Egg is a popular food and ingredient. Unfortunately, this versatile and nutritious food is also one of the Top 8 Allergens. Egg Allergy is a serious condition, but with education and planning, it is possible to eat a healthy and enjoyable diet.
Keep reading for more information about this common allergy. This article will help you understand risk factors, avoiding eggs, getting help from healthcare providers, and planning a safe diet.

Risk Factors
Risk factors for egg allergy include history of atopic dermatitis and family history of food allergies. Egg allergy is more common in children than in adults. Other factors may include genetics, environment, epigenetics, sex, ethnicity, nutritional status, inflammation, and dietary history (source).

Avoiding Eggs
When you can’t eat eggs for safety reasons, avoiding eggs and egg products is more complex than simply avoiding eggs at breakfast. Eggs are used as an ingredient in many foods and medical products.
Common Forms of Egg

- Cooked Eggs
- Dried Eggs
- Egg Wash
- Egg White
- Egg Yolk
- Fried Eggs
- Liquid Eggs / Cholesterol Free Liquid Eggs such as Egg Beaters

How Eggs Are Used in Cooking
Many foods have eggs as a hidden ingredient. It is helpful to think about what eggs do and how they are used.
- As a Binder – This holds water and other food ingredients together.
- As an Aerator – Eggs add to the structure of baked goods and hold air in small pockets.
- As an Emulsifier – This prevents oil and water from separating from each other.

How to Read a Label for Egg
Since eggs are one of the major eight allergens, it is required by federal law that manufacturers list it in plain language on their packaging (source).
It is important to read food labels and look out for advisory messages that tell you a product may have come in contact with egg.
When in doubt, it is better to play it safe. Even small amounts of egg may trigger an allergic reaction.
Cross-contamination
If you or your child has an egg allergy, there are several strategies you can use to help prevent cross-contamination:
- Wash hands with soap and water when preparing foods to help remove residual egg proteins.
- Wash hands with soap before and after eating.
- Inform staff at restaurants or other venues about your food allergies so that precautions can be taken to avoid any contact with egg or any foods that contain egg.
- Set up your kitchen at home so that cross-contamination is avoided. If other people in the house eat eggs or foods made with egg, you may designate specific areas of the refrigerator, freezer or pantry as “egg-free” and / or “egg” areas.
Medications and Vaccines
Eggs and egg ingredients are used in the manufacture of some medical products. These may be contraindicated in the case of egg allergy, or they may be able to be used with additional precautions.
Always inform your healthcare providers about your egg allergy and ensure that it is documented in your medical record. Also, be sure to discuss these and any new medication with your health care team.
Vaccinations
Vaccines are shots that help prevent illness. Some contain egg proteins. In some people, these vaccines pose a risk of triggering an allergic reaction. Sometimes additional safety measures are needed in order to receive these vaccines.
Flu Shot
Some flu vaccines contain a small amount of egg protein (source). Some versions of flu vaccines are manufactured without the use of egg components.
The CDC recommends that people with egg allergy and any type of vaccine allergy ensure that their allergies are documented with their healthcare provider.
Vaccines should be received at an inpatient or outpatient setting under the supervision of a health care provider who can identify and handle severe allergic reactions (source).
Be sure to talk to your doctor to determine what is safest for you.
Measles-mumps-rubella (MMR) vaccines
MMR vaccines may be manufactured with the use of egg ingredients. Be sure to discuss egg allergy with your doctor if you need this vaccine (source).
Yellow fever vaccine
Yellow fever vaccine contains some egg proteins and has generally been considered contraindicated for people with egg allergy. However, some protocols have been developed that allow for vaccination in this population (source).
If you have egg allergy and need yellow fever vaccine based on your travel plans or local conditions, it is best to talk to your doctor about this in detail.
Other Vaccines
We recommend talking to your doctor about the risk of allergic reactions to vaccines if you are allergic to egg, vaccines or other substances.
Propofol
Propofol is a medication used in anesthesia. There has been a suspected connection between egg allergy and propofol (source). Propofol contains egg lecithin.
However, research indicates that most allergic reactions to propofol are not related to egg allergy and people with egg allergy did not appear to have adverse reactions to propofol.
Propofol may be safe for people with egg allergy, but it is essential to discuss your allergy history in detail with your healthcare providers and Anesthesiologist.
Total Parenteral Nutrition
Total parenteral nutrition (TPN) is routinely used for patients that have dysfunctional gastrointestinal systems. A nutrition formula is given through a vein which bypasses the digestive tract. Intravenous fat emulsion is an essential part of TPN and contains egg-yolk phospholipids (source).
While being hypersensitive to TPN is rare, it is possible.
A study was done on a pediatric patient that presented adverse reactions to TPN due to egg-yolk phospholipids. The patient was tested for both egg white and egg yolk allergies and tested positive for both (source).
Other Reasons to Avoid Egg
Even when eggs are not a food allergen, people may avoid eggs for other reasons.
Vegans, vegetarians, and pescatarians may avoid eggs for health, religious, or ethical reasons.
Some people may avoid eggs due to digestive discomfort or personal preference.
Sensitivity and Intolerance
Egg intolerance is not usually life-threatening. Intolerance generally refers to an adverse food reaction that is not due to a response in the immune system. Symptoms may include abdominal pain, cramps, diarrhea, nausea, and vomiting.
Egg intolerance is different from an egg allergy.
Intolerance may be identified by observing symptoms after eating eggs, keeping a food journal, and following an elimination diet.
Avoiding eggs is generally the treatment for egg intolerance. Some people may tolerate egg whites but not egg yolks. Some people may tolerate egg yolks but not egg whites.
Sensitivity
Egg sensitivity is not usually life-threatening. Sensitivity generally refers to an adverse food reaction that involves the immune system but is not IgE mediated.
Allergic reactions usually occur quickly after exposure, but an intolerance may provoke symptoms up to three days after exposure.
Eosinophilic Esophagitis
Eosinophilic esophagitis is an adverse immune response to foods. People with this condition experience inflammation and other changes in their esophagus.
Symptoms include difficulty swallowing, difficulty eating, pain, and vomiting.
Eggs and other foods are associated with this condition (source).
Egg-Free Diet
If you avoid eggs due to adverse food reactions or other reasons, it may be helpful to consider the nutrients provided by eggs and consider if you need to identify other sources of these nutrients.
Eggs are a good source of protein as well as choline, lutein, omega-3 fatty acids, selenium, and vitamin D.
Because eggs are an ingredient in so many foods, it may be difficult for some people to eat enough food or eat a variety of foods. The difficulty can be even worse for people with multiple dietary allergies or other dietary restrictions.
People who avoid eating eggs may be at nutritional risk and we recommend working with a healthcare professional to address these risks.

The following foods may be used in place of eggs when eggs are used as a functional ingredient in a recipe.

- Apple Sauce
- Bob’s Mill Gluten Free Egg Replacer

Help is Available
If you suspect you have an egg allergy, it is recommended that you contact your physician or allergist to get an accurate diagnosis. Blood tests and skin prick tests may be needed.
Specialized treatments may be available, including food challenges and oral immunotherapy. These treatments should only be done under medical supervision.
We also recommend talking to your doctor about emergency medications and safety plans.
Working with a Registered Dietitian, Certified Leap Therapist, or Certified Nutrition Specialist can help find foods that you like and can safely eat.
Final Thoughts
Choosing groceries when you have food allergies can be challenging. This is why we recommend choosing groceries made with a single ingredient and focusing on what you CAN eat, not just what you have to avoid.
