Food allergies: How to deal with meat allergy

Meat allergy such as to pork, beef, lamb and poultry is uncommon. This might be due to meats being cooked before consumption. Food allergies are relatively common and affects both children and adults. The common food allergies especially in children include peanuts, cow’s milk, eggs, wheat, tree nuts, soy, fish and shellfish. Adults can be allergic to tree nuts, peanuts, fish and shellfish as well as fresh vegetables and fruits due to oral allergy syndrome.

It is important to note that meat allergy is uncommon since cooking reduces the allergic nature of foods by breaking down the proteins responsible for the reactions. In case the protein responsible for the allergy is degraded by the heat, the allergic antibody (IgE) could no longer recognize the protein, thus a reaction does not take place.

Reactions to meat can occur and trigger various reactions after consumption. It commonly includes the usual reactions which occur minutes after eating with symptoms such as the following:

Meat allergy

Some individuals with respiratory sensitivities to cat albumin might also be sensitive to pork meat which is called as pork-cat syndrome and triggered by the comparable structures of pork and cat albumin.

  • Hives and angioedema
  • Respiratory symptoms (coughing and wheezing)
  • Digestive symptoms (diarrhea, nausea and vomiting)
  • Anaphylaxis

Other allergy reactions include food-protein induced enterocolitis syndrome (FPIES), eosinophilic esophagitis and even delayed reactions due the presence of carbohydrates in the meat.

Various forms of meat allergy

Poultry allergy

Reactions to poultry such as turkey and chicken are uncommon. This is due to the cooking process before ingestion which is usually well-cooked than beef due to the issue of food poisoning from poorly cooked poultry.

Some individuals with egg allergy might have respiratory allergy triggered by down feathers which is known as bird-egg syndrome.

Beef allergy

This type of meat allergy is considered common among young children especially those who have eczema and can also occur in some children who have cow’s milk allergy. Many individuals with beef allergy are also sensitive to cow’s milk.

Individuals with this meat allergy might end up allergic to beef gelatin which is also capable of triggering allergic reactions to certain vaccines.

Pork allergy

There have been reported cases of reactions to pork meat as well as meat of wild boar. Some individuals with respiratory sensitivities to cat albumin might also be sensitive to pork meat which is called as pork-cat syndrome and triggered by the comparable structures of pork and cat albumin.

Many individuals who are allergic to cats can end up with symptoms due to the main allergen Fel d 1 and should not be allergic to pork meat.

What is galactose-alpha-1,3-galactose allergy?

When it comes to this allergy, it is triggered by a carbohydrate found in mammal meats including pork, beef and lamb which is capable of severe allergic reactions. The reactions occur 3-6 hours after consumption of these meat.

Most individuals with reactions to alpha-gal were able to eat mammal meats previously. The conventional allergy tests to the commercial allergen extracts of pork, beef and lamb often yield a negative result among those with the allergy.
