Mammalian Meat Allergy (Alpha-gal Syndrome)

Mammalian Meat Allergy (Alpha-gal Syndrome)

Hypersensitivity type may be- Type I Allergy
Immune reactions may be from- IgE
Reactions may occur in- Minutes (Can have a delayed onset of symptoms)

Mammalian Meat Allergy is also known as Alpha-gal Syndrome (AGS) or Alpha-gal Allergy. Mammalian Meat Allergy is caused by being sensitised earlier (being bitten earlier) by the Paralysis Tick.

When people with this allergy consume mammalian meat, a reaction is caused by the Alpha-gal sugar molecule found in the meat. This causes causing an allergic reaction that can range from minor to severe and life-threatening. Mammalian Meat Allergy reactions are similar to those of other food allergies. However, unlike other food allergies, it may, in some cases, have a delayed onset of symptoms 2-10 hours from ingestion. 

What are Mammals? Mammals are a diverse group, but they all are vertebrates that produce milk to feed their young, have hair or fur, have a unique jaw structure and are warm-blooded.

Mammals include Cows, Pigs, Kangaroos, Sheep, Goats, Deer, Rabbit, etc. From mammals, people consume beef, pork, lamb, etc.

While this allergy occurs through foods containing Alpha-gal, it may also occur through exposure to products containing Alpha-gal, such as gelatin-coated medications and mammalian milk (Cows Milk, Goats Milk, etc).

Adrenaline (Epinephrine) is the first-line treatment for Anaphylaxis. After administering Adrenaline (Epinephrine), seek emergency medical attention by calling Triple Zero (000) for an ambulance.

If you are unsure what to do, call Triple Zero (000).

If you or someone you know is suspected of having an allergy, it’s important to discuss diagnosis, symptoms and treatment with a qualified health care provider to understand how to manage individual allergies and also to set up an Allergy Action Plan in the case of a reaction.
