Cases of red meat allergy linked to tick bites are increasing in Kansas and Missouri, health experts report. Known as alpha-gal syndrome, the condition can develop after a bite from a lone star tick. Symptoms—including hives, nausea, shortness of breath, and even anaphylactic shock—may appear two to six hours after consuming red meat or other mammal products such as cow’s milk or gelatin.

Experts say climate change is contributing to the rise, as warmer summers allow tick populations to grow in Kansas. The condition is likely underreported because reporting is not required by state or local health authorities, making it difficult to track the exact number of cases.

Missouri’s MU Extension is developing educational resources and conducting a survey to better understand the experiences of people with alpha-gal syndrome. Kansas residents are advised to take precautions against tick bites and seek medical guidance if symptoms occur.
