Title: Tick Saliva Sugar Linked to Mysterious Meat Allergy, Affecting Hundreds of Thousands of Americans

A potentially life-threatening meat allergy, known as alpha-gal syndrome, affecting approximately 450,000 Americans has been linked to sugar found in the saliva of ticks. Researchers have discovered that the sugar alpha-gal (galactose-alpha-1,3-galactose) present in meat and dairy products is also present in the saliva of Amblyomma americanum ticks.
Dr. Scott Commins, an expert in allergy and immunology at the University of North Carolina School of Medicine, suggests that the enzyme in the saliva of these ticks may lead to the production of alpha-gal. When an individual is bitten by an Amblyomma americanum tick, the alpha-gal sugar enters the skin, triggering an immune response.
Unlike most food allergies that cause immediate reactions, alpha-gal allergy takes four to six hours to manifest, making it difficult to identify the specific trigger. Symptoms include hives, shortness of breath, and anaphylactic shock, which can be life-threatening if not treated promptly.
Shockingly, alpha-gal syndrome remains relatively unknown among healthcare professionals in the United States. A survey conducted by the Centers for Disease Control and Prevention (CDC) revealed that 42 percent of the 1,500 doctors and nurses surveyed had never heard of the syndrome, while 35 percent were unsure about diagnosing or treating the condition appropriately.
Until recently, the exact prevalence of alpha-gal syndrome in the U.S. was unknown. However, CDC epidemiologists analyzed test results from a major alpha-gal testing laboratory between 2017 and 2022, revealing approximately 90,000 positive cases out of nearly 300,000 tests. Taking into account previous research findings, experts estimate that there have been approximately 110,000 cases of alpha-gal syndrome in the U.S. between 2010 and 2022.
The lack of awareness among healthcare professionals has likely resulted in many cases going undiagnosed. The researchers estimate that between 20 and 78 percent of cases have been overlooked, meaning that there could be between 96,000 and 450,000 undiagnosed cases of alpha-gal syndrome in the U.S. since 2010.
Dr. Commins emphasizes the magnitude of the issue, stating, “If our estimate of about 450,000 cases is even remotely accurate, we have the ninth most common food allergy in the country.”
Amblyomma americanum ticks are primarily found in the southeastern United States, and most cases of alpha-gal syndrome have been reported in this region. However, cases have also been observed in other parts of the world, including Europe, Australia, Asia, South Africa, and South and Central America.
Raising awareness among medical professionals and the general public about alpha-gal syndrome is crucial for timely diagnosis and treatment. Individuals who have experienced unexplained allergic reactions after consuming meat should consult with their healthcare providers to rule out the possibility of alpha-gal syndrome.
Efforts are underway to educate healthcare professionals and improve diagnosis rates to ensure that those with alpha-gal syndrome receive appropriate care. As research continues, it is hoped that greater understanding and awareness of this relatively unknown food allergy will lead to better management and prevention strategies for those affected.]
