In December 2023, notifications of cryptosporidiosis cases increased in Sweden, prompting the initiation of a national outbreak investigation, and a case\u2013control study was performed to identify the source. We identified 60 cases between 15 December 2023 and 1 January 2024. The median age was 44\u00a0years (range: 16\u201381), and 73% were women. Controls were recruited from a national random pool; frequency was matched by age group and sex. Compared to controls, cases were more likely to have consumed items from salad bars in grocery stores (8% vs. 85%; adjusted odds ratios [aOR]: 58; 95% confidence interval [CI]: 22\u2013186). In regards to food items from the salad bars, cases were more likely to have consumed kale mix salad compared to controls (62% vs. 32%; aOR: 3.6; 95%CI: 1.2\u201312). Trace-back investigations identified kale producers from Sweden, Belgium, and Spain, but no particular grower was identified, and no food samples were available for microbiological analysis. Our investigation indicates that leafy greens such as kale may contain <jats:italic>Cryptosporidium<\/jats:italic> spp. and cause outbreaks and it is important to understand how the contamination occurs to prevent future outbreaks and apply adequate preventive measures.<\/jats:p>","DOI":"10.1017\/s0950268824001432","type":"journal-article","created":{"date-parts":[[2024,11,18]],"date-time":"2024-11-18T06:58:07Z","timestamp":1731913087000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":8,"title":["Outbreak of the novel <i>Cryptosporidium parvum<\/i> II\u03b3A11 linked to salad bars in Sweden, December 2023"],"prefix":"10.1017","volume":"152","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8684-0160","authenticated-orcid":false,"given":"Ioana","family":"Bujila","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Ohlson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anette","family":"Hansen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lady","family":"Agudelo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sharon","family":"K\u00fchlmann-Berenzon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ilias","family":"Galanis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ingela","family":"Hall","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ann-Mari","family":"Gustavsson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marianne","family":"Lebbad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mats","family":"Lindblad","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"R\u00f6nnberg","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moa","family":"Rehn","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2024,11,18]]},"reference":[{"key":"S0950268824001432_r15","doi-asserted-by":"publisher","DOI":"10.1186\/s13071-019-3348-4"},{"key":"S0950268824001432_r17","doi-asserted-by":"publisher","DOI":"10.1016\/j.vetpar.2014.11.009"},{"key":"S0950268824001432_r6","doi-asserted-by":"publisher","DOI":"10.3201\/eid2004.121415"},{"key":"S0950268824001432_r5","doi-asserted-by":"publisher","DOI":"10.1186\/s12889-017-4233-8"},{"key":"S0950268824001432_r12","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.41.6.2744-2747.2003"},{"key":"S0950268824001432_r1","doi-asserted-by":"publisher","DOI":"10.1016\/S1473-3099(14)70772-8"},{"key":"S0950268824001432_r4","doi-asserted-by":"publisher","DOI":"10.1186\/s12879-024-09049-x"},{"key":"S0950268824001432_r13","doi-asserted-by":"publisher","DOI":"10.1093\/molbev\/msy096"},{"key":"S0950268824001432_r9","unstructured":"[9] H\u00e4lsorapport - Folkh\u00e4lsomyndighetens webbpanel, 29 December 2023.
