What Is a Fish Allergy?
A fish allergy is not exactly the same as a seafood allergy. Seafood includes fish (like tuna or cod) and shellfish (like lobster or clams). Even though they both drop into the category of "seafood," fish and shellfish are biologically diverse. So shellfish will only cause an allergic reaction in someone with a fish allergy if that person also has a shellfish allergy.
People with a fish allergy might be allergic to some types of fish but not others. Although most allergic reactions to fish happen when someone eats fish, sometimes people can react to touching fish or breathing in vapors from cooking fish.

Even people who own eaten fish in the past can develop an allergy. Some people outgrow certain food allergies over time. But those with fish allergies generally own that allergy for the relax of their lives.
What Are the Signs & Symptoms of a Fish Allergy?
When someone is allergic to fish, the body’s immune system, which normally fights infections, overreacts to proteins in the fish. Every time the person eats (or, in some cases, handles or breathes in) fish, the body thinks these proteins are harmful invaders and releases chemicals love .
This can cause symptoms such as:
- throat tightness
- belly pain
- trouble breathing
- itchy, watery, or swollen eyes
- red spots
- a drop in blood pressure, causing lightheadedness or loss of consciousness (passing out)
Allergic reactions to fish can differ. Sometimes the same person can react differently at diverse times. Fish allergy can cause a severe reaction called anaphylaxis, even if a previous reaction was mild.
Anaphylaxis might start with some of the same symptoms as a less severe reaction, but can quickly get worse. The person may own trouble breathing or pass out. More than one part of the body might be involved. If it isn’t treated, anaphylaxis can be life-threatening.
A kid who has a fish allergy must completely avoid eating fish. Sometimes an allergist can test for allergies to specific types of fish.
Otherwise, it’s best for someone with a fish allergy to avoid every fish.

An epinephrine auto-injector is a prescription medicine that comes in a little, easy-to-carry container.
It’s simple to use.

Staff at your child’s school should know about the allergy and own an action plan in put. Your child’s medicines should be accessible at every times. Also consider having your kid wear a medical alert bracelet.
Every second counts in an allergic reaction. If your kid starts having serious allergic symptoms, love swelling of the mouth or throat or difficulty breathing, give the epinephrine auto-injector correct away.

What Else Should I Know?
If allergy testing shows that your kid has a fish allergy, the doctor will give you guidelines on keeping your kid safe.
To prevent allergic reactions, your kid must not eat fish. Your kid also must not eat any foods that might contain fish as ingredients. Anyone who is sensitive to the smell of cooking fish should avoid restaurants and other areas where fish is being cooked.

Some foods glance OK from the ingredient list, but while being made they can come in contact with fish.
This is called cross-contamination. Glance for advisory statements such as "May contain fish," "Processed in a facility that also processes fish," or "Manufactured on equipment also used for fish." Not every companies label for cross-contamination, so if in doubt, call or email the company to be sure.
Cross-contamination often happens in restaurants. In kitchens, fish can get into a food product because the staff use the same surfaces, utensils (like knives, cutting boards, or pans), or oil to prepare both fish and other foods.
This is particularly common in seafood restaurants, so some people discover it safer to avoid these restaurants.
Fish is also used in a lot of Asian cooking, so there’s a risk of cross-contamination in Chinese, Vietnamese, Thai, or Japanese restaurants. When eating at restaurants, it may be best to avoid fried foods because numerous places cook chicken, French fries, and fish in the same oil.
When eating away from home, make certain you own an epinephrine auto-injector with you and that it hasn’t expired. Also, tell the people preparing or serving your child’s food about the fish allergy. Sometimes, you may desire to bring food with you that you know is safe. Don’t eat at the restaurant if the chef, manager, or owner seems uncomfortable with your request for a safe meal.
Also talk to the staff at school about cross-contamination risks for foods in the cafeteria.
It may be best to pack lunches at home so you can control what’s in them.
Other things to hold in mind:
- Make certain the epinephrine auto-injector is always on hand and that it is not expired.
- Don’t feed your kid cooked foods you didn’t make yourself or anything with unknown ingredients.
- Carry a personalized "chef card" for your kid, which can be given to the kitchen staff.
The card details your child’s allergies for food preparers. Food allergy websites provide printable chef card forms in numerous diverse languages.
- Tell everyone who handles the food — from relatives to restaurant staff — that your kid has a fish allergy.
