listeria monocytogenes and Salmonella in RTE meat products in response to antimicrobial and post-lethality intervention strategies aiming (i) to inhibit the growth of L. monocytogenes on cooked ham, including biopreservation and modified atmosphere packaging (MAP) and (ii) to inactivate L. monocytogenes and/or Salmonella in raw pet food, cooked ham, dry-cured ham and/or dry-fermented sausages, including high pressure processing (HPP) or corrective storage. Moreover, the potential interactions between HPP and antimicrobial strategies were also assessed. ​
