Pathogen Safety Data Sheets (PSDSs) - MSDS data for micro-organisms - are technical documents that describe the hazardous properties of a human pathogen and recommendations for work involving these agents in a laboratory setting. These documents have been produced by the Public Health Agency of Canada as educational and informational resources for laboratory personnel working with these infectious substances. Please note that work involving pathogens in Canada may require compliance with International, National, and Provincial laws and guidelines.
