GMO/GMM classification and Risk Assessment

GMMs may be classified as Class 1, Class 2, Class 3 or Class 4, based on the risk the GMM poses to human health and the environment as determined by a Risk Assessment.

Performance of a risk assessment will identify:

  • the risks associated with the GMM; and,
  • the level of containment required to control that risk.

This in turn will determine the Class


Level of risk the GMM presents

Containment level required to control the risk

Class 1

No or negligible risk

Containment level 1

Class 2

Low risk

Containment level 2

Class 3

Moderate risk

Containment level 3

Class 4

High risk

Containment level 4


A risk assessment must also be performed in respect of GMO activities

It is responsibility of the user to carry out an assessment of the potential risks to human health and the environment and to ensure that all appropriate measures are taken to avoid adverse effects on human health or the environment.
