Yes, a latex allergy can be linked to food cross-reactions. Some people with latex allergy also react to foods with proteins similar to those in latex. Do not avoid fruits and vegetables you tolerate just because they are linked to latex.
Yes. Some people with latex allergy also react to foods with proteins similar to those in latex. This connection is called latex-fruit syndrome.
Not everyone with latex allergy reacts to these foods. A review found that reported rates of latex-fruit syndrome ranged from 4% to 88% across studies. The studies used different tests and involved different regions and group sizes.
A protein in latex can cross-react with a similar protein in pollen. In people with pollen allergy, this can lead to a positive result on a whole-extract latex skin or blood test. That result can be false, even if the person has no true latex allergy.
In one study, researchers tested plant foods in adults with latex allergy and people with pollen allergy but no latex allergy. People with pollen allergy had more positive food skin tests. The researchers said pollen allergy may help shape which plant foods cause positive tests in people with latex allergy. Discuss your results with an allergist, especially if you also have pollen allergy.
A reaction can cause itching or tingling in the mouth, lips, tongue or throat. Mouth symptoms are usually mild, but more serious reactions can occur.
After you eat a cross-reactive food, symptoms can begin within 5 to 30 minutes. Your lips or tongue may swell, and you may get small bumps or blisters in your mouth. A review also found reports of hives, swelling, asthma symptoms, digestive symptoms and anaphylaxis, a serious allergic reaction. Discuss food reactions with your doctor.
For food allergies generally, skin contact with a food allergen can cause hives or other skin symptoms. Wash it off with soap and water so it does not get into your mouth, nose or eyes.
Smelling food or being near it alone does not cause a food-allergic reaction. Breathing in food protein is different. It can cause a reaction in rare cases, usually around cooking. These points are general food-allergy guidance, not specific findings about latex-fruit syndrome.
Keep eating fruits and vegetables you tolerate. A latex allergy alone does not mean you need to avoid them.
A positive test to a related food does not automatically mean you must avoid it. In general, keep eating foods you already eat without a reaction. That applies even after a positive food-allergy test. Discuss uncertain results with an allergist and ask for a plan tailored to your reactions.
Ask about ingredients and latex gloves before you eat. You can call ahead, then ask again at the restaurant.
Ask how the dish is handled and whether it could come into contact with something you are allergic to.
Ask whether the ingredients have changed.
Ask whether food handlers wear latex gloves. Tell them about your latex allergy and ask for your food to be prepared with non-latex gloves.
Latex proteins can transfer from gloves to food and kitchen surfaces. Rarely, very sensitive people have become sick from food prepared by someone wearing latex gloves. That is latex exposure, not a cross-reaction to the food itself. Avoid takeaway food prepared or served by people wearing latex gloves.
Call 911 or your local emergency number right away for a serious allergic reaction. Anaphylaxis is a serious allergic reaction that can begin quickly and may be life-threatening.
Signs that call for emergency action include:
Sudden swelling of the lips, mouth, throat or tongue.
Very fast breathing or trouble breathing, including wheezing, choking or gasping.
A tight throat or trouble swallowing.
Blue, gray or pale skin, tongue or lips; on black or brown skin, the change may be easier to see on the palms or soles.
Sudden confusion, drowsiness or dizziness.
Fainting when the person cannot be woken.
A child becoming limp or not responding as usual.
An itchy, raised or swollen rash may also occur.
If an epinephrine auto-injector is available, use it right away. Call for emergency help, too. Lie down; if breathing is difficult, raise your shoulders or sit up slowly, and if pregnant, lie on your left side. If symptoms have not improved after 5 minutes, use a second auto-injector if you have one. Do not stand or walk, even if you feel better.
Yes. Food symptoms can come from a food allergy, an intolerance or another food sensitivity. A food allergy is an immune system reaction to specific food proteins. Food intolerance does not involve the immune system.
Intolerance symptoms are more likely to involve digestion. They usually begin a few hours after eating. Belly pain, nausea, gas and diarrhea can also happen with food allergies, so these symptoms alone do not identify the cause. Talk with your doctor and a dietitian about food reactions, especially if symptoms keep coming back.
An allergist can start with your history of latex exposure, food reactions and symptoms. Be ready to name the products and foods involved. Describe how you were exposed, what happened and how long your symptoms lasted.
For suspected latex-fruit syndrome, skin testing may use fruit. Blood tests can measure specific IgE, an allergy-related antibody, to latex. They can also measure it to foods such as banana, kiwi and avocado. In one study, 27 of 100 positive food skin-prick tests were linked to clinical symptoms. Discuss your history and results with your allergist. Do not use a positive result alone to decide which tolerated foods to avoid.
Yes. If you have a food allergy, ask for a written action plan that explains what treatment to use during a reaction. Ask your allergist what applies to you and how and when to use an epinephrine device.
Your plan can list your allergens, symptoms, treatment instructions and emergency contacts. Share the plan with caregivers, keep it where others can find it and make sure they know what to do. General food-allergy guidance advises carrying two epinephrine doses. Ask your allergist what applies to you.
Cooking does not always remove food allergens. A cooked food is not automatically safe if you are allergic to it. Cooked potato is not usually a problem for people with latex allergy. But peeling raw potatoes can cause contact reactions. Discuss your reactions and foods that may cause problems with your doctor.
Can poinsettias cause a reaction in someone allergic to latex?
Yes, a reaction is possible. One report described a woman with latex allergy who got a rash after exposure to a poinsettia. Poinsettia sap can irritate skin and eyes, especially in people with latex allergy. Wash your hands after handling the plant and avoid touching your eyes or mouth.
