A pork allergy is an adverse immune response after consuming pork and its byproducts. It is also called pork-cat syndrome because most pork allergies are related to cat allergies. People develop this pork allergy sensitivity due to an allergic response to cat serum albumin that cross-reacts with albumin in pork. Other causes of pork allergy are unknown. Undercooked pork meat or dried and smoked pork products tend to cause more reactions than well-cooked pork meat.

There may be other foods not listed that contain pork ingredients. Pork is also hidden in some detergents, cleansers, dish liquids, and soaps. It’s important to read labels on packaged foods. Look for words like hydrolyzed animal protein, gelatin, and monostearate. These proteins come from animal fats.

Pork Allergy Diagnosis

An allergy blood test or provocation test works best to diagnose this allergy. A blood test measures the IgE antibodies in your blood responsible for your allergic reaction to pork. This type of pork allergy testing does not require preparation as most other tests do such as a pork allergy patch test; however, you may have to wait weeks to receive your test results. During this time, refrain from eating pork.



An allergy provocation test, also known as a food challenge, requires you to eat pork in a clinical setting. An allergist will recommend this test if you have a known cat allergy. You should not attempt this challenge at home, as it can cause a severe pork allergy reaction. Your doctor will have emergency medical equipment close by if needed.

Pork Allergy Treatment

Treating a pork allergy begins with avoidance. Adopt a new diet and carefully research new food items you want to try to ensure there are no pork ingredients in it. A food allergy specialist can help you manage your diet and symptoms. Contact NY Allergy & Sinus Centers for more information.

In the event of an allergic reaction, over-the-counter allergy medication can soothe some of your symptoms. You may also need a prescribed cortisone cream to soothe your pork allergy rash and inflammation. Since pork allergy is a severe food allergy, you should also carry an epinephrine injection. Your allergist will train you how to administer the medicine.
