Meat from any kind of mammal — beef, lamb, pork, goat, and even whale and seal — can cause an allergic reaction. While we do not know the number of people in the U.S. affected by meat allergy, we do know that it is uncommon.
Unlike common food allergies to milk, egg, peanut, and wheat that present as immediate skin, respirtatory tract, and gastrointestinal sympotms, meat reactions are delayed for 4-6 hours. This delay often allows the preceding meal to be missed in the diagnostic detective work.
Ironically, a bite from the Lone Star tick can cause people to develop an allergy to red meat, including beef and pork. The Lone Star tick has been implicated in initiating the red meat allergy in the US and this tick is found predominantly in the Southeast from Texas, to Iowa, into New England.
A meat allergy can develop any time in life. If you are allergic to one type of meat, it is possible you also are allergic to other meats, as well as to poultry, such as chicken, turkey and duck.
