Expert Background

Dr. Willis Fedio is the Director of New Mexico State University's Food Safety Laboratory (FSL). He leads a group of scientists, graduate students and undergraduate students in the development and evaluation of rapid methods for the detection of pathogenic bacteria including E. coli O157:H7 and Salmonella spp. in produce and other foods. The FSL research group is involved in research on the microbiological safety of chile peppers, including development and evaluation of methods for detecting salmonellae in dried red chile peppers, flame roasting for inactivation of Salmonella spp. in green chile peppers, and methods for washing green chile peppers to minimize microbial levels in frozen peppers. FSL researchers also support the New Mexico food processing industry by providing technical support and process validation for acidified foods such as canned chile products.

The Food Safety Laboratory is a member of the Food Emergency Response Network, an organization which integrates the nation's food-testing laboratories at the local, state, and federal levels into a network that is able to respond to emergencies involving biological, chemical, or radiological contamination of food.
