A Quantitative Risk Assessment Model for Listeria monocytogenes in Ready-to-Eat...
Guillier, Laurent; Gonzales-Barron, Ursula; Pouillot, Régis; Mota, Juliana De Oliveira; Allende, Ana; Kovacevic, Jovana; Guldimann, ClaudiaThis study introduces a farm-to-fork quantitative risk assessment (QRA) model for invasive listeriosis from ready-to-eat diced cantaloupe. The modular model comprises seven stages-preharvest (soil and irrigation contamination), harvest (cross-contamination and survival), pre-processing (brushing), processing (flume tank washing, dicing and equipment cross-contamination), lot testing, cold-chain transport and re...

Gonzales-Barron, Ursula; Pouillot, Régis; Skjerdal, Taran; Carrasco, Elena; Teixeira, Paula; Stasiewicz, Matthew J.; Hasegawa, AkioThis study introduces a quantitative risk assessment (QRA) model aimed at evaluating the risk of invasive listeriosis linked to the consumption of ready-to-eat (RTE) smoked and gravad fish. The QRA model, based on published data, simulates the production process from fish harvest through to consumer intake, specifically focusing on smoked brine-injected, smoked dry-salted, and gravad fish. In a reference scenar...
A Quantitative Risk Assessment Model for Listeria monocytogenes in Non-Ready-to...
Gonzales-Barron, Ursula; Pouillot, Régis; Mota, Juliana de Oliveira; Hasegawa, Akio; Allende, Ana; Dong, Qingli; Stasiewicz, Matthew J.A quantitative risk assessment (QRA) model was developed to evaluate the risk of invasive listeriosis from the consumption of non-ready-to-eat (non-RTE) frozen vegetables. On a lot basis, the QRA model simulates Listeria monocytogenes concentration and prevalence in a “Processing module” that comprises blanching, potential recontamination and packaging, any post-packaging inactivation treatment, and within-lot ...
Updated Parameters for Listeria monocytogenes Dose–Response Model Considering P...
Pouillot, Régis; Kiermeier, Andreas; Guillier, Laurent; Cadavez, Vasco; Sanaa, MoezBetter knowledge regarding the Listeria monocytogenes dose-response (DR) model is needed to refine the assessment of the risk of foodborne listeriosis. In 2018, the European Food Safety Agency (EFSA) derived a lognormal Poisson DR model for 14 different age-sex sub-groups, marginally to strain virulence. In the present study, new sets of parameters are developed by integrating the EFSA model for these sub-group...
