DO NOT eat hummus or walnuts before reading about these ongoing food recalls — also avoid the ground beef. I know, I know, I always say that — but this time (in addition to many other good reasons!) it’s an e. coli contamination thing. The week’s food safety issues aren’t just bothering 2-legged diners: if you have canine friends, beware the toxic jerky! So, yes, the week’s news does feature some ickiness. But don’t be scared — there’s also some nifty GMO news, plus research on Paleo diets, cheap food, and obesity. Holy guacamole, but there’s much to report this week!
