The only time that strawberries can cause hives in someone who eats them is if they have a natural allergy to them.

Strawberry allergies are fairly common and the severity of the symptoms varies depending on the person. A strawberry allergy can be mild with the appearance of a few hives on certain areas of the body or it could be more severe, causing the person who eats them to have trouble breathing properly.

Although the latter is fairly rare, there are those who have severe strawberry allergies and have serious reactions if they eat something with these fruit in it.
