Red Meat Allergy Caused By Lone Star Tick Bites Increasingly Prevalent In U.S.

Over 110,000 Americans have developed the allergy, known as alpha-gal syndrome, since 2010.
Up to 450,000 people may actually be affected, but many cases are undiagnosed.
The allergy is triggered when the Lone Star tick's saliva containing alpha-gal enters the bloodstream from a bite.
Symptoms range from hives and nausea to potentially life-threatening anaphylaxis.
There is currently no cure, only symptom management by avoiding trigger foods.
