A tick bite can make you allergic to red meat
The bugs harbor a sugar that humans don’t have, called alpha-gal. The sugar is also is found in red meat — beef, pork, venison, rabbit — and even some dairy products. It’s usually fine when people encounter it through food that gets digested. But a tick bite triggers an immune system response, and in that high-alert state, the body perceives the sugar the tick transmitted to the victim’s bloodstream and skin as a foreign substance, and makes antibodies to it. That sets the stage for an allergic reaction the next time the person eats red meat and encounters the sugar.
