Fish Allergy

By admin

Who wouldn’t love to dine at a seafood restaurant? Well, those who have fish allergies of course. No matter how much they want to enjoy a buttered salmon steak or any other fish dish, they just can’t. There is also a risk in ordering a non-fish dish because the skillet, spatula, or oil used to cook the food may have been used to cook fish.

Fish allergies prevail among countries wherein fish is a part of their staple diet, like in Spain, Japan, and Scandinavian countries, and affects around 20 percent of all populations.

What makes some fish allergenic?

Fish allergies are caused by the protein in the flesh of fish. Fish oils and fish gelatin, even if they are not made of fish meat, can still trigger allergies because these products may have been contaminated by the proteins from the fish meat.

Cod, salmon, trout, herring, sardines, bass, orange roughy, swordfish, halibut, and tuna are fish known to cause allergic symptoms, and oftentimes severe anaphylactic reactions.

However, there are times when people who are allergic to one type of fish, such as cod, will also react to other fish, such as hake, haddock, mackerel and whiting. This happens because the protein allergens of these fish are similar.

When it comes to preparation, raw fish can be more allergenic than cooked fish because heat can denature the allergenic proteins, but that is not always the case. Some people can be allergic to cooked fish, but not raw fish.

What are the symptoms of a fish allergy?

In highly sensitive people, the mere smell of fish can trigger their asthma, and eating foods cooked in reused cooking oil, or using utensils and containers that may have been used in storing or cooking fish can cause anaphylaxis, a severe life threatening allergic reaction. Reactions can be immediate, or delayed for as long as 24 hours.

More common reactions to a fish allergy are the same as symptoms of other food allergies which can affect the skin, the digestive system, and the respiratory system. Specifically, there could be presence of urticaria (hives), eczema, and angioedema (swelling), itching, upset stomach, loose stools, vomiting, cramps, gas, vomiting, nasal congestion, shortness of breath, wheezing, asthma, heart burn, lightheadedness, or fainting.

How to live with a fish allergy?

Find out which types of fish trigger your allergy so that you can eliminate them from your diet. But if you are like majority of fish allergy sufferers, the best thing to do is to avoid eating all kinds of fish altogether.

Take extra precaution when dining out or eating foods prepared by others. Even if it is not at a seafood restaurant, check if the chef uses the same skillet or reuses the oil to cook both meat and fish. If this is the practice then there is a possibility that the materials may have already been contaminated with fish proteins. Opt not to eat at all rather than risk an allergic reaction.

Watch out also for typical condiments, sauces, or dressing that may contain fish proteins such as Worcestershire sauce, Caesar salad, caviar, roe (fish eggs), or imitation seafood often used in sushi.

Among food allergens, fish is the easiest to avoid, but its manifestations can be most severe. So if you suffer from a fish allergy, educate others about your sensitivity. Make sure that you are aware of all ingredients that may indicate fish protein content in prepared or processed foods. Wear a Medic Alert badge, and carry an injectable adrenaline syringe, just in case of a sudden allergy attack.

My brother and his wife have just heard of my severe allergy to fish and now they enter the house with a strange odor present with a cologne scent with it. Now my throat is dry, scratchy, and I almost had an asmtha attack yesterday with them and used my inhaler and took two benadryl. They say taunting things to me as: Does your chicken taste like fish? Does this restaurant serve fish? They are going to order fish but luckily no fish was in this restaurant. I never told them I was allergic to fish and they knew I was allergic to eggs and then they cooked eggs everytime they could, frying okra, eggplant, and meat in eggs and flour. But this new thing has them really picking at me and I have left the residence to escape the odor. I am so sleepy from benadryl and lots of water. They go back to Texas in the morning and I hope I recover. Tell me what to do? I know they both use fish oil for health purposes and wonder if they are using it on the sofa where I sit and recline. I am on chemo too and I am not well at all.
Please tell me how to ck. to see if fish is actually in the house on a sofa or a surface…

Actually,living with any food allergy is no longer a main undertaking, it is now just a small adjustment to your life-style.

I am a Navy Lt. and while being in the Pacific two years ago I began to wheeze and developed this irritable rash all over my entire body. I was checked by our medical staff and flown to the nearest hospital and was given injections of prednizone and a dose pak of Medrol. Next I had to be placed on life support with all the tubes in my nose and an incision in my trachea with a tube inserted there into my lungs as my airways were swollen from the severe allergy I was having. The attending Dr. asked me what I had for my last meal and I told him some fish we caught in our nets and he said, “You are lucky to be alive.” Later I recovered and by later I mean weeks… and I took a battery of allergy test and fish was my worst nightmare of an allergy. I will never forget this ordeal and my wife cannot cook fish in the house and I can’t go into a restaurant that is cooking it. So the next time someone tries teasing you Jane, Ask them if they have enough insurance to cover your illness in ICU. This is a very serious condition and not easily handled except with avoidance 100%.

When I have eatten salmon or tilapia I break out in hives 48 hours later and it takes up to a month to clear the hives. I have seen an allergist; a skin test and blood/antibody testing for all fish and shellfish were performed. I am told my reaction is atypical of a food allergy. Is there something else going on?

We have a lot of customers with fish allergy, they take our omega-3 supplement from algae, so if you cant eat fish and your worried about a lack of long chain omega3 (EPA, DHA) in your diet, take an algae supplement instead. There are no proteins associated with fish oil allergy

At 54 I discovered I have a fish & shellfish allergy!
I have suffered for 33 years with occasional sharp pain and much discomfort.
I cannot find any link on the Internet with regards to my specific condition with regards to this salmon & herring allergy.
With no obvious help and doctors not helping, I wish to state here that this allergy caused my external haemorrhoids/piles and the painful attacks that followed.
Only 3 years ago my throat became swollen and then closed up after eating my first lobster. Only later after realising that I was allergic did I prove that this was happening to the other end with these fish. Apologies for stating this, but I am sure there are many people living with this dreadful condition that do not know it may be due to a fish allergy swelling and closing up the area around their tail end.

my 4 year old grandaughter only has to walk into the house where we are cooking fish and starts getting hives. We didnt know this until recently. Before we discovered she cannot touch a fresh caught trout or perch and she gets big welts on her face and is misreable. She comes from a fishing family and we no longer do fish when we know she is coming over. She will even ask us if she gets ice cream bar out of the freezer is it by fish. Or if she washes her hands at the sink if there has been fish by there. Once time there was fish water stitting next to the sink on the counter and she leaned over and touched it and sure enough her face and legs started to itch.

The study noticeable a huge difference in the total quantity of nicotine levels present vis-a vis detailed on an smokeless cigarette packet.

The electronic cigarette is making the new generation of smoking popular all over the world.

Either that, or they are using the highly controversial e-cigarette to cover up the fact that the fire was the
hospital’s fault.
