Professor Victoria O. Adetunji Biography                                                                                                                                       Victoria O. Adetunji, is a professor of food safety, food microbiology and Public Health, with a demonstrated history of working in the research and education industry.  Victoria's main research interests are bacterial zoonotic food-borne pathogens of animal origin in food processing and environments (Pathogens under study include: Escherichia coli O157:H7 and other serotypes of enterohemorrhagic E. coli, S. aureus, Salmonella spp., Listeria monocytogenes and Campylobacter jejuni). She has strong professional skills for surveillance of bacterial pathogens, Polymerase Chain Reaction (PCR), Epidemiology, Microbial pathogenicity, control of pathogens and their biofilms in food processing environment, Research Design, and Program Evaluation. She is also interested in antimicrobial resistance and molecular investigation of virulence markers in zoonotic agents. She has experience in the design, development and application of   Food Safety/food quality control and Hazard Analysis Critical Control Point Systems (HACCPs) among local food processors, in particular in the milk and meat product’s value chains. She in addition does research for improved production and preservation of various African fermented and convenience foods of animal origin. Victoria in her role also contributes to the development of the veterinary public health curriculum. She is a Fellow of the College of Veterinary Surgeons Nigeria (FCVSN), member, American Society for Microbiology (AMS), member, the International Association for Food Protection (IAFP), member, International Food Safety and Quality Network (IFSQN) and Organization for Women in Science for the Developing World (OWSD). She is also an alumnus of the Fulbright Scholarship and Faculty for the Feature fellowship of the Schlumberger foundation.
