Someone posted a topic regarding bagged salads several weeks ago over on YT and since then, I've stopped purchasing them. Here's a link to a story off CNN where e.coli has been linked to bagged spinich in several states with one death because of it. If you purchase the bag salads like I used to, you may want to rethink that. I now buy the full head of lettuce or whatever greens I'm using with my salad.
