The General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) said tests -- conducted by it and the US Food and Drug Administration -- had not confirmed any connection and had not detected any poisonous or hazardous ingredients in the snacks, despite allegations that they were the cause of widespread illness and death in US pets.
The statement came after US pet speciality retailer Petco announced earlier this month that it was pulling all pet treats made in China from its 1,300 stores because of concerns they had caused sickness in thousands of pets and killed more than 1,000 dogs in the US since 2007.
Phoenix-based PetSmart Inc also plans to remove the treats from its stores by March.
China will closely follow events and hopes the parties concerned can remain objective and rational, the AQSIQ said in a statement on its website, state-run Xinhua news agency reported.
