Which tick is associated with allergic reactions to red meat?

Allergic reactions to red meat tied to a tick bite come from a condition called alpha-gal syndrome, where the bite sensitizes the immune system to a sugar molecule (alpha-gal) found in most mammalian meat. The Lone Star Tick is the species most strongly linked to this syndrome. Its bites can introduce alpha-gal into the body and trigger IgE antibodies against it. Later consumption of red meat (beef, pork, lamb) can then cause a delayed allergic reaction—often several hours after eating. Other ticks are associated with different diseases or pathogens and are not the primary culprits for alpha-gal–related red meat allergy.
