Along with fish, shellfish allergies are the most common adult-onset food allergies. Its estimated that more than 6.5 million American adults have allergies to one or both, according to Food Allergy Research & Education .

There are two kinds of shellfish, crustaceans and mollusks. Here are a few examples of crustaceans to watch out for if youre allergic:

  • shrimp
  • snails
  • scallops

A shellfish allergy is different from other allergies in other ways, as well. For example, allergic reactions to shellfish are unpredictable, sometimes occurring long after a person has consumed the allergen and has shown no other symptoms. Allergic reactions to shellfish also often become more severe with each exposure.

What Are Signs Of Mild Allergic Reaction

Symptoms of a mild allergic reaction vary from person to person. The most common signs include an itchy rash on the body. For contact allergies, the rash is usually localized to the part of the body that touched the substance, but with internal exposure caused by eating or breathing in the trigger the rash can spread across the entire body.

You Dont Have These Symptoms

Colds and allergies share many of the same symptoms, so it can be tough to tell which one youre going through. Because they share symptoms such as coughing and congestion its helpful to consider the symptoms that these two conditions dont share.

  • Fatigue
  • Severe headache
  • Sore throat

The mans family was awarded a $4.7 million settlement for successfully arguing that the contrast iodine used in his treatment for acute coronary syndrome had caused the mans death.

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

For information on foods to avoid, check sites such as the Food Allergy Research and Education network .

Always read food labels to see if a food contains shellfish. Manufacturers of foods sold in the United States must state whether foods contain any of the top eight most common allergens, including crustacean shellfish. The label should list “shellfish” in the ingredient list or say “Contains shellfish” after the list.

Some foods look OK from the ingredient list, but while being made they can come in contact with fish. This is called cross-contamination. Look 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 all 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, shellfish can get into a food product because the staff use the same surfaces, utensils , or oil to prepare both shellfish and other foods.
