Level III
unknown or higher risk profile = core information + results of analysis + safety rationale and supplemental data

4.1 Administrative Forms and Fees (Level I, II and III)

This section outlines the five administrative requirements for an application for registration.

4.5 Safety Rationale and Supplemental Data (Level III)

1. Hazard Assessment

Identification and characterization of potential adverse effects on human, animal and plant health, and the environment

2. Exposure Assessment

Predicts the extent and duration of the exposure

3. Risk Assessment and Mitigation Measures

The risk assessment is based on the hazard, and what is known about exposure Risk = Hazard x Exposure

A) Toxicological Risk Profile

Toxicological Hazard Characterization

The applicant is responsible to identify all potential hazards associated with each ingredient in the product, including:

  1. Human Health Hazards:

    Acute (oral, dermal, inhalation); Subchronic (oral); Irritation (ocular, dermal); carcinogenicity; reproductive and developmental toxicity; endocrine disruption

  2. Environmental Hazards:

    Aquatic hazard profile (toxicity to vertebrates, invertebrates, benthic organisms, and algae)

    To assist in this characterization, all fields in Appendix 4 (in the supporting Guide) must be completed for all ingredients. 

Toxicological Exposure Assessment

The applicant is responsible to provide the exposure assessment for all ingredients and potential contaminants. Factors to consider include:

  • Routes of exposure: direct (applicator/user) and indirect (bystander, groundwater, contaminated soil contact, and food/feed consumption)
  • Intended use patterns (e.g., agricultural field use vs potting mixes; ornamental plant species vs food crops)
  • Application rate and frequency of application
  • Protective measures, such as personal protective equipment, re-entry restrictions, and post-harvest intervals
  • Must consider worst case exposure scenarios/studies

All fields in Appendix 5 (in the supporting Guide) for all constituent materials for which a high hazard level has been identified (Appendix 4) must be completed.

Toxicological Risk Assessment

The applicant is responsible to provide estimates of risk by combining the hazard characterization with exposure assessment.

The risk estimates derived by the applicant are subject to review and validation by the Fertilizer Safety Section (FSS) and additional information/ test data may be required in order to refine the exposure and hazard assessments and/or further mitigative measures may be imposed to facilitate safe use of the product.

Risk = Hazard x Exposure

B) Microbial Risk Profile

Microbial Hazard Assessment

The applicant is responsible to identify all potential hazards associated with the microorganism, including:

  1. Human, Animal and Plant Health Hazards:
    • Toxin production potential
    • Pathogenicity profiles
    • Allergenicity / Sensitization potential
  2. Environmental Hazards:
    • Effects on target and non-target species
    • Resistance to adverse environmental conditions (e.g., cold tolerance)
    • Resistance to selectable traits (antibiotic, heavy metal resistance)
    • Invasiveness

To assist in this characterization, all fields in Appendix 6 (in the supporting Guide) must be completed.

Microbial Exposure Assessment

The applicant is responsible to provide the exposure assessment of the microorganism.  Factors to consider include:

  • Natural occurrence (e.g. geographical distribution, hosts)
  • Physiological properties (e.g. growth parameters - temp, pH)
  • Description of the life cycle, including potential for dispersal
  • Product use pattern, and expected routes of exposure (e.g. dermal, inhalation, ingestion)

To assist in the exposure assessment, applicants must complete all fields in Appendix 7 (in the supporting Guide).

Microbial Risk Assessment

The risk assessment conclusion is based on the hazard and exposure. The FSS will review and validate the risk estimates derived by the applicant and additional safety data may be required.

Considerations for classification of microbial hazard severity and exposure levels are summarized in Appendix 8 of the guide, for your information.

Where appropriate, any preventative risk mitigation measures may be required.

Example of a Precautionary Statement:

"This product may contain fungi and/or bacteria and may cause adverse effects in individuals who are allergic to certain microorganisms including moulds and otherwise immunocompromised  individuals. Avoid exposure through inhalation or open wounds and eyes. Wear standard protective clothing and equipment during product handling and storage. Use this product in well ventilated areas"

Surrogate Data

In cases where information or elements of it are not available for a given ingredient, information pertaining to a similar substance or microorganism may be submitted (surrogate data).

This requires a rationale demonstrating similarity between the substances of interest and its surrogate including all relevant characteristics (physical, chemical, or toxicological).

Surrogate data for microorganisms must be substantiated by a comparison of the organism under review and its surrogate with respect to pathogenicity, toxigenicity and its  behaviour in the environment (persistence, life cycle, invasiveness etc.)

List of Products Requiring a Safety Rationale and Supplemental Data (Level III assessment)

  • Polymeric soil stabilizers and wetting agents
  • Registerable supplement(s)
  • Nano-encapsulated fertilizers and nano-materials
  • Plant growth regulators (other than IBA)
  • Inoculant extenders sold with an inoculant
  • Viable microorganisms
  • Metabolites of organisms
  • Plant signalling compounds (e.g. LCOs, Hesperetin, Naringenin)
