Here is an interesting article

Here's the thing about Chipotle. Its shares have literally been cut in half since it had a series of foodborne illness crises at the end of last year. The thing about it is that -- and I've written about this on Fool.com regularly over the past few months -- every other major food company, for the most part, in the United States has been through a similar experience, in terms of food-borne illness crises, seeing their stock fall, and then gone on to produce large gains. Whether that's Jack in the Box, McDonald's, Yum! Brands-- which owns KFC, Pizza Hut and Taco Bell.
Gaby Lapera: Can I ask you a question?
Maxfield: Of course.
Lapera: Have other brands had as a prolonged time period with foodborne illness news?
Maxfield: Really good point. There are some unique characteristics about Chipotle's foodborne illness situation. The first is that, like McDonald's -- its big
E. coli scandal was I think in 1993, so that was pre-internet so you didn't have that proliferation of information the same way that it happens now online. You didn't have that. However, while Chipotle seems like it's gone on for a long time, I think that what you really want to look at is the severity of the crisis itself. In that regard, Chipotle's was actually not very severe. Let me give you an example. Jack in the Box dealt with an
E. coli situation, I can't remember exactly when that was. It was a couple of decades ago. Something like four people died from it."
