Priority A (higher hazard) micro-organisms on the Domestic Substances List

Priority A (higher hazard) micro-organism strains on the Domestic Substances List (DSL) were given a high priority for assessment because the Government of Canada considered them human, plant or animal pathogens (in the case of microbial consortia) or because their hazard level is uncertain. More information about the Prioritization of Micro-organism on the Domestic Substances List is available. Information on all micro-organism assessments is also available.

Applying the Significant New Activity provisions

Potential uses of concern for strains in Priority A are addressed through the application of the Significant New Activity (SNAc) provisions. View the complete list of Significant New Activity publications under the Canadian Environmental Protection Act, 1999. For guidance on submitting information required as part of a Significant New Activity Notification (SNAN), please see the new substances: guidelines for organisms.

Table 2 note 1

The Bacillus subtilis strain was subsequently added to the Bacillus cereusscreening assessment after its draft publication. The addition of this strain does not change any of the assessment outcomes.
