Bonnie Rose, a microbiologist with the Food Safety and Inspection Services division of the USDA, develops laboratory-testing methods for food-borne diseases like E. coli and salmonella.

Rose’s work has centered on the development of laboratory testing methods for E. coli and salmonella. Her methodologies are now used worldwide as advanced detection practices for these food-borne pathogenic bacteria.

Last month, Rose, who grew up in Harrisonburg, was one of 12 recipients of the USDA’s 2006 Unsung Hero Award. According to the USDA, the Unsung Hero designation is meant to "identify those employees who have been unusually dedicated and efficient and [have a] positive attitude."

Rose, now living in Laurel, Md., has authored more than 90 scientific publications on food microbiology.
