Leafy greens—including cut lettuces and spinach—have been responsible for several outbreaks of disease and product recalls in recent years. One of the biggest scares was the 2006 E. coli outbreak that was eventually linked to bagged spinach that sickened 199 people and was responsible for three deaths. There are many ways that bacteria like E. coli or salmonella can infect produce—from infected animal feces that infiltrate the water or soil or from handling procedures during the picking or packaging. In most situations, washing the produce will not wash away the risk.
