Nanotecnología en la cadena alimentaria

La Agencia Federal de Bélgica para la Seguridad en la Cadena Alimentaria organizará el próximo día 24 de noviembre en Bruselas un simposio internacional sobre nanotecnología en la cadena alimentaria. Este evento se engloba en el marco de la Presidencia belga del Consejo de la Unión Europea y su objetivo es presentar la situación actual de las aplicaciones, oportunidades y riesgos de la nanotecnología en la cadena alimentaria (“de la granja al plato”), mostrando las lagunas en el conocimiento, la legislación y el control. El simposio va dirigido a científicos, fabricantes, reguladores y representantes de la industria, proporcionando numerosas oportunidades para la interacción y el intercambio de conocimientos entre las distintas partes interesadas.

Main questions to be answered:

- What is the consumers’ viewpoint on the promises, potential problems, and wider implications of nanofood for the individual and for society?- Where are the ethical borderlines?

G. GASKELL (London School of Economics, UK)
 

16:05 Theme 6: Regulatory aspects
Items to be addressed:

- International – European – national level- Legislation regarding the food chain (REACH, labelling, etc.)- Regulatory challenges of nanotechnologies- International standards (?)- Official controls (?)

Main questions to be answered:

- Are nano-applications in the food chain covered by the current legislation?- What are the lacunas in legislation?- Is there a need for a specific “nano-legislation”?- Are there any barriers in legislation?- How to control nano-applications in the food chain?- Quid labelling?
