On 13 June 1999, the Vegan Society Council reviewed the Society's policy on Genetically Modified Organisms (GMOs). The following GM policy was adopted:
"In keeping with its vegan ethic, the Vegan Society is totally against the use of animal genes or animal substances in the development and production of GMOs. The Vegan Society believes that all foods that contain, may contain, or have involved GMOs should be clearly labelled.
In addition any product must also meet the Society's Criteria for Vegan Food. Products carrying the Society's trademark can contain GMOs, but must be clearly labelled and comply with the definition above."
