More salad consumption leading to more health problems?

It's interesting to hear that an increase in healthy (or unhealthy, I suppose) salad consumption around the world is increasing the risk of disease and illness, but that is what U.S. scientists are saying.

The law of averages takes over here -- the more people consume a certain food type (which could have E.-coli or other bacterial problems), the more incidents of sickness will result.

On one hand, it's great to see more folks around the world eating vegetables and salads as opposed to more unhealthy food products or items. But, if the safety of those vegetables is of concern, there's going to be more possible problems. Are you going to stop eating salads. I won't.
