Is there anything we can do to not get a foodborne illness?
Eh, there's not much you can do, proactively, aside from paying attention to food recalls (which is why you should always be checking Thrillist, daily!)
It's really not on the consumer here. It's not like you could -- or should -- be opening up your premade Trader Joe's wrap, washing the lettuce, and then placing it back in the wrap. But, for the highly vigilant among us, you can always opt to buy less pre-packaged produce -- or food items that contain them -- to help reduce your risk, especially the pre-sliced variety. But that might be a little bit of overkill. You are playing the odds, but your odds are still pretty good.
Just as E. coli in hamburgers spurred regulation changes in the '90s, we can only hope that this recent string of highly publicized outbreaks will draw increased attention to these outbreaks.
Because we do love our sliced produced. It's just so much easier than doing the slicing ourselves. Even at the risk of making a new, parasitic friend.
