I was wrong...

... in my first thoughts about the Spinach/E.Coli problem. My first thought when I first heard about it was "It's probably the organic stuff."

Indeed, I was supported in that theory by the picture in this article. The company is denying that its organic products are affected, although the FDA isn't ruling anything out.

So, at this point, nothing is really known. I'll be very interested in the final conclusions if anyone comes across them before I do.
