To the Editor: A 5-year-old girl with known peanut allergy presented with an acute allergic reaction after ingesting “nut-free” butter containing sunflower seeds (85%), sugar, emulsifier and antioxidant. The label on this product stated that it was processed in a peanut-free facility, and that each batch was tested for traces of nuts and peanut protein.
