Recent research uncovers tick bite as the cause for a delayed allergic reaction to red meat

Quote:
Wolver, Sun and colleagues' analysis of three patient case studies sheds light on this reaction. It is thought to be caused by antibodies to a carbohydrate (alpha-gal) that are produced in a patient's blood in response to a tick bite, specifically the Lone Star tick. This carbohydrate substance is also present in meat. When an individual who has been bitten by a tick eats the meat, his or her immune system activates the release of histamine* in response to the presence of alpha-gal, which can cause hives and anaphylaxis. Significantly, meat-induced anaphylaxis is the first food-induced severe allergic reaction due to a carbohydrate rather than a protein. It is also the first time anaphylaxis has been noted to be delayed rather than occurring immediately after exposure.
