In September\/October 2022, we performed a cross-sectional study among HCW from 14 institutions in Northeastern Switzerland. HCWs reported risk factors for antimicrobial resistance (covering the last 12\u201324 months) and provided rectal swabs. Swabs were screened for ESBL-E, CPE, and VRE; whole-genome sequencing (WGS) was performed to assess the genetic relatedness. Logistic regression was used to identify occupational and non-occupational risk factors. Among approximately 22,500 employees, 1,209 participated (median age 46 years, 82% female). Prevalences of ESBL-E (\n                      <jats:italic>n<\/jats:italic>\n                      = 65) and CPE (\n                      <jats:italic>n<\/jats:italic>\n                      = 1) were 5.4% [95% confidence interval (CI) 4.2\u20136.8] and 0.1% (95% CI 0.0\u20130.5), respectively; no VREs were detected. In the multivariable analysis, non-European ethnicity [adjusted odds ratio (aOR) 7.0, 95% CI 1.4\u201327.3], travel to high-risk countries (aOR 4.9, 95% CI 2.5\u20139.3), systemic antibiotics (aOR 2.1, 95% CI 1.1\u20133.7), antibiotic eye drops (aOR 4.7, 95% CI 1.7\u201311.9), and monthly sushi consumption (aOR 2.4, 95% CI 1.4\u20134.3) were positively associated with ESBL-E colonization, whereas alcohol consumption (aOR 0.5 per glass\/week, 95% CI 0.3\u20130.9) was negatively associated with ESBL-E colonization. Occupational factors showed no association.
