Chemical Analysis of Non-Antimicrobial Veterinary Drug Residues in Food

Provides a single-source reference for readers interested in the development of analytical methods for analyzing non-antimicrobial veterinary drug residues in food

• Provides a comprehensive set of information in the area of consumer food safety and international trade
• Covers general issues related to analytical quality control and quality assurance, measurement uncertainty, screening and confirmatory methods
• Details many techniques including nanotechnology and aptamer based assays covering current and potential applications for non-antimicrobial veterinary drugs
• Provides guidance for analysis of banned drugs including natural and synthetic steroids, Resorcylic acid lactones, and Beta-agonists

Jack F. Kay works in the UK Department for Environment, Food and Rural Affairs. He has actively participated in the Codex Committee on Residues of Veterinary Drugs in Food for more than ten years.

James D. MacNeil retired as head of the Centre for Veterinary Drug Residues of the Canadian Food Inspection Agency in 2007. He is the former scientific editor for "Drugs, Cosmetics, and Forensics" of the Journal of AOAC International.

Jian Wang is currently a research scientist leading a research and development unit for the Canadian Food Inspection Agency in Calgary, Alberta. He has written over thirty publications for various journals and books.
