We’ve come a long way from those scary old days of duct tape in every room, judging by the reaction to the media-induced killer-tomatoes frenzy. CNN’s poll the other day showed respondents were about equally split on giving up the salmonella balls in wake of the news that our bureaucrats have let us down once  again. This story has yet to unfold completely, but what’s fascinating me is how a whole food group was condemned when increasingly it looks as if the problem was what it so often is: One “restaurant” chain. We need a new Agatha Christie to write food who-dun-its. Was it the tomato or the egg, or the spinach or the cantaloupe? But that series wouldn’t last long. The culprit would always be greed. Enjoy your 99-cent burger while you can.
