Extension Associate Professor, Food Safety Specialist

Omar is a lead instructor of HACCP (Hazard Analysis and Critical Control Points), FSMA (Food Safety Modernization Act) Preventive Control for Human Food, and Sprout Safety Alliance training. He is also a Certified HACCP Auditor (American Society for Quality) and has taught food safety, bioinformatics, biostatistics, microbial risk assessment and management, and introductory HACCP classes for more than 15 years. Omar has delivered numerous international presentations and short training courses on food safety in Argentina, Bangladesh, Brazil, Canada, Chile, China, Colombia, India, Mexico and Thailand.

Omar's research expertise is the identification, typing and control of foodborne pathogens, with emphasis on Campylobacter spp. Omar is also editor-in-chief of the new journal Microbial Risk Analysis, published by Elsevier; and affiliate associate professor at the Institute of Microbiology, Universidad Austral, Valdivia, Chile.

Omar has worked for GMA (ex National Food Processors Association), Neogen Corporation, Auburn University (associate professor, Department of Poultry Science), Alabama State University (associate professor, Ph.D. Program in Microbiology), and IEH Laboratories and Consulting Group.
