As the mother of a child with food allergies, Heather Sapp was well-versed in reading labels and calling manufacturers to verify ingredients. For years, she kept her daughter’s diet free of the peanuts and tree nuts that could kill her.
But when a bite of lemon-ginger hummus three years ago sent Sapp herself into life-threatening anaphylactic shock, her dependence on labeling accuracy became more complicated. Testing determined that Sapp, now 43, had developed adult-onset allergies to chickpeas, sesame, and cilantro. More recently, Sapp, who lives in Phoenix, had an anaphylactic reaction to parsley.
