Interacting with college and graduate students majoring in agriculture

In 2009 and 2011 CVM visited one of the four key MOA laboratories performing research on animal drug residues in China. The laboratory located in Wuhan conducts residue depletion and other food safety studies to support drug applications for approval by IVDC. The laboratory is directed by Dr. Yuan Zhonghui, Chairman of the Department of Veterinary Basic Medicine, Central China (Huazhong) Agricultural University in Wuhan, Hubei Province. Professor Yuan is the principal scientist who regularly attends the CCRVDF as part of the Chinese delegation. He has designed and carried out studies of ractopamine residues in edible tissues that are consumed in China. During these visits CVM experts also presented workshops for Professor Yuan’s students and faculty to share information about programs directed toward harmonizing veterinary drug residue safety standards and antimicrobial resistance controls. In one such occasion, Dr. Steven Vaughn made a presentation on ractopamine and described CVM’s technical evaluation of this drug, explained the basis for some of the differing opinions within the CCRVDF members about the safety of residues of this drug in food, and emphasized the need to have a risk based approach to resolve these differences. All the presentations made to the students were well received and triggered many questions from the audience.
