Is it safe to eat eggs? Find out how to avoid the risks associated with its consumption.
Eggs are a staple food in our daily diet. It is economical, versatile, highly nutritious and an excellent source of protein of high biological value. Thanks to these qualities, it forms a fundamental part of the diet in many households and is an essential ingredient in dishes such as omelets, flans, Shakshukas, Scotch eggs or eggs Benedict. However, its consumption and handling require certain care, especially with regard to food safety and the risk of bacterial infections, such as salmonellosis. Below, we share with you the essential keys to enjoy the benefits of eggs safely and without compromising your health.
MAIN RISKS ASSOCIATED WITH EGG CONSUMPTION
Salmonellosis: This is an infection caused by Salmonella bacteria. When contaminated eggs are ingested, the bacteria can adhere to the intestinal walls and multiply, causing symptoms such as fever, diarrhea, abdominal pain and vomiting. Although usually mild, in people with compromised immune systems (such as children, the elderly or people with pre-existing diseases) it can become severe and even fatal.
Egg allergy: Egg allergy is one of the most common food allergies, especially in children. This reaction occurs when the immune system mistakenly identifies egg proteins (especially those in the egg white) as a threat, triggering an immune response. Symptoms can range from mild (hives, eczema, vomiting) to severe (anaphylaxis).
Infections by other pathogens: In addition to Salmonella, eggs can be contaminated with other pathogens such as Campylobacter and Escherichia coli, especially if they are not stored or handled properly.
PREVENTION AND SAFETY: KEYS TO SAFE EGG CONSUMPTION
1. Use pasteurized eggs
For preparations in which the egg is not fully cooked or is consumed raw (as in mayonnaise, tiramisu or steak tartares), it is highly recommended to use pasteurized eggs. Pasteurization consists of subjecting the egg to a controlled temperature that eliminates bacteria such as Salmonella without altering its nutritional properties or flavor. They can be found in liquid or powdered form, and are especially recommended for pregnant women, young children, the elderly and those with weakened immune systems.
2. Do not wash eggs before storage
The question frequently arises as to whether eggs should be washed before storing them in the refrigerator. However, international agencies do not recommend this. Eggs have a natural protective cuticle that prevents the entry of bacteria through their porous shell. When eggs are washed, this barrier is removed, facilitating the entry of microorganisms. If the shell is dirty, it is best to wipe them with a dry cloth just before use and not before storage.
3. Avoid sudden temperature changes
Proper egg preservation is key to prevent bacterial growth. Eggs should always be kept under constant refrigeration, at a temperature below 7 °C, as sudden changes in temperature can cause condensation on the shell, which facilitates the entry of bacteria. So why are they out of the fridge in European supermarkets? In the European Union, for example, eggs are not washed or disinfected before arriving in stores, allowing them to retain their cuticle, a natural layer that protects them from bacteria. However, once purchased, it is advisable, as mentioned above, to store eggs in the refrigerator to ensure freshness and reduce the risk of bacterial growth.
4. Proper cooking
Heat destroys pathogenic bacteria such as Salmonella, so the simplest and most effective method to reduce risks associated with egg consumption is to cook eggs thoroughly. According to FDA and WHO recommendations, eggs should be cooked until both the white and yolk are firm. Dishes containing raw eggs, such as certain sauces or desserts, should be made with pasteurized eggs.
5. Check the freshness and quality of the egg
It is essential to check the freshness of the egg before consuming it. A simple method is to place the egg in a glass of water: if the egg floats, it is best to discard it, as this indicates that it is in poor condition. In addition, checking the expiration date indicated on the package is crucial to ensure that the egg is consumed in optimal conditions.
6. Avoid cross-contamination
If someone at home is allergic to eggs, use separate utensils, dishes and cutting boards for egg and non-egg preparations. Wash utensils and surfaces thoroughly after handling eggs to avoid any accidental contact.
7. Crack the egg in a separate container
Cracking the egg into a small bowl allows you to check if it is in good condition before adding it to the main recipe. This reduces the possibility of contaminating the rest of the ingredients if the egg is in bad condition.
8. Consuming raw egg preparations quickly
In preparations with raw or semi-raw eggs (such as mayonnaise or homemade tiramisu), use pasteurized eggs and consume the product the same day or the next day. Avoid leaving them at room temperature and refrigerate them as soon as possible.
9. Avoid prolonged exposure to heat
Do not leave cooked egg dishes at room temperature for more than two hours, especially in hot climates, to prevent bacterial growth.
10. Disinfect surfaces and hands
Wash hands thoroughly after handling raw eggs to prevent the spread of bacteria. Clean and sanitize surfaces and utensils used to reduce the risk of contamination of other foods.
11. Discard eggs with cracked or dirty shells.
Eggs with broken shells or visible stains can facilitate the entry of bacteria. Be sure to check their integrity before buying and using them.
* Introduction of eggs as a novel food in children
Egg is one of the 9 major allergens. Therefore, when starting complementary feeding, the introduction of this food should be done with extreme caution. Be sure to make a gradual and controlled introduction, always under supervision and avoid serving raw or semi-raw eggs. Always consult your pediatrician before introducing it.
