In May/June 2009 a CVM expert on residue chemistry, Dr. Tong Yan, worked with the Bureau of Veterinary Medicine, MOA and Elanco Animal Health experts to provide guidance on estimating residue levels of ractopamine in lung and other tissues. Based on this work in China, additional assessments are currently being carried out by the WHO/FAO Joint Expert Committee on Food Additives in order to make recommendations for Maximum Residue Limits in lung tissue.
In December 2006, one of CVM’s human food safety experts, Dr. Steve Yan, was sent to China to help USDA facilitate a negotiation involving the delisting by China of several U.S. pork producing plants, potentially restricting significant U.S. pork exports. The delegation was led by the Under-Secretary for Food Safety and the FAS Administrator. The delegation met with AQSIQ and other Chinese governmental agencies. The talks proved to be successful in permitting continued U.S. pork exports and provided a very positive beginning for the first U.S.-China Strategic and Economic Talks that were convened in Beijing during the following week.
In summary, all of this work by CVM with China’s technical experts and administrative officials has contributed to an atmosphere of collaboration and continuing trust covering many food safety matters, especially those related to the safety of veterinary drug residues in foods, including the potential risk of resistant microorganisms developing from the use of veterinary antimicrobials.
