Indeed they are. Until recently, international standards in terms of listeria control didn't exist. But I am pleased to say that this summer the Codex Alimentarius Commission adopted standards for listeria control, and those standards are directly aligned with the standards established by Health Canada in terms of foods that both can and cannot support growth of listeria monocytogenes. So Canada's standards are directly aligned with the current international standards.
