 <\/p>\n

Deoxinivalenol, zearalenona, fumosinas son micotoxinas principales reguladas a trav\u00e9s del Reglamento Europeo 1881\/2006 y sus enmiendas.
\nEstudios recientes de la EFSA han presentado otros derivados de estas mol\u00e9culas: micotoxinas modificadas.<\/p>\n

Estas micotoxinas “modificadas” se encuentran como resultado de una reacci\u00f3n defensiva de la planta despu\u00e9s de la infecci\u00f3n o son producidas por el mismo hongo. Se llaman “enmascarados” cuando provienen del metabolismo
\nde la planta.<\/p>\n

Las principales formas ocultas:
\n– DON: 3-acetil-DON (3-Ac-DON), 15-acetil-DON (15-Ac-DON) y DON-3-gluc\u00f3sido en semillas y cereales.
\n– fumosinas: HFB1 en ma\u00edz
\n– zearalenona: alfa-zearalenol, beta-zearalenol, zearalanol-alfa, beta-zearalanol, zearalanona y ZEA-14-gluc\u00f3sido en las semillas y cereales.<\/p>\n

Los primeros resultados de los estudios de EFSA han demostrado que las formas modificadas de micotoxinas tienen la misma toxicidad que sus “padres”.
\nLos alimentos vegetales son m\u00e1s susceptibles a la contaminaci\u00f3n por estos metabolitos. Para productos de origen animal, no hay datos, pero su aparici\u00f3n debe ser baja.
\nEl impacto de estas micotoxinas “modificadas” y “enmascaradas” en la salud a\u00fan es poco conocido.<\/p>\n

Actualmente no existe un proyecto de reglamento, pero se est\u00e1 llevando a cabo un proceso de evaluaci\u00f3n con la recopilaci\u00f3n de datos.<\/p>\n
