Fish Allergy


Fish allergy is one of the most common food allergies, especially in adults. Fish can be incorporated into processed foods in powder, oil, or raw form.  Luckily though, fish is rarely a hidden ingredient in other foods – in most cases, this fish ingredient will be clearly labeled. One exception is that sometimes fish allergens are not clearly indicated if the ingredient is a fish oil.

When dealing with a fish allergy, cross-reactivity is common – this means that someone who has had an allergic reaction to one species of fish is rather likely to be allergic to at least one other species.  However, recent research indicates that you may still be able to safely consume some fish species.  This technicality is a matter you should discuss with your NYC doctor at our asthma and allergy clinic.

For complete safety, it is recommended that fish-allergic individuals try to avoid all types of fish.
