Dr. Jaroni is an associate professor in our department. Her area of expertise includes pre- and post-harvest food microbiology, lactic acid bacteria for use as competitive exclusion, and foodborne pathogens particularly E. coli O157:H7; Salmonella spp. and non O157 STECs. Her research projects include:

- Reduction of Escherichia coli O157:H7 in Small-Scale Cow/Calf Operations Using Best Management Practices

- Improving the Safety and Quality of Field Grown Organic Leafy Greens: Assessment of Good Agricultural/Production Practices Along the Farm-to-Fork Continuum

-Assessing the Food and Environmental Safety and Economic Feasibility of Mobile Slaughter Units for Pasture Poultry Growers in the Southeast

-Effectiveness of plant-derived antimicrobials against food pathogens in meat and fresh produce

About Dr. Jaroni

Jaroni was born and raised in the city of Indore in India where she received her first bachelor’s degree in chemistry and biology. Her passion for teaching prompted her to get a second bachelor’s degree in education. The desire to get a higher education brought her to the University of Nebraska-Lincoln, or UNL, to pursue an M.S. in animal science with a focus in non-ruminant nutrition. At UNL, she learned about the discipline of food science and decided to pursue a doctoral degree with specialization in food microbiology. Her dissertation focused on the control of E. coli O157:H7 in live cattle, and that work produced a patented Direct-Fed- Microbial (DFM, Bovamine™) for beef cattle.

Following graduation, she joined the “E. coli team” at UNL, under the mentorship of Terry Klopfenstein and Rodney Moxley. This position was a continuation of her Ph.D. project where she tested the DFM as a dietary supplement in live cattle. In 2002, Jaroni joined the USDAMARC in Clay Center, Nebraska as a postdoc, followed by a second postdoc at UNL. She then joined the faculty of Southern University, or SU, Agricultural Research and Extension Center in Baton Rouge, Louisiana, where she continued to conduct food safety research in food animals. After five years at SU, she joined Oklahoma State University in 2012 as an assistant professor with an 80% research and 20% teaching appointment. In 2014, she also became part of the Robert M. Kerr Food and Agricultural Products Center. Recently, Jaroni was promoted to associate professor.

Jaroni is passionate about food safety research and teaching. Her current research focuses on strategies to reduce foodborne pathogens within the food production chain. She has been very successful in obtaining both extramural and intramural funds. Research in her lab has been supported by several of these funded projects, totaling more than $3 million. Jaroni has 147 publications stemming from her research, with 37 peer-reviewed journal articles, 50 abstracts, 4 book chapters, 6 articles in magazines and newsletters and 50 proceedings and technical reports. She has 13 invited presentations and more than 50 research presentations at various national and international professional conferences.

Jaroni has been involved in the education of students, consumers and industry professionals. She developed three new courses at OSU in the area of food microbiology/food safety to be offered to undergraduate and graduate students in the food science and animal science programs. She also introduced the Pre-Harvest Food Safety course, which is one of the few courses of its kind being offered in the country. Jaroni also teaches Advanced Food Microbiology and Foodborne Toxins and Allergens for undergraduate and graduate students. In addition to teaching, she serves as an academic advisor for 18 undergraduate students, as a research mentor for three undergraduate research scholars and as a supervisor for 15 undergraduate research assistants in the food microbiology lab.
