The provincial government in Ontario, Canada, is considering steps to thwart the growth of legionella bacteria. The province saw an increase in Legionnaires’ disease cases within the past year, with one outbreak being associated with ten confirmed cases and one potential death. The Simcoe Muskoka District Health Unit is encouraging the province to establish a registry of cooling towers and to require cooling tower sites to establish risk-management plans, a common source of legionella bacteria growth. The health board believes the registry will allow it to save time and resources identifying cooling tower sites, so it can more quickly respond to potential outbreaks.
