A tick bite can lead to a permanent anaphylactic allergy to meat and milk in humans.

The claim that a tick bite can cause a permanent allergy to meat and milk in humans is generally supported by evidence concerning alpha-gal syndrome. Alpha-gal syndrome is a condition where a mammalian meat allergy is triggered following bites from certain ticks, notably the Lone Star tick in the United States. This syndrome can lead to severe allergic reactions, including anaphylaxis, after consuming red meat and dairy products from mammals. There are multiple reliable sources confirming this condition, such as University Hospitals and VCU Health, which describe the rise and spread of tick-linked meat allergies and their serious health implications. The evidence strongly supports the factuality of the claim, though it is important to note that this condition primarily affects certain regions and is not caused by all tick species.
