Priority C (lower hazard) micro-organisms on the Domestic Substances List
Priority C (lower hazard) micro-organism strains on the Domestic Substances List (DSL) were identified for expedited assessment based on their meeting the criteria for lower potential to cause harm to human health or the environment as described in Prioritization of Micro-organisms on the Domestic Substances List. Evidence of significant hazard during the screening assessment would result in the micro-organism strain being removed from Priority C and reprioritized for further assessment. To learn more, view the Assessment Approach for Priority C (Lower Hazard) Micro-Organisms on the Domestic Substances List. Information on all micro-organism assessments is also available.
