While completing his master's degree in food engineering at the University of Missouri in 1993, the restaurant chain had an outbreak of Escherichia coli. He chose his degree because he wanted to protect food from pathogens, and that outbreak sealed his fate, so to speak.

More than 20 years later, the food industry remains vulnerable.
