Dr. Deng’s research focus is microbial control on fresh produce during postharvest processing. For example, gene analysis of Escherichia coli O157:H7 linked to outbreaks of illness associated with fresh produce; and developing validation strategies for fresh-cut produce wash. Dr. Deng also co-leads the Sprout Safety Alliance, which develops a curriculum and training programs, and provides educational and technical assistance to the sprout industry.
