One of the main obstacles faced by coeliacs is cross-contamination. This occurs when small amounts of gluten are transferred from one food to another, putting the health of those who must avoid this protein at risk. In this blog, Here's a breakdown of gluten cross-contamination and how you can avoid it, something that is fundamental for following a gluten-free diet correctly.
Gluten cross-contamination is when a gluten-free food comes into contact with gluten or gluten-containing foods.
Cross-contamination of gluten occurs when gluten-free foods come into contact with the protein, either directly or indirectly. This it can happen during food preparation, in the kitchen, on shared cooking utensils, or even in surfaces such as tables and cutting boards. Even small amounts of gluten can trigger an immune response in people with gluten sensitivity or coeliac disease.
Las fuentes más comunes de contaminación cruzada son: * **Manos:** Las manos pueden transferir patógenos desde superficies contaminadas a los alimentos, o de un alimento crudo a uno cocido. * **Superficies de trabajo:** Las tablas de cortar, encimeras y utensilios pueden albergar bacterias de alimentos crudos y transferirlas a alimentos listos para comer. * **Equipamiento de cocina:** Los cuchillos, tenedores, espátulas y otros utensilios de cocina pueden contaminarse fácilmente. * **Alimentos crudos:** Especialmente carnes crudas, aves, mariscos y huevos, pueden contener bacterias que se propagan a otros alimentos. * **Control de plagas:** Los insectos y roedores pueden transportar y propagar bacterias y otros patógenos. * **Ingredientes:** Los ingredientes que no se manipulan o almacenan adecuadamente pueden contaminarse. * **Reutilización de agua:** El agua que se ha utilizado para lavar alimentos crudos (por ejemplo, verduras) no debe usarse para otros fines sin tratamiento. * **Alérgenos:** Aunque no son patógenos, los alérgenos (como frutos secos, gluten, lácteos) pueden causar reacciones graves y su transferencia a alimentos que no los contienen se considera también contaminación cruzada.
