In turn, this environmental contamination can become the source of food- and feed-borne illnesses in humans and animals, with the food production chain representing a continuum between the farm environment and human populations that are susceptible to listeriosis. Here, we update a review from 2012 and summarize the current knowledge on the asymptomatic carrier statuses in humans and animals. The data on fecal shedding by species with an impact on the food chain are summarized, and the ways by which asymptomatic carriers contribute to the risk of listeriosis in humans and animals are reviewed.<\/jats:p>","DOI":"10.3390\/foods11213472","type":"journal-article","created":{"date-parts":[[2022,11,2]],"date-time":"2022-11-02T06:49:02Z","timestamp":1667371742000},"page":"3472","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":59,"title":["Asymptomatic Carriage of Listeria monocytogenes by Animals and Humans and Its Impact on the Food Chain"],"prefix":"10.3390","volume":"11","author":[{"given":"Dagmar","family":"Schoder","sequence":"first","affiliation":[{"name":"Department of Veterinary Public Health and Food Science, Institute of Food Safety, University of Veterinary Medicine, 1210 Vienna, Austria"},{"name":"Veterinarians without Borders Austria, 1210 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia","family":"Guldimann","sequence":"additional","affiliation":[{"name":"Department of Veterinary Sciences, Faculty of Veterinary Medicine, Institute of Food Safety and Analytics, Ludwig-Maximilians-University Munich, 85764 Oberschlei\u00dfheim, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3390-8173","authenticated-orcid":false,"given":"Erwin","family":"M\u00e4rtlbauer","sequence":"additional","affiliation":[{"name":"Department of Veterinary Sciences, Faculty of Veterinary Medicine, Institute of Milk Hygiene, Ludwig-Maximilians-University Munich, 85764 Oberschlei\u00dfheim, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"(2021).
