NC red meat allergy cases are rising due to tick bites. Here's what to know
North Carolina is seeing more cases of alpha-gal syndrome, a red meat allergy triggered by lone star tick bites. A prominent researcher points to growing tick populations and warmer weather as factors driving the increase.
FULL STORY: North Carolina is seeing a rise in anaphylactic red meat allergies. Why?
Here are key takeaways:
- Alpha-gal syndrome causes allergic reactions to red meat ranging from anaphylaxis to gastrointestinal distress. The CDC confirmed more than 100,000 cases between 2010 and 2022, though actual numbers could reach 450,000.
- Dr. Scott Commins, a UNC Chapel Hill professor researching the syndrome, said his clinic now sees about 15 new patients a week, up from two to four a week 15 years ago.
- Fattier red meats like sausage, hamburgers and hot dogs tend to cause more severe reactions than leaner options like venison, Commins said.
- The allergy is not necessarily permanent. If patients avoid further tick bites, most return to their previous diet within three to five years.
- ER visits related to tick bites in 2026 are the highest since 2017, the CDC reported in April. Warmer winters and humid conditions are helping tick populations expand.
