The animals were housed at a farm where the bulk raw ewe milk was processed to produce raw milk soft cheese. <jats:italic>List. monocytogenes<\/jats:italic> was shed from the right mammary complex. Shedding was observed over a period of 99 d. A mean level of 4\u00b756\u00d710<jats:sup>4<\/jats:sup> cfu (colony forming units) <jats:italic>Listeria monocytogenes<\/jats:italic>\/ml was recovered from the raw milk originating from the infected udder. The numbers ranged from 9\u00d710<jats:sup>1<\/jats:sup> to 2\u00b795\u00d710<jats:sup>5<\/jats:sup>. The bulk milk was contaminated by approx. 5\u00b77\u00d710<jats:sup>3<\/jats:sup> cfu\/ml. In the cheese product, 2\u00b70\u00d710<jats:sup>2<\/jats:sup> cfu <jats:italic>List. monocytogenes<\/jats:italic>\/g were constantly detectable for a period of 7 d post manufacture. The starter culture used for coagulation had a pivotal influence on the behaviour of <jats:italic>List. monocytogenes<\/jats:italic> during cheesemaking. Using the same mesophilic buttermilk culture as used by the farmer allowed numbers of <jats:italic>Listeria<\/jats:italic> to increase 60-fold within 12 h owing to a delayed acidification of the bulk milk. Addition of a thermophilic yogurt culture reduced the numbers of <jats:italic>Listeria<\/jats:italic> within 8 h of incubation.<\/jats:p>","DOI":"10.1017\/s0022029903006277","type":"journal-article","created":{"date-parts":[[2003,10,16]],"date-time":"2003-10-16T07:55:53Z","timestamp":1066290953000},"page":"395-401","source":"Crossref","is-referenced-by-count":35,"title":["A case of sporadic ovine mastitis caused by <i>Listeria monocytogenes<\/i> and its effect on contamination of raw milk and raw-milk cheeses produced in the on-farm dairy"],"prefix":"10.1017","volume":"70","author":[{"given":"Dagmar","family":"Schoder","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Petra","family":"Winter","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdoulla","family":"Kareem","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Walter","family":"Baumgartner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Wagner","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2003,10,16]]},"container-title":["Journal of Dairy Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0022029903006277","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,6]],"date-time":"2019-05-06T22:24:33Z","timestamp":1557181473000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0022029903006277\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2003,10,16]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2003,11]]}},"alternative-id":["S0022029903006277"],"URL":"https:\/\/doi.org\/10.1017\/s0022029903006277","relation":{},"ISSN":["0022-0299","1469-7629"],"issn-type":[{"value":"0022-0299","type":"print"},{"value":"1469-7629","type":"electronic"}],"subject":[],"published":{"date-parts":[[2003,10,16]]}}}
