Lead poisoning in Ontario is rare, and often missed by clinicians due to typically non-specific symptoms. Lead exposure from Ayurveda and other traditional medicines is also under recognized. In this presentation, the audience will learn about the clinical, environmental and public health aspects of lead poisoning, through the lens of a multi-sectoral and multi-jurisdictional investigation. Speakers from Health Canada, Toronto Public Health (TPH), and Public Health Ontario (PHO) will discuss their roles in investigating a recent case of lead poisoning from use of contaminated Ayurvedic medicines.
