Because it somehow is inherently spinach that is the e. coli problem, right? Erm . . .
This is a camera phone pick from Philbrick's Fresh Market in Portsmouth - all the bagged salad was labeled like this, even though the USDA has given the all clear. [Philbrick's actually does a decent job carrying locally produced goods - today I found tortillas from Brentwood, NH and yogurt from Exeter, NH! They don't do a great job labeling these products as local, or highlighting them. They also don't do a great job buying or selling local produce.]
