Environmental Investigation of a Campylobacteriosis Outbreak Among Wedding Attendees - York County, Pennsylvania,
Abstract:
In early June 2025, approximately 80 persons attended a wedding at a venue in York County, Pennsylvania. Within 3 days, multiple attendees reported experiencing gastrointestinal illness. On June 23, the Pennsylvania Department of Health (PDOH) and the Pennsylvania Department of Agriculture (PDA) contacted CDC to request assistance after PDOH became aware of a laboratory-confirmed Campylobacter jejuni infection and reports of approximately 20 additional symptomatic attendees, with epidemiologic information implicating exposure to untreated spring water at the venue as a common exposure source. The focus of this report is on environmental inspection, testing, and identification of pathogens. This activity was reviewed by CDC, deemed not research, and conducted consistent with applicable federal law and CDC policy.
