Enteric Outbreak Seminar Series – Save the Date! 

May 8, 2026

The Public Health Agency of Canada is pleased to announce the next session of the Enteric Outbreak Seminar Series (EOSS). EOSS is brought to you by the Centre for Food-borne, Environmental and Zoonotic Infectious Diseases’ Outbreak Management Division. The Outbreak Management Division detects, assesses, and responds to multi-jurisdictional outbreaks of enteric illnesses in Canada and provides expertise, support, and training to public health authorities investigating enteric illness outbreaks.

EOSS aims to increase knowledge and awareness of enteric illness outbreak investigations in Canada, including novel approaches, research, special projects, and upcoming or recent changes in policy or practice.

The next seminar will take place on June 10th, 2025 from 14:00-15:00 EST. Live audio interpretation (French) and live captioning (French and English) will be available.

Findings from the freezer: A multi-jurisdictional outbreak of E. coli O26:H11 linked to pizza pops

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.
