Fish Allergy Facts: Why I Can Eat Tuna Without Dying (According to My German Wife, Who Is Not a Doctor)

I was born with a pretty wicked allergy to fish. My parents first discovered it at Disneyland when I was just a little kid; we were tossing chunks of fish to the dolphins and the juices ran down my hands and arms, causing redness and swelling, which earned me a hasty trip to the emergency room. “Oooh, look Mom! Flashing red lights and a siren! This is WAY better than Pirates of the Caribbean!”

Since then I’ve avoided fish as if my life depended on it, because… it kinda does. Salmon, halibut, cod, catfish, herring, anchovies, trout… all of them cause a rapid allergic reaction when they touch my skin — especially my lips or the inside of my mouth. And the sensation is truly unpleasant, like swelling, throbbing, burning, itching and aching all wrapped up into one perfect pain. Like it was designed specifically by God himself to punish me for being a naughty 8-year-old boy who should have known better than to burn all those tiny little ants with a magnifying glass.

But the real danger would be if I ever ingested enough fish to cause my entire body to freak out and my windpipe to swell shut. That’s called anaphylaxis, and I don’t know about you, but I think it sounds like just a barrel of laughs. Luckily, I could never really consume enough to cause such a reaction unless I decided to chug a glass of fish juice or swallow a fistful of fish oil capsules. And that wouldn’t be an accident at all; that would be suicide.

Oh sure, I’ve flirted with fish a few times over the years. You know, just to see if I was still allergic. Like, at a friend’s house, I once touched half a fish stick to my lip only to spend the remainder of the evening looking like a 5th grader with the world’s most aggressive case of oral herpes. And then one time, during a work meeting in the mid-2000s, my entire office went out to lunch at a Japanese restaurant. We all ordered miso soup, and I’d never had a problem with it in the past, but this time it was made with real fish broth. It tasted so good I drank that shit right from the bowl, and about one minute later, my upper lip swelled up and stuck out so far I looked like a Simpsons character.

To this day, I really don’t know what fish even tastes like — especially salmon. That stuff looks delicious, but it’s supposed to cause the most intense reaction of them all, so I leave that sexy bitch alone. The one kind of fish I can eat, however, is tuna.

I was about 25 years old when I discovered tuna didn’t mess with me. It happened by accident: One day, I thought I was holding a chicken salad sandwich, but when I bit down, it turned out to be tuna fish, and oh… my… CHRIST was it delicious! That weirdo tuna meat all mixed up with relish and mayonnaise? I was in heaven! It was like discovering a whole new set of taste buds! Crazy taste buds — and they were having a freaky bondage sex party right inside my mouth! And later I discovered I can even eat raw tuna, like at a sushi restaurant! (But if it bumps up against my wife’s sashimi salmon, the party’s over and I’m headed straight back to Fucksville.)

So I’ve been a pretty zealous tuna lover ever since. Wouldn’t you be, after avoiding a delicious type of food over two thirds of your life? Now, I make sure and buy at least three cans of tuna every time I go to the grocery store. It makes an awesome snack, especially if I’m in a hurry. That’s why, the other day when I sat down next to my German wife on the couch to start a movie, I confessed to her I’d just eaten an entire can in like 30 seconds. She laughed and said it’s weird that I can eat tuna but no other fish. Then she went on to speculate as to the reason, saying:

“Maybe tuna is not really a fish. Maybe it’s a water chicken.”

  1. I really wonder about this! There may be a few other fish that you okay to eat as well, since more of the canned tuna meals are not completely tuna. I know that Chicken of the Sea uses a couple different kinds of cheaper fish, mixed with the tuna. Have you spoken with an allergist about it? It sounds like a really fun adventure, nonetheless.


  2. You would fight a hard fight against my two cats to eat tuna in my house … the cats are all over a person holding a tin of tuna in their hands. And make it entirely clear that eating tuna means to share! Hail to my feline overlords.

  3. Isn’t there a brand of canned tuna that is called “Chicken of the Sea” or something like that? I searched for it while typing this out and yes, yes there is.

