The source of the largest outbreak of E. coli O157:H7 in more than a decade is still unsolved. It caused tremendous human suffering, many lawsuits, 45% drop in consumption of romaine lettuce. It also resulted in losses to growers, retailers, and restaurants.

Perhaps the effort should focus on the reduction of the chances of a new one happening.
