Isolates were \nidentified as phage type 4 (PT4). Risk factors and sources of infection were investigated in two \ncase-control studies, a traceback of implicated foods, and environmental testing. Forty-three \npatients with sporadic infections and 86 controls were included in a case-control study of risk \nfactors for infection. A follow-up case-control study of 25 case and 19 control restaurants \npatronized by case and control patients examined risks associated with restaurant practices. In \nthe first case-control study, restaurant dining was associated with illness (<jats:italic>P<\/jats:italic> = 0\u00b7002). In the \nfollow-up case-control study, case restaurants were likelier to use &gt; 2000 eggs per week \n(<jats:italic>P<\/jats:italic> &lt; 0\u00b702), to pool eggs (<jats:italic>P<\/jats:italic> &lt; 0\u00b705), and to use eggs from cooperative \u2018A\u2019 (<jats:italic>P<\/jats:italic> &lt; 0\u00b7009). Eggs \nimplicated in separately investigated SE PT4 outbreaks were traced to cooperative \u2018A\u2019, and SE \nPT4 was cultured from one of the cooperative's five local farms. We conclude that SE PT4 \ntransmitted by infected eggs from a single farm caused a fivefold increase in human infections \nin Utah.<\/jats:p>","DOI":"10.1017\/s0950268899004057","type":"journal-article","created":{"date-parts":[[2002,7,27]],"date-time":"2002-07-27T09:23:42Z","timestamp":1027761822000},"page":"1-8","source":"Crossref","is-referenced-by-count":35,"title":["The pandemic of <i>Salmonella<\/i> Enteritidis phage type 4 reaches \nUtah: a complex investigation confirms the need for \ncontinuing rigorous control measures"],"prefix":"10.1017","volume":"125","author":[{"given":"J.","family":"SOBEL","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.