    Maybe this canned tuna stuff have not only lost taste and nutrients, but also their allergens.
    Here are some references for many contemplative evenings:

      1. Hmmm…
        Read the books!
        Or … maybe it’s the soy sauce? (Naturally brewed) soy sauce eliminates the evil allergens!
        Make a field test: Eat Rollmöpse (rolled pickled herring) with
        a) no soy sauce; b) with some dashes and c) with a soup-spoon of soy sauce
        Eat with fingers, fork or chopsticks and repeat the experiment with maties, eel and sea mussels.
        Note down the results carefully, then write a book like “Fish allergy as a function of monosodium glutamate in the reflection of European an American history with simultaneous consideration of social- erotic whatnots”.


  5. There must be something different about tuna. Something that makes it different from all other fish. I think tuna flesh is very “meaty”, not at all like that of any other fish I know. I once had a piece of shark when I was in Asia, and it tasted like tuna. So maybe you could eat sharkfish, too, but admittedly, they’re rare in the North Sea. (But so are tuna.)

    I’m sorry you’ll never find out how REAL fish tastes (and I don’t mean trout, I mean those animals from the salty waters of some ocean), but on the other hand: I have allergies, too, and must be careful about what I eat, especially with cheese. I’d love that cheese with the blue mold so much, but the second bite will get me to the ER. And it’s not just about getting red or swollen, it’s serious respiratory problems. (Nothing a good dose of cortison couldn’t help, and no problem if you have your medication with you, but your friends might be worried, so I’m avoiding it.)


  6. I had almost exactly the same experience with the exception of trying most fish fresh and salt / shellfish / amphibian and mollusk. Tuna I was always able to eat out of can – then ventured into fresh tuna in my 20’s as I discovered Sushi. Today still highly allergic to all from the sea with the exception of Tuna – Octopus Grilled – Swordfish and Shark ( think like tuna red steak like meat ) – good luck experimenting. BTW My theory is the minuscule level of parvalbumin ( major fish allergen ) in tuna :)


  7. I am allergic to fresh tuna and salmon as well as most finned fish. I am able to eat canned tuna and canned salmon. I have had this allergy since age 2, now age 65. A coupe of years ago, I discovered I am able to eat cod and pollack, both of which are mild. I have to be very careful about cross contamination or shrimp cooked in or near fish. I am able to eat shellfish, scallops, and oysters. Strange!!


  8. This is fascinating! I too have a severe allergy to all fish… apart from Tuna. Salmon is also my worst allergen, leaving me swollen and usually extremely sick. The comments in this article have given me a great insight into an allergy I thought was just playing games with my mind.

    I’m also allergic to only Cashew and Pistachio nuts, and no others. Which is great fun explaining to people!


  9. And here I though I was alone in the world with my fish – except tuna – allergy.
    Salmon is my number 1 enemy. It just packs me straight to the hospital.

    I have to confess, I’ve read this anxioulsy actually hoping that your wife (that is not a doctor) had had a real insight on this fish allergy glitch…..

    Then I got to the end.. the question still remains out there but at least I had a laugh… (and know I know that other people have the same condition!) .. I like her sense of humour. My best friend is German.. they don’t normally have a good sense of humour. Ha!


  10. I truly thought this was about to be some life-changing insight as to why the same thing happens to me….but it wasn’t…just funny as hell!! LOL Well guess I will forever just wonder….


  11. My brother is also allergic to all fish but not Tuna and Swordfish. He can eat seafood as well. My youngster son, however turned out to be allergic to ALL fish, including tuna… seafood is ok though… Allergies are interesting…

    My son was also allergic to milk but outgrew it and out of the blue became allergic to peanuts. And he used to eat peanut butter by the spoon… Same as other comments above, cashew, pistachios and macadamias seems to have similar allergens…



  12. Same here, i am allergic to all fish except tuna .been wondering about the reason for it no luck. The interesting thing is two years ago i discovered that i have no allergic reaction towards Salmon .my god what a blessing. I felt the same way you felt about tuna


  13. wow.. I am in the exact same situation. Any type of fish, fresh water or salt would cause anaphylaxis and good shot of Epi to ease it… or a trip to the ER. have been wondering about tuna.. it just LOOKS like red meat lol… may try some soon… epi pen handy of course…
