A Deadly E. Coli Outbreak in Walkerton, Ont., Changed Everything 25 Years Ago
- Canada's worst E. Coli O157 outbreak began on May 17, 2000, in Walkerton, Ontario, sickening about 2,300 people and causing seven deaths.
- The outbreak occurred after heavy rains from May 8 to 12 washed cattle manure into a well managed by brothers Stan and Frank Koebel, who delayed reporting contamination.
- A warning to boil the water was announced on May 21, but this came after many people had already fallen ill, sparking nationwide anger and leading to a nearly two-year-long public inquiry overseen by Justice Dennis O'Connor.
- The inquiry produced a set of recommendations that became the foundation for Ontario’s key legislation on water safety, with expert Theresa McClenaghan noting that the investigation was thorough and comprehensive.
- Despite reforms and rigorous testing, access to safe drinking water remains a serious issue, especially in First Nations communities, with reports showing 35% of private well samples contaminated.
