A Fish Allergy is somewhat a less common form of food allergy and mostly affects adults more than children, and amongst adults, it affects women more than men. A fish allergy is different from a shellfish allergy as it is the one where the immune system triggers and reacts to finned fish such as halibut, salmon, or tuna.

Fish allergies mostly develop during early childhood but unlike lactose or milk allergy most fish allergies usually persist all the way through adulthood.

A fish allergy doesn’t necessarily only trigger by the consumption of fish, but a person allergic to fish can also develop symptoms on touching or consuming the byproducts of fish.

A few steps that can help you protect yourself from developing symptoms if you have been diagnosed with a fish allergy are:

  1. Be careful while shopping for groceries:  Even in the cleanest grocery stores that follow all the necessary steps to ensure hygiene, there are possibilities for surfaces, wrapping, racks or containers to be exposed to fish residue if the store has a fish and seafood department. Therefore, always be extra careful when shopping in a grocery store that also sells fish.
  2. Read Product Labels:  Always make sure you carefully examine and read the labels and ingredients while purchasing edible products and if you’re unsure about any fish component refer to your smartphone.
  3. Be extra careful while dining outside:  When dining outside, especially in an Asian Restaurant, be sure to highlight your fish allergy to your server as most Asian traditional dishes use fish or fish stock as a base for preparation. Thoroughly check the menu and if you have doubts always crosscheck and confirm with your server.
  4. Avoid eating at places that serve fish: If possible, avoid eating in restaurants that serve fish as cross-contamination can also trigger allergic reactions.


Following a few careful dietary restrictions under a doctor’s guidance, taking precautions in general and especially while traveling, and always being completely aware of what you are consuming can considerably help you in avoiding fish allergies.
