Are some people allergic to potatoes?

Posted by Rockney Briskey on

People can be allergic to both raw and cooked potatoes. ... Symptoms of a potato allergy range from mild to serious. They may affect the skin, respiratory system, and digestive tract. A potato allergy can also trigger a life-threatening reaction called anaphylaxis.

What are the symptoms of a potato allergy?

If you have a potato allergy, you may experience an allergic reaction immediately upon touching or tasting potato. This reaction can also occur up to several hours later.

While cutting or peeling potatoes, you may experience a rash on your hands. If you take a bite of food containing potato, you may also feel a tingling sensation on your lips.

Typical symptoms include:

  • sneezing
  • runny nose
  • watery, swollen, or itchy eyes
  • sore or scratchy throat
  • itchy skin or an eczema-like rash
  • hives
  • swelling of the mouth, tongue, or throat
  • difficulty breathing
  • tingling on the lips
  • rapid heartbeat
  • wheezing
  • vomiting
  • diarrhea
  • a drop in blood pressure
  • anaphylaxis


If you have a potato allergy, you’ll typically experience symptoms that respond readily to medication. Sometimes, a life-threatening allergic reaction called anaphylaxis may occur.

Anaphylaxis can begin with mild allergy symptoms, such as a stuffy nose, watery eyes, or hives. Most allergic reactions don’t escalate to anaphylaxis, though they must be monitored carefully to prevent its occurrence. Anaphylaxis is a medical emergency that requires immediate attention.

Additional symptoms of anaphylaxis may include:

  • flushed or pale skin
  • swelling in the throat
  • swollen tongue
  • sensation of heat throughout the body
  • rapid, weak pulse
  • trouble breathing
  • nausea
  • vomiting
  • diarrhea
  • dizziness
  • confusion
  • fainting
How common is a potato allergy?
Potato allergies can affect anybody, although they are relatively uncommon. Researchers do not know how many people have a potato allergy, but one 2017 study that tested 2,000 people in a hospital allergy unit found that 10.1% were allergic to potatoes. Most of these people were allergic to raw, but not cooked, potato.
