Firms deny responsibility for poison pet food

SHANGHAI: The top quality control agency rejected a United States claim yesterday that contaminated pet food ingredients came from China.

A release from the General Administration of Quality Supervision, Inspection and Quarantine said China has never exported pet food ingredients made of wheat or wheat bran to the United States or Canada and that the country has nothing to do with the pet food poisoning incidents.

No exact number of pet deaths has been given but some reports put the number at hundreds, if not thousands. The chemical aminopterin was found in the food.
