Priority B (medium hazard) micro-organisms on the Domestic Substances List

Priority B (medium hazard) micro-organism strains on the Domestic Substances List (DSL) were given a medium priority for assessment because while they are not specifically identified as pathogens, the Government of Canada identified evidence in the scientific literature that indicates they may have the potential to cause harm to human health or the environment. More information about the prioritization of micro-organisms on the Domestic Substances List is available. Information on all micro-organism assessments is also available. More information here
