Eggs

Eggs es la entrada 3 de las catorce sustancias que el anexo II del Reglamento (UE) n.º 1169/2011 hace declarables. IgE-mediated food allergy. Dónde se esconde, qué exenciones aplican y con qué reacciona de forma cruzada.

Esto es información de referencia, no un diagnóstico ni un plan de tratamiento. Un calendario de polen no puede decirle a qué es alérgico, y ninguna página puede declarar un alimento seguro para usted — solo la etiqueta del paquete en la mano y el clínico que conoce su historia. Cualquier cosa más allá de síntomas leves y de corta duración en boca o nariz — hinchazón que afecta la respiración o la deglución, urticaria lejos de la boca, sibilancias, vómito o desmayo — es una pregunta de emergencia, no de lectura.

Qué dice la ley

Anexo II, entrada3: “Eggs and products thereof”

Esa redacción lleva toda la obligación. La sustancia debe declararse siempre que se use en la elaboración de un alimento y siga presente en el producto acabado, incluso en forma alterada, y debe destacarse en la lista de ingredientes por tipografía — negrita, mayúsculas, cursiva, subrayado o un color contrastado. No hay requisito legal de un recuadro de alérgenos aparte, así que la lista de ingredientes es donde mirar.

Qué es realmente la reacción

Egg allergy is one of the two most common food allergies in early childhood. The main allergens are in the white: ovomucoid, ovalbumin, ovotransferrin and lysozyme. Ovomucoid is the one that matters most for what a family can actually eat, because it survives heat while the others do not.

Who gets it, and does it last

Most children outgrow egg allergy, often during the school years, and the usual first step back is baked egg — egg cooked thoroughly inside a cake or biscuit, where the heat-labile proteins are destroyed. Many children who react to scrambled egg tolerate a muffin. That progression is done under clinical supervision, never as a home experiment.

Where it hides

• Mayonnaise, aioli, remoulade and Caesar dressing
• Meringue, mousse, custard and ice cream
• Fresh pasta and many noodles
• Glazed bread and pastry (egg wash)
• Meatballs, fish cakes and pâté as a binder
• Some wines and juices clarified with egg albumin
• Marshmallow and nougat

Every Baltic and Nordic celebration table carries mayonnaise-bound salads, and egg wash is standard on the bread and pastry of the region. Restaurant sauces built on hollandaise or aioli are the routine hidden source.

Cross-reactions

Hen, duck, goose and quail eggs cross-react heavily, so a duck egg is not a substitute. Bird-egg syndrome runs the other way: sensitisation to bird serum albumin from keeping birds can produce reactions to egg yolk and poultry meat.

The labelling detail

Egg is entry 3 with no exemptions. It must be declared even where it appears as a processing aid that ends up in the food, such as albumin used to clarify a wine, and it must be emphasised in the ingredient list.

Exemptions: none. Entry 3 has no carve-outs at all, so there is no processed fraction of it that escapes the label.

Precautionary wording — “may contain”, “made in a factory that also handles” — is a separate matter: it is voluntary, unstandardised and carries no threshold. How strictly to treat it is a clinical decision, not a reading of the label. The labelling explainer sets out the whole frame, including what happens in restaurants and bakeries where there is no pack at all.

Qué se lee mal

The influenza vaccines used in Europe are grown in eggs, and this used to mean automatic exclusion. Current guidance in most European countries is far less restrictive, and the decision belongs with the clinician giving the vaccine — not with a food label.
