i keep resisting posting fda notices (like an erection aid that has been recalled because it *actually* has viagra in it) but here's one i couldn't resist - my emphasis added:
Harry & David Operations Corp., of Medford, Oregon, is voluntarily recalling approximately 5880 tubs of the Milk & Dark Chocolate, White Chocolate Macadamia because they may contain macadamia nuts not declared on the ingredient statement, and 4400 tubs of the Peanut Butter, Milk Chocolate, Macadamia Nut because they may contain macadamia nuts and peanuts not declared on the ingredient statement.
