Latex is a milky sap produced by rubber trees. The sap is blended with chemicals during manufacturing to give latex its elastic quality. Natural rubber latex is often found in rubber gloves, condoms, balloons, rubber bands, erasers and toys. If you are allergic to latex your body treats latex as an allergen and sets off an allergic reaction.
Do you have a known allergy to latex, and testing revealed a positive allergy to food? Or vice versa—are you allergic to certain foods, and your test revealed a positive allergy to latex? There are similar proteins in natural rubber latex and certain foods most types of fruit or nuts , so cross-reactivity can occur. This means that if you have a latex allergy, you may experience allergic symptoms to certain foods because those culprit foods have similar proteins to latex. Likewise, if you have an allergy to certain foods, you may experience allergic symptoms when coming into contact with latex.
Latex allergy reactions usually break out after your skin comes into contact with the substance. This is why individuals with these allergies avoid touching items that are made with latex, such as balloons and surgical gloves. Bananas belong to a group of fruits and vegetables known to be cross-reactive with latex allergies.
Latex is found in a variety of products, from everyday household items to many articles used in routine medical and dental care. An allergic reaction to natural rubber latex is actually a reaction to a protein contained in the sap of the Brazilian rubber tree Hevea brasiliensis. This sap is used in manufacturing latex products. If someone who is sensitive to this protein comes in contact with it by touching or breathing it, an allergic reaction can occur.
