What are the symptoms of a gelatin allergy?

Hives: Possibly the most common reaction is hives.

Same as any other...: The rashes would not be any different from any other food allergy (eczema or hives), but since gelatin is simply an extract of boiled low-quality beef, the child would probably be allergic to all beef-containing foods if she were allergic to gelatin.

Rash/breathing diff.: Immediate (minutes) and delayed reactions can arise from gelatin allergy. Immediate: hives, respiratory difficulty, throat swelling and low blood pressure. Delayed: a rash that appears 1-2 days after the exposure. Gelatin is found if food and meds/vaccines. Some people react only to food gelatin, others only to pharmaceutical. Kosher gelatin is made out of fish - no crossreact. To reg. Gelatin.
