Darin Detwiler and I conducted this interview on Thursday. Detwiler is the senior policy coordinator for Stop Foodborne Illness and an instructor on regulatory affairs and food industries at Northeastern University. As I do, he has a deeply personal motivation to be in his line of work: His son was one of four young people who died in the 1993 E. coli outbreak at Jack in the Box restaurants in the Northwest. He tells that heartbreaking story in the interview, while also sharing vital information of use to anyone who eats.
