What is Pork Allergy: Causes, Symptoms, Treatment, Prevention
Do you have pork allergy? Clemens von Pirquet was the first to describe allergies as a exaggerated reaction of the immune system in response to exposure to foreign proteins in 1906. Allergies are the sixth largest cause of chronic diseases in the United States according to Asthma and Allergic Foundation of America (2002). Allergies are caused by hypersensitivity of the immune system to substances, situations, or physical states that is harmless to most people. Our immune system produces antibody immunoglobulin when encountering an allergen which are the external substances that provoke allergies.
The antibody attempt to destroy the allergen and protect itself. But this process let the other cells signals to release certain chemical called histamines which can cause an unwanted response to our body if large amount of it are released. Pork allergy can be mild, severe, or in some cases it can be fatal. While more common in children, allergies can affect people at any age. Common allergens that may lead sometimes to severe reactions are medication specifically antibiotics, penicillin or other drugs like aspirin and anesthetics, substances, foods particularly peanuts and sea foods and insect stings. These can be swallowed, inhaled, injected, come into contact with skin, airways or eyes. Most of the people have allergies.
However, pork allergy is quite uncommon. As allergies to meat are very rare, it is more common that the chemicals and preservatives specifically the 65-kDa protein found in the meat are the ones that cause the allergic reactions such as abdominal symptoms, sneezing, rashes, and breathing problems. Pork allergy can develop any time in life. Scientists until now have no understanding why some people are allergic to certain foods and can offer no cure of it. Increasing population is considered to be one of the reasons, however, there are theories that more germ-free atmosphere could be responsible for the overreaction of the body's immune system to harmless foreign protein. Let us discuss pork allergy.
Causes of Pork Allergy
Some of the causes of pork allergy are:
- The chemical used for processing the meat or the meat itself can cause pork allergy.
- Chemicals used as preservatives in meat.
- Stabilizer such as papain(used for meat tenderizer) and casein (used as a stabilizer).
Signs and Symptoms of Pork Allergy
- Signs and symptoms may vary from person to person and depend on how severe the pork allergy is and how much pork was consumed or come in to contact with.
Severe anaphylactic reaction as a symptom of pork allergy. A severe potentially deadly allergic reactions which include drop in blood pressure, loss of consciousness, rapid or weak pulse, swelling of throat and blockage of airways that may lead you to severe shortness of breathing. If this happens someone around you or exactly to you, seek an emergency call .
- Abdominal symptoms such as abdominal pain and bloating are also symptoms of pork allergy.
- Rhinitis also called runny or stuffy nose.
- Hives or skin rashes.
- Nausea and vomiting.
Tests to Diagnose Pork Allergy
See an allergist if you suspect that you have pork allergy. The allergist will usually conduct a blood test or perform a skin test that indicates whether food-specific immunoglobulin E (IgE) antibodies are present in your body.
- Skin test also known as puncture or scratch test for diagnosing pork allergy provides a result for about 20 minutes. The skin on your arm or back pricked with a sterile small probe that contains a small amount of an allergen. If a wheal resembling the bump like a mosquito bite, redness, and swelling develops at the site, it is considered positive.
- Blood test for pork allergy also known as radioallergosorbent test (RAST) measure the amount of IgE antibody to the specific food being tested. It takes about 1 to 2 weeks to know the result.
- Patch testing used to determine if a specific substance causes inflammation reaction to the skin. Adhesive patches treated with some various common allergic chemicals are applied to the back.
Treatment for Pork Allergy
There is no cure for pork allergy, but effective treatment can reduce symptoms that may improve the quality of your life. These are the treatments to prevent an allergy attack caused by pork allergy:
- Not having any contact with the allergen is a good way to manage pork allergy.
- Use of antihistamine to maintain a check on the secreted histamine.
- Epinephrine is used in case anaphylactic reaction tends to occur.
- Use of bronchodilators when the shortness of breathing and wheezing occur.
- Inhale beta agonist as well as corticosteroids.
- Desensitization to get used to the allergens.
- Hospitalization in case of occurrence of anaphylactic reactions because of pork allergy.
- Bromelain, Quercitin, Vitamin A, Eucalyptus, L- Carnitine, and Iron can be taken to reduce the sensitivity caused by pork allergy. But take note, you must seek an advice to your physician first before taking any medicine.
Immunotherapy is an exposure of allergen to some pork allergy patients.
- Pork allergy shots involve in giving injections of allergens in an increasing dose over time.
- Shots and Sublingual Immunotherapy (SLIT) are given to patients of pork allergy with a small dose of allergens under the tongue.
Prevention of Pork Allergy
Below are some pork allergy preventions:
- Know about cross-contamination. It happens when a food you can normally eat comes into contact with a food you are allergy to and in this case it is pork.
- Selection of products for a meal which involves the obligation to read the composition of the product given on the labels.
- Beware of foods made with lard or gelatin to prevent pork allergy. Pork lard is occasionally used in baking and pork gelatin is common. Foods such as marshmallows, candies, ice cream and Jell-O generally contain pork gelatin. Look for foods that contain kosher or halal gelatin or that are vegan-friendly. Many vaccines, particularly flu vaccines, contain pork gelatin.
- Wear a medical alert bracelet or necklace to let others know that you have a pork allergy in case you have a reaction and you are unable to communicate.
- Keeping a diary is another way if you want to figure out which allergens might worsen your symptoms, write down all your activities and what you eat to help pinpoint triggers.
- Be extra careful when you eat outside. Sometimes the kitchen staffs may not always know the ingredients in menu.

Complications of Pork Allergy
People with pork allergy are also at risk of developing complications including the list below:
- Asthma can be a complication of pork allergy. It is a respiratory illness that causes inflammation and narrowing of the airways that leads to wheezing, chest tightness and difficulty of breathing.
- Another complication is eczema which is an inflammatory disease of the human skin described by itching, redness, and oozing vesicular lesions that grow as scaly, hardened, or crusted.
- Nasal polyps is also seen in pork allergy which are growths on the lining of the nose or sinuses.
Prognosis/Outlook for Pork Allergy
The outlook or prognosis for non hereditary pork allergy is excellent. Generally, most infants and young children become more clinically tolerant of their food hypersensitivities. In general population-based studies, shows that about 20% of infants and young children experience resolution of their pork allergy by the time they reach school age and continue to lose their pork allergy into adolescent years.
