L. monocytogenes can grow at refrigeration temperatures and is of particular concern for ready-to-eat foods that require refrigeration. There is substantial interest in conducting and modeling shelf-life studies on L. monocytogenes, especially relating to storage temperature. Growth model parameters are generally estimated from constant-temperature growth experiments. Traditionally, first-order and second-order modeling (or primary and secondary) of growth data has been done sequentially. However, omnibus modeling, using a mixed-effects nonlinear regression approach, can model a full dataset covering all experimental conditions in one step. This study compared omnibus modeling to conventional sequential first-order\/second-order modeling of growth data for five strains of L. monocytogenes. The omnibus model coupled a Huang primary model for growth with secondary models for growth rate and lag phase duration. First-order modeling indicated there were small significant differences in growth rate depending on the strain at all temperatures. Omnibus modeling indicated smaller differences. Overall, there was broad agreement between the estimates of growth rate obtained by the first-order and omnibus modeling. Through an appropriate choice of fixed and random effects incorporated in the omnibus model, potential errors in a dataset from one environmental condition can be identified and explored.<\/jats:p>","DOI":"10.3390\/foods10051099","type":"journal-article","created":{"date-parts":[[2021,5,16]],"date-time":"2021-05-16T23:17:16Z","timestamp":1621207036000},"page":"1099","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Omnibus Modeling of Listeria monocytogenes Growth Rates at Low Temperatures"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8752-3231","authenticated-orcid":false,"given":"Vincenzo","family":"Pennone","sequence":"first","affiliation":[{"name":"Teagasc Food Research Centre, Moorepark, Fermoy, P61 C996 Co Cork, Ireland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8462-9775","authenticated-orcid":false,"given":"Ursula","family":"Gonzales-Barron","sequence":"additional","affiliation":[{"name":"Centro de Investiga\u00e7\u00e3o de Montanha (CIMO), Instituto Polit\u00e9cnico de Bragan\u00e7a, Campus de Santa Apol\u00f3nia, 5300-253 Bragan\u00e7a, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7937-7617","authenticated-orcid":false,"given":"Kevin","family":"Hunt","sequence":"additional","affiliation":[{"name":"UCD School of Biosystems and Food Engineering, University College Dublin, Belfield, Dublin 4, Ireland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3077-7414","authenticated-orcid":false,"given":"Vasco","family":"Cadavez","sequence":"additional","affiliation":[{"name":"Centro de Investiga\u00e7\u00e3o de Montanha (CIMO), Instituto Polit\u00e9cnico de Bragan\u00e7a, Campus de Santa Apol\u00f3nia, 5300-253 Bragan\u00e7a, Portugal"}]},{"given":"Olivia","family":"McAuliffe","sequence":"additional","affiliation":[{"name":"Teagasc Food Research Centre, Moorepark, Fermoy, P61 C996 Co Cork, Ireland"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3925-5863","authenticated-orcid":false,"given":"Francis","family":"Butler","sequence":"additional","affiliation":[{"name":"UCD School of Biosystems and Food Engineering, University College Dublin, Belfield, Dublin 4, Ireland"}]}],"member":"1968","published-online":{"date-parts":[[2021,5,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"EFSA (2019).
