Three pork producers had imports halted after the Canadian Food Inspection Agency (CFIA) informed Beijing it had uncovered fake health certificates being used in some meat products.
China has confirmed a batch contains residue of ractopamine, a drug which accelerates growth that is banned in China, Russia and the European Union. The batch reached Nanjing and came from Frigo Royal.
The Chinese Embassy said in a statement: “China has taken urgent preventive measures and requested the Canadian government to suspend the issuance of certificates for meat exported to China.
“We hope the Canadian side would attach great importance to this incident, complete the investigation as soon as possible and take effective measures to ensure the safety of food exported to China in a more responsible manner.”
Authorities have said they will open all containers sent from Canada.
Canadian Agriculture Minister Marie-Claude Bibeau said: “This incident is specific to export certificates to China. Export certificates to other countries are not affected.”
