A person bitten by a Lone star tick can develop alpha-gal syndrome, resulting in a severe red meat allergy. There is a sugar, known as alpha-gal, found in the saliva of Lone star ticks. This sugar is also found in many foods, including beef, pork, lamb, venison, and dairy products. Therefore, the same way people can produce antibodies against peanuts, some people can produce antibodies against this sugar found in the meat after being bitten by a Lone star tick. Alpha-gal syndrome can be incredibly dangerous, as some people may develop anaphylactic shock.
