A friend of mine headed to the Union Square Whole Foods recently for some meat. She was interested in getting grass-fed stuff, and I told her that I knew they had grass-fed lamb from New Zealand, but wasn't sure about the beef offerings. Later she reported back about her experience (after purchasing lamb steaks and some ground beef). She says the butcher kept insisting that the beef was grass-fed, saying "See, it says, 'organic,' which means 'grass-fed.'"
Note to Whole Foods butchers: Organic does not mean grass-fed. Some organic may be grass-fed, some grass-fed beef may be organic. But it's not the same thing. It's confusing enough to figure out what's going on with our food supply. You'd expect someone who's selling it to you to at least have an understanding about what the labels mean.
