There are many "classes" in seafood allergy, like crustaceans , mollusks , fish.. WIth a rast test your allergist should be able to test for individual types of fish like tuna, cod, or crustacians like crab, shrimp, lobster, etc. When my son was first diagnosed with food allergies I was told he was severely allergic to all seafood. four years later, when tested again, my new allergist said he is not showing any antibodies in the rast. He said I could introduce him to some if I wanted to find out. My answer NO WAY! (I have had MANY doctors give me BAD INFORMATION in the past, I am much more careful now.) my thought is that he has no antibodies because he has never injested any seafood in his life...why should I introduce him to something they told me a few years ago he was deathly allergic to? We don't live on an island.. he can live fine without fish.. when he gets much older and decides he would like to try it then we can deal with it. Seafood allergy is can be fatal... I would only introduce a questionable food under the advice of a professional allergist and then with much thought.

My daughter has never tested positive to seafood. I have just avoided for the same reasons you have because it's a very allergic food.
She is presently allergic to peanuts, milk and eggs. ...and has outgrown rice, soy and had a hard time in the beginning to corn and peas but now is fine.
I wanted to try to expand her diet a bit and thought maybe I could try tuna.
I didn't realize the different classifications you mentioned above, I think I'll get a hold of the allergist and ask if he has tested her for all different types or not. Thanks for the info.

This thread has reminded me of something that happened to me when I was a teen. My parents took me to the hospital because I was covered head to toe with huge hives. They took me in because the hives were so bad that my legs were turning blue. At the time, I guess not alot was known about allergies but the ER doctor figured out that I had had a reaction to crab which I had eaten for the first time that day. Nothing ever came of it but I have to say, I have never eaten crab again and avoid seafood (other that fish) in general, never liked it. The only other "reaction" (if you can call it that)I had was after eating mussels for the first time, I was violently ill, vomitting, dizzy, crazy but I thought I was gonna die. I don't really think it was a reaction, I probably just ate a "bad" one. My dh and a friend had the same food (it was prepared by the friend) and neither one was ill. Makes me wonder.

Katiee: I'm not sure if I read your post correctly. Did you say you avoid seafood but do eat fish? If so what type of fish do you eat?
I'm definitely not going to try the seafood with her.

I have no problem with fish, except shell fish. I have a bad allergy to shell fish. Andy

I do eat fish, as in cod, salmon etc. but I'm hesitant to try "any" other shellfish because of what happened.

Below is some info I got from allergy web sites. Fish allergy is more common among children, while shellfish allergy is more common among adults.
Both tend to be lifelong allergies. Here is the article:
Fish allergies are more common in children, whereas shell fish allergies seem be more prevalent in adults. Some breast-fed infants have been sensitized to cod via their mother's milk. These allergies do not usually go away or diminish with age. These allergies usually last a lifetime with the reactions becoming more severe with each subsequent exposure.
Fish Allergy
It is estimated that about 22 percent of all populations suffer from a fish allergy. The fish commonly known to cause allergic reactions include cod, salmon, trout, herring, sardines, bass, orange roughy, swordfish, halibut, and tuna.
Severe asthmatic attacks can be triggered by the smell of fish in a sensitive person. Even anaphylactic shock has been reported after eating foods cooked in reused cooking oil, or when utensils and containers have been used earlier for cooking fish.
Shell fish Allergy
The shell fish commonly known to cause allergic reactions include shrimp, crab, crayfish, lobster, oysters, clams, scallops, mussels, squid, and snails.
Shrimp is usually associated with seafood allergies. Those allergic to shrimp often suffer from respiratory allergy. Crab is also a potent allergen. Shrimp, lobster, and craw fish contain common major allergens, making cross reactivity between shrimp and crab, and lobster and craw fish possible.
I'll post more info on exact seafood families later. BTW, Cayley has eaten both tuna and salmon with no problem, as well as clams (in a linguine dish). If allergy testing is coming up, you might want to ask to include fish/shellfish on the RAST list, just to be on the safe side. I've been nervous about fish/shellfish too (all her exposures were prior to the PA diagnosis), but I figure the damage (if any) is done. I'm still going to avoid seafood until she's at least 5 years old.

The Allergy Society of South Africa has a great web site on "Seafood Allergy"
It provides details of testing material used in South Africa which is helpful for the classifications. I would also suggest you look at Brostoff's "Food Allergy and Intolerance" Book, details in the Book Section which also has soon great lists of "allergen groups" and cross-reactivities.

To Peanut Trace: If you were thinking of maybe introducing canned tuna to your child just be careful. If they are milk allergic, many canned tunas' have casein in it. As you probably already know, casein is a milk protein. My son was allergic to milk(now he is 8 and only mildly allergic to milk) and I couldn't give it to him. What do you feed a small child!? PB&J, grilled cheese and tuna. Didn't leave too many options open! LOL. sorry, not a joke but just be careful. I've been through it. B-Well! [img][/img]

My daughter tested positive for shellfish, but she can eat any type of fish. The biggest problem we have is avoiding cross-contamination when the fish is fried in the same oil as shellfish. She reacted this weekend because she was outside while crawfish were being boiled - never ate any.
