{Abstract}: <B>UNASSIGNED: </B>Alpha-gal allergy or red meat allergy is a rare yet potentially severe allergy. Sensitisation usually occurs when alpha-gal present in the tick's saliva is transferred to humans during a tick bite, prompting the production of IgE antibodies to alpha-gal. Subsequent exposure to mammalian meat or other products containing alpha-gal can lead to allergic reactions.<BR><B>UNASSIGNED: </B>A previously healthy man in his sixties was admitted with acute anaphylaxis. A history of multiple tick bites and recent consumption of mammalian meat raised suspicion of anaphylaxis caused by alpha-gal syndrome.<BR><B>UNASSIGNED: </B>A diagnosis of alpha-gal syndrome was given based on elevated alpha-gal IgE antibodies, and further supported by medical history and clinical assessment. He was discharged with dietary instructions to eliminate food and products containing alpha-gal, and to manage allergy symptoms and anaphylaxis according to local guidelines.
