Mammalian Meat Allergy (from tick bite)
Some people who have had a previous tick bite can develop an allergy to mammalian meats. The allergic reactions to mammalian meat range from mild to life-threatening. Mammalian meats include but are not limited to beef, pork, lamb, kangaroo, goat and venison. Mammals are animals that are born alive and not in a shell.
The tick bite occurs before any allergic reaction to mammalian meats. The allergic reactions to mammalian meat are typically delayed for 2-10 hours after eating the meat. The carbohydrate allergen in the meat to which people react is called “alphagal”.
Some people are so sensitive to alphagal, they react to products that come from or are made from mammals such as cow's milk and gelatine. Any product made from or by mammals may cause allergic reactions. Avoidance of the allergen is therefore very difficult as it may be found in a wide range of products used in foods and medical treatments.

Do you know the correct way to remove a tick?
The Australian tick is particularly good at provoking two very serious allergies, Mammalian Meat Allergy and tick bite anaphylaxis, so it's essential ticks are removed correctly. Remember freeze it, don't squeeze it! If a tick is removed correctly, the likelihood of someone developing mammalian meat allergy is very small.
Watch the National Allergy Strategy's short animation for more information and instructions on how to safely remove a tick.
