Can Someone With a Shellfish Allergy Eat Caviar?

One of the most frequently asked questions that I get is whether someone with a shellfish allergy can eat caviar.

If you only have a shellfish allergy you can eat caviar. However, this comes with the caveat that people who have other seafood allergies in addition to shellfish allergies may not be perfectly safe from caviar.

We’re going to take a closer look at seafood allergies so that we can distinguish shellfish allergies from the rest. If you’d rather learn more about when you can expect to experience certain reactions, I’ll explain when to eat caviar and when to avoid it.

Can You Eat Caviar With a Shellfish Allergy?

If you know that you have a shellfish allergy and nothing else, then you won’t have to worry about getting sick from eating caviar.

Unfortunately, many seafood allergies go hand-in-hand, and this may mean that you have an accompanying allergy that can be triggered by the allergens in caviar.

In this section, we’re going to take a closer look at the main seafood categories and the allergies associated with them, including:

  • Fish
  • Shellfish
  • Crustaceans
  • Others

We’ll also go over some of the common symptoms of seafood allergies and how you can seek treatment to ensure that the symptoms don’t cause any permanent damage or worse.

Types of Seafood and Their Allergies

The following table will go over everything you need to know about the various classes of seafood. Keep in mind that most seafood allergies will be within one of the following classes, but some people also have an overlap where several seafood allergens will trigger a reaction.

ClassTypes of seafood in the class
FishBass, tuna, salmon, trout, herring, carp, haddock, sardines
ShellfishMussels, octopus, squid, scallops, clams
CrustaceansShrimp, crawfish, crab, lobster
OtherCaviar, imitation crab, roe

Most seafood allergies are split into three categories: fish allergies, shellfish allergies, and crustacean allergies. Unfortunately, there isn’t a lot of info on allergic reactions to caviar because of the relative rarity.

What has been confirmed is that anaphylactic shock in response to eating caviar has occurred, as evidenced by The Journal of Allergy and Clinical Immunology.

There are a few reasons why there may not be that much data about allergic reactions to caviar, and perhaps the most obvious one is that not that many people eat caviar in the first place.

The high cost of caviar means that it has historically been reserved for the upper classes. While caviar may now be easier to find than it once was, it is still relatively expensive, and not many people would think of spending their money on a tin of beluga caviar.

If you’re allergic to other kinds of seafood like shellfish, you may not be allergic to caviar, but you should still be careful around it if you’re not sure whether or not you’ll suffer a reaction.

People eating caviar for the first time, like people trying caviar for keto, are at the highest risk of experiencing an allergic reaction, especially if they typically don’t eat seafood.

One of the main indicators that you may be allergic to caviar is if you’re allergic to the parent fish. If you can’t consume fish like sturgeon, then there’s a heightened chance that you won’t be able to eat a sturgeon’s eggs, either.

Seafood Allergy Symptoms

Here are some of the major symptoms of a food allergy, including shellfish allergies:

  • Rashes and itchy skin
  • Breaking out in hives
  • Reddening of the facial skin
  • Swollen throat, tongue, and lips
  • Anxiety attacks
  • Digestive issues like diarrhea and vomiting
  • Drop in blood pressure and fainting

If you’re feeling lightheaded or like you may pass out, then you’re likely suffering from a severe allergic reaction and you should seek emergency treatment as soon as possible.

One of the main risks of suffering an allergic reaction is that the anaphylactic shock can constrict your windpipe to the point that your brain can no longer receive oxygen. Keep in mind that this only occurs in the most extreme cases and that many allergic reactions to food aren’t necessarily deadly, so remain calm and seek out treatment.

How to Get Treatment for an Allergic Reaction to Food

If you’ve suddenly realized that caviar or any other food has resulted in an allergic reaction, speak to the people around you and let them know what you’re going through. Don’t get embarrassed and try to solve the issue on your own by going to the bathroom, as this is a surprisingly frequent reaction.

Never drive yourself to the clinic or hospital if you realize that you’re suffering from an allergic reaction. If the symptoms take a sudden turn for the worst, then you may end up crashing into someone else or possibly injuring yourself further, so always call an ambulance to get you treatment.

Cross-Reactivity Between Seafood

When two different food groups give you an allergic reaction, that’s known as cross-reactivity. This is often because the food groups feature similar allergens that can trigger a reaction, and this is why many people who have a shellfish allergy won’t eat fish, and vice versa.

When food allergies can have such a major effect on your health, it’s often a good idea to be careful and avoid even related foods that can result in an allergic reaction.

Another thing to consider is that cross-reactivity can show up later on in life, as well. If you haven’t eaten a certain type of seafood in a long time, it’s possible that your body has developed an allergy in those years, and you may be surprised to be reacting badly to a food that was once perfectly safe for you to eat.
