The Epidemic You’ve Never Heard of
Alpha-gal syndrome (AGS), or mammalian meat allergy, is a tick-induced allergy to galactose-α-1,3-galactose. This sugar, commonly known as alpha-gal, is found in non-primate mammals and foods, medications, and other products with ingredients derived from mammals. Reactions, which can be life-threatening, may be immediate, as in the case of injected drugs, or delayed from 2 to 10 hours, as is typical after the consumption of mammal-derived foods.
In the U.S., the
lone star tick
is thought to be the primary vector of sensitization.
Have you been bitten by a tick?
Do you get sick in the middle of the night after eating red meat?
Do you have unexplained anaphylactic reactions, hives, GI issues, or arthritis?
You may have alpha-gal syndrome.

Diagnosis and Testing
Expert Scott Commins Explains Alpha-gal Syndrome
Fast facts about
“…in the southeastern United States, approximately 3% of the general population exhibits anaphylaxis after consumption of mammalian meat.”
“In certain geographic areas and in populations with high tick exposure, the level of sensitization can be 15-35% but this does not represent clinical AGS, which appears to occur in 1-8% of sensitized individuals.”
“In geographic areas where tick bites are common, AGS is likely under- recognized and under-diagnosed. We suggest testing for alpha-gal IgE in tick-endemic areas as part of the evaluation for cases of idiopathic anaphylaxis, recurrent urticaria and/or angioedema, as well as recurrent, episodic gastrointestinal cramping of unestablished cause.”
*most of the southeastern U.S. and other populations with high tick exposure, including areas of the Midwest and much of the eastern U.S.
