In this context, ready-to-eat (RTE) foods of animal and plant origin are of particular relevance as the source of infection. In Germany, the official food and veterinary control laboratories, under the sovereignty of the federal states, examine foodstuffs for the presence of foodborne pathogens, including\n                    <jats:italic toggle=\"yes\">Listeria<\/jats:italic>\n                    .

Overall, the official control laboratories achieved excellent results in the PTs. In total, 91 participants were documented. Flawless results were reported in 93.4% of the cases. Only four times, participants did not pass the PT in the first attempt. By performing official food and veterinary controls along the food chain, control laboratories make a significant contribution to food safety. To keep the excellent standard of the official control laboratories in Germany in line with future challenges in food safety, PTs with relevant RTE food matrices are indispensable.\n                  <\/jats:p>","DOI":"10.1089\/fpd.2024.0156","type":"journal-article","created":{"date-parts":[[2025,5,23]],"date-time":"2025-05-23T07:50:33Z","timestamp":1747986633000},"page":"883-892","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Retrospective Analysis of the Results of Five Consecutive Proficiency Tests Organized by the German National Reference Laboratory for\n                    <i>Listeria monocytogenes<\/i>"],"prefix":"10.1177","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4779-5424","authenticated-orcid":false,"given":"Christoph-Martin","family":"Ufermann","sequence":"first","affiliation":[{"name":"Department of Biological Safety, Unit Product Hygiene and Disinfection Strategies, German Federal Institute for Risk Assessment, Berlin, Germany."},{"name":"Department 1\u2014Infectious Diseases, Robert Koch Institute, Berlin, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marlen","family":"Adler","sequence":"additional","affiliation":[{"name":"Department of Biological Safety, Unit Product Hygiene and Disinfection Strategies, German Federal Institute for Risk Assessment, Berlin, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stefanie","family":"L\u00fcth","sequence":"additional","affiliation":[{"name":"Department of Biological Safety, Unit Product Hygiene and Disinfection Strategies, German Federal Institute for Risk Assessment, Berlin, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sascha","family":"Al Dahouk","sequence":"additional","affiliation":[{"name":"Department of Biological Safety, Unit Product Hygiene and Disinfection Strategies, German Federal Institute for Risk Assessment, Berlin, Germany."},{"name":"Department 1\u2014Infectious Diseases, Robert Koch Institute, Berlin, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sylvia","family":"Kleta","sequence":"additional","affiliation":[{"name":"Department of Biological Safety, Unit Product Hygiene and Disinfection Strategies, German Federal Institute for Risk Assessment, Berlin, Germany."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,5,23]]},"reference":[{"key":"e_1_3_5_2_1","doi-asserted-by":"publisher","DOI":"10.1128\/MRA.00267-20"},{"key":"e_1_3_5_3_1","doi-asserted-by":"publisher","DOI":"10.17590\/20210311-115317"},{"key":"e_1_3_5_4_1","volume-title":"BVL-Report 9.4 Reports on food safety","author":"BVL","year":"2015","unstructured":"BVL.
