Steve Ricke was raised on a dairy farm in south central Illinois. He received his B.S. and M.S. (ruminant nutrition) from the University of Illinois-Champaign-Urbana. and Ph.D. (double major-Bacteriology and Animal Science) from the University of Wisconsin-Madison. Dr. Ricke was a USDA-ARS postdoctorate in the Microbiology Department at North Carolina State University where he worked on the genetics of nitrogen fixation by the bacterium Azotobacter. In 1992 he joined Texas A&M University as an Assistant Professor in the Poultry Science Department and was a faculty member in the nutrition and Food Science and Technology interdisciplinary programs. In 2005, he became the first holder of the new Donald “Buddy” Wray Endowed Chair in Food Safety and Director of the Center for Food Safety at the University of Arkansas (UA) and faculty member of the Dept. of Food Science and Cellular and Molecular Graduate program until 2020. In October 2020 Dr. Ricke became of the Director of the Meat Science and Animal Biologics Discovery Program in the Animal and Dairy Sciences Department at the University of Wisconsin-Madison. He received the Poultry Sci. Association (PSA) Research Award in 1999, American Egg Board award in 2006, the PSA Evonik Award for Achievement in Poultry Science in 2019 and the National Chicken Council Broiler Research Award in 2020. He was honored as a Texas Agricultural Experiment Station Faculty Fellow in 2002 and the UA Division of Agriculture – John White Outstanding Research Award in 2012. He served as co-founder and former President of the Arkansas Association of Food Protection (AAFP). He was named an AAFP Fellow in 2015, a PSA Fellow in 2017, an International for Food Protection Fellow in 2019 and a University of Wisconsin College of Agricultural and Life Sciences Distinguished Alumni in 2019. He served as an American Society for Microbiology Distinguished Lecturer from 2015 to 2017. Dr. Ricke’s foodborne research projects have emphasized studies on the growth, survival and pathogenesis of foodborne pathogens in the gastrointestinal tract (GIT) and their interactions with the GIT microbiota. He is also exploring the interaction between different prebiotics, the GIT microbiota and host responses.
