When Fran Stump of Lusby first started breaking out into hives about the size of a silver dollar, accompanied by nausea and an upset stomach, about four to six hours after some meals, her husband thought it was cheese. Somebody else thought it was additives, while another believed salt to be the culprit.

But Stump, who had started a detailed food diary after her first allergic reaction in September 2011, narrowed down the common denominator: beef and pork, which she had previously eaten without a problem.

Stump?s reactions, of which she had four more during the course of about two years, became progressively more severe. During the fifth and final one, her heart raced and her blood pressure dropped.

Poultry and seafood can be tolerated, but many sufferers choose to avoid meat entirely.

Cases of the emergent allergy have been reported in Europe, Asia, Central America and Africa, but it is most prevalent ? and on the rise ? in parts of Australia and the United States where ticks are endemic and host populations are booming...
