Joe Boison
Joe Boison, Ph.D., Senior Research Scientist (retired)
Canadian Food Inspection Agency, Saskatoon, Saskatchewan, Canada

Dr. Boison retired after 31 years of service from the Canadian Food Inspection Agency (CFIA) in early 2018 as a Senior Research Scientist, and holds two Adjunct Professor Faculty positions; one in the Chemistry Department and the other in the Department of Veterinary Biomedical Sciences at the University of Saskatchewan. In 2003, he was appointed a Fellow of the World Innovation Foundation (FWIF), was awarded the CFIA President’s National Award for Leadership Excellence in 2010 and in 2012, he was appointed a Fellow of the AOAC International.

Dr. Boison’s research activities in the Canadian Federal Government were centred on the development and validation of sensitive analytical methods for the pharmacokinetic and pharmacodynamic studies of veterinary drugs in food animals, the development and validation of hyphenated and tandem mass spectrometric methods for regulatory monitoring of the use of veterinary drugs in foods of animal origin to facilitate international trade and the use of the results from those initiatives by risk assessors to inform regulatory decisions to protect human and animal health and ensure food safety.  Dr. Boison was the subject matter expert for the Canadian Delegation to the Codex Committee on Residues of Veterinary Drugs in Foods (CCRVDF), a member of the Joint WHO/FAO Expert Committee on Food Additives (JECFA) and travelled extensively auditing and inspecting meat and poultry slaughter establishments and laboratory facilities of Canada’s trading partners. 

Dr. Boison has provided voluntary services to the AOAC since 1991 when he first accepted an appointment as an Expert Reviewer for Rapid Test Kits at the inception of AOAC Research Institute (AOACRI). He has since held positions of General Referee/Process Expert, Topic Advisor, Study Director, Expert Reviewer, Scientific Editor and member of the AOAC RI Board of Directors. He received the 2011 AOAC Process Expert General Referee Award and was awarded AOAC International’s highest scientific award, the Harvey W. Wiley Award for Research Excellence in 2015.

In 2007, Boison was appointed Section Editor for Veterinary Drug Residues for the Journal of AOAC International. Since accepting an appointment as an Expert Reviewer for veterinary drugs in 2007, Boison has served on and chaired several Expert Review Panels (ERPs) and provided scientific leadership directing/chairing the ERP meetings that have resulted in two methods for Official Method Final Action Status and 3 methods for Official Method First Action Status. Dr. Boison is currently co-chairing an AOAC International initiative for targeted testing procedures and methods in food authenticity and is the Chair-Elect for the AOACI Official Methods Board (OMB).
