32 cases is basically nothing. That they came from 11 different states tells me that any bacteria (if indeed there was any) is completely random and not from a single source, nor is a source itself contaminated. When you walk it through the ground to plate odyssey, it's unlikely that the romaine was the cause of any illness. And if it were, it would have to be individually tainted at the purchase point.
I'm always interested in these warnings over something statistically insignificant. I hold with romaine growers association not paying their political protection money, and now they're being punished.
But a word about fresh produce:
Think about all the grubby grocery store shoppers who handle the fruits and vegetables sitting out in bins. They have colds, they don't wash their hands after going to the bathroom, they pick their nose. I rarely buy loose produce, and when I do I wash the (literal) chit out of it. I won't even go near loose rolls or donuts that are accessible to the public's goober fingers. I'll still go to a salad bar or buffet, but only if it's super clean and well-monitored and people aren't letting their dumb kids stick their booger fingers in the bins.
