Hypothesis generating interviews pointed toward ready-to-eat chicken salad from a Finnish company and at the same time Estonian authorities informed of a<jats:italic>S. enteritidis<\/jats:italic>PT 1B outbreak linked to chicken wrap prepared at an Estonian restaurant. We found that chicken salad was associated with the infection (odds ratio (OR) 16\u00b71, 95% confidence interval (CI) 1\u00b77\u2013148\u00b77 for consumption and OR 17\u00b75. 95% CI 4\u00b70\u201376\u00b70 for purchase). The frozen pre-cooked chicken cubes used in Finnish salad and in Estonian wraps were traced back to a production plant in China. Great Britain made two Rapid Alert Systems for Food and Feed notifications on chicken cubes imported to the UK from the same Chinese production plant. Microbiological investigation confirmed that the patient isolates in Estonia and in Finland were indistinguishable from the strains isolated from chicken cubes in Estonia and in the UK. We recommend that despite certificates for tested<jats:italic>Salmonella<\/jats:italic>, food items should be analyzed when<jats:italic>Salmonella<\/jats:italic>contamination in outbreak investigations is suspected. In outbreak investigations, electronically implemented case\u2013case study saves time, effort, and money compared with case\u2013control study.<\/jats:p>","DOI":"10.1017\/s0950268817001364","type":"journal-article","created":{"date-parts":[[2017,8,3]],"date-time":"2017-08-03T09:34:52Z","timestamp":1501752892000},"page":"2727-2734","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":22,"title":["Outbreak of<i>Salmonella enteritidis<\/i>phage type 1B associated with frozen pre-cooked chicken cubes, Finland 2012"],"prefix":"10.1017","volume":"145","author":[{"given":"S.","family":"HUUSKO","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"PIHLAJASAARI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"SALMENLINNA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J.","family":"S\u00d5GEL","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.","family":"DONT\u0160ENKO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"E.","family":"DE PINNA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H.","family":"LUNDSTR\u00d6M","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.","family":"TOIKKANEN","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.","family":"RIMHANEN-FINNE","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2017,8,3]]},"reference":[{"key":"S0950268817001364_ref9","unstructured":"European Society of Clinical Microbiology and Infectious Diseases.
