NIAID scientists link cases of unexplained anaphylaxis to red meat allergy

(NIH/National Institute of Allergy and Infectious Diseases) While rare, some people experience recurrent episodes of anaphylaxis -- a life-threatening allergic reaction -- for which the triggers are never identified. Recently, researchers at NIAID found that some patients' seemingly inexplicable anaphylaxis was actually caused by an uncommon allergy to a molecule found naturally in red meat. They note that the allergy, which is linked to a history of a specific type of tick bite, may be difficult for patients and health care teams to identify.
