Repellents applied to skin have limitations, but permethrin-treated field clothes can be worn several times and still reduce tick exposure.Reduce the number of ticks brought into the house by putting field clothes in a clothes dryer on high heat for 30 minutes.To prevent the red meat allergy, avoid bites by lone star ticks. In some individuals, the severity of the allergy diminishes over time (sometimes several years) if there are no further exposures to lone star tick bites and saliva. To prevent allergic reactions in the future, a person diagnosed with red meat allergy must stop eating red meat. Mild symptoms can be treated with antihistamines while severe allergic reactions require emergency medical attention and epinephrine. Symptoms may include itching, hives, vomiting, diarrhea, swelling of the tongue and throat, difficulty breathing, dizziness and gastrointestinal pain. Symptoms of red meat allergy can occur 2 to 8 hours after a person eats red meat and can range from mild to severe to life-threatening anaphylaxis. Then, when people with alpha-gal in their body eat red meat, the human immune system has a strong response. Alpha-gal is also in the saliva of lone star ticks and enters the human body by a tick bite. The source of this allergy is a sugar molecule, alpha-gal (galactose-alpha-1,3-galactose) that is found in meat and other products from non-primate mammals, including beef, pork, venison, and rabbit. The red meat allergy, also called alpha-gal syndrome, is a delayed allergic reaction to red meat. It is the second most frequently reported tick and its bite may trigger a potentially life-threatening allergic reaction in humans after they eat red meat. Lone star ticks are widely distributed across the East, South and Central United States, extending across the southeastern portion of Nebraska (see figures at the end of the article). There are three tick species established in Nebraska that carry and spread diseases to humans and animals, including the lone star tick. ![]() ![]() Ticks may be active all year long if temperatures outside are above freezing, but May and June are the months when people pick up the most ticks. ![]() Spring is an appropriate time for tick education.
