Yes, it is possible that this was an allergic response. The thing about allergies is that often you me response will get worse with the second, third exposure and so on.

It is possible that you're suffering from an allergy. In these situations, when there is exposure to fruits, the mild itching in the throat that you're experiencing could be due to an allergy to pollen residue left on the fruits and vegetables. There is a possibility that there could be a mild intrinsic allergy to one of the fruits themselves. Wash your fruits and vegetables thoroughly prior to eating them. If symptoms persist or become troublesome, I recommend that you see an allergist.
