Certification of the absence of contagious diseases in human ashes after flame-based cremation

This certification is based on the Québec legislation regarding the flame-based cremation process and the following elements:

  • The combustion process eliminates all organs and tissue;
  • The ashes contain only bone residues and non-organic particles;
  • The public health bodies, such as the World Health Organization and the American Centers for Disease Control and Prevention, consider that the temperatures reached during flame-based cremation deactivate and destroy all infectious agents, including prions.
