In November 2025, the Public Health Agency of Canada began investigating a new multi-jurisdictional cluster of Shiga toxin-producing E. coli (STEC) O26:H11. Through case re-interviews and the analysis of invoices and purchase records, investigators identified the source: frozen pizza pops. This seminar will provide an overview of the collaborative outbreak investigation, including sampling results and laboratory challenges associated with isolating STEC in foods such as pizza pops.
