Researchers have discovered that a Lone Star tick bite can make some people react to the alpha-gal carbohydrate, a complex sugar found in red meat like beef and pork.
Understanding the Link Between Meat Allergies and Tick Bites
Alpha-gal syndrome isn’t listed on the CDC website as a tick-borne disease. Scott Commins MD, PhD, an associate professor of medicine and pediatrics at the University of North Carolina, says that makes sense, because this is more of an allergy than a disease. He is part of the team that first discovered that the Lone Star tick can cause a meat allergy. He did that while working at the University of Virginia with Thomas A.E. Platts-Mills, MD, the doctor who discovered alpha-gal was the cause of allergic reactions to a cancer drug.
a study published last week in Annals of Allergy, Asthma and Immunology reports the alpha-gal meat allergy was the most common known cause of anaphylaxis at the University of Tennessee Health Science Center between 2006 and 2016 — accounting for 33% of 218 cases reviewed.
Debendra Pattanaik, MD, lead author of the study and an associate professor of medicine at the University of Tennessee Health Science Center in Memphis, says an increase in the Lone Star tick population since 2006 is the likely cause of the jump in cases, as is a better understanding in the medical community that tick bites may cause the alpha-gal allergy.
“Our research clearly identified alpha-gal as the cause of anaphylaxis in the majority of cases where the cause was detected. Food allergies were the second leading cause, accounting for 24%,” Pattanaik says.
