Have had strawberry daiquiri in past, but recently had a few drinks of one and face started burning and got hives? New allergy to strawberries?

Food allergy. The development of allergic antibodies requires the exposure to the food and can develop after years of a food consumption without allergic symptoms. Rarely, food reactive antibodies may develop from cross-reactions with other non-food allergens. A good example of cross-reactivity would be melon allergy in ragweed allergic persons or banana allergy in someone with latex allergy.
