If you experience discomfort or cold-like symptoms when you eat celery, it may be a sign that you have an allergy or intolerance. These symptoms can range from mild to severe and can sometimes worsen over time.
In this post, we'll explain the symptoms of celery intolerances and allergies, how common they are, and what you can do to figure out whether or not you have one.

What are the symptoms of celery allergy?
The symptoms of a celery allergy vary. Some can be reminiscent of a cold or flu, while others affect your stomach and digestive system or even cause breathing difficulties. If you have an allergy to celery, the symptoms include:
- Coughing, sneezing and runny nose
- Shortness of breath
- Nausea and vomiting
- Itchy or swollen eyes
- Stomach pain
- Lightheadedness
- A skin rash
- Swollen lips or throat
In some extreme cases, an allergy can result in anaphylaxis.
In most cases, if you have a celery allergy your symptoms will be worse if you eat raw celery rather than cooked celery.
What is food intolerance?
A food intolerance is caused by your body's inability to process or metabolize a certain type of food, which leads to painful or unpleasant symptoms. This is unlike an allergy, which is your body mistaking the food as a threat, triggering a response from your immune system. Both an intolerance and an allergy can develop at any stage of your life.
How common is a celery allergy?
Celery allergies and intolerances are surprisingly common, however, because symptoms are far more noticeable after eating it raw, it's most commonly diagnosed in regions where people eat high amounts of raw celery. This includes Switzerland and France, where between 30% and 40% of people with food allergies have a reaction to celery.
So, if you experience any of the above symptoms after eating raw celery, there's every chance it's because you have an allergy or intolerance.
What should you do if you think you have a celery allergy or intolerance?
If you think you might have a celery intolerance or allergy, you should stop eating celery or food that contains it — even if it's cooked. This isn't just because the symptoms can be uncomfortable, but they can worsen over time.
To find out if you have an intolerance or allergy so you can manage your diet, a food sensitivity test or allergy test is a fast and easy way to find out for sure.
How do you test for a celery allergy or intolerance?
There are several ways you can find out whether or not you have a celery allergy or intolerance, with varying degrees of accuracy:
- An elimination diet involves removing food that contains celery from your diet to see whether your symptoms stop.
- You can start a food diary to monitor what you eat and when you experience symptoms, to see if there are any patterns.
- You can speak to your doctor or healthcare provider and ask them for advice.
- A food intolerance blood test or food allergy test can help you identify an intolerance or allergy, even if it's not celery.
What foods should you avoid if you have a celery allergy or intolerance?
If you have an allergy or intolerance to celery or suspect that you do, you'll want to avoid eating any type of food that contains celery, including celeriac and celery seeds. However, other foods to be mindful of that regularly contain celery include:
- Soups
- Sauces
- Salads
- Stews
- Juices
You may also develop an allergy to carrots and spices, so this is also something to be mindful of if you have a celery allergy or intolerance.
FAQs
Why are symptoms worse with raw celery than cooked celery?
Cooking can break down some of the proteins responsible for triggering a reaction, which is why many people with a celery sensitivity tolerate cooked celery better than raw — though this isn't guaranteed for everyone, especially those with a more severe allergy.
Is celery allergy linked to other allergies, like birch pollen?
Yes — celery allergy is part of a recognized cross-reactivity pattern with birch pollen and certain spices, sometimes called celery-birch-mugwort-spice syndrome, which is part of why carrots and spices are also worth watching if you have a celery allergy.
Can celery salt or celery seed trigger a reaction even if I avoid fresh celery?
Yes — both contain the same allergenic proteins as the fresh vegetable, so avoiding celery entirely means checking for celery salt, celery seed, and celeriac too, not just the stalk itself.
Whether you're dealing with a true celery allergy or an intolerance, getting an accurate diagnosis matters, since celery can hide in soups, sauces, and seasonings more often than people expect.
