GMOs are organisms or microorganisms whose DNA has been altered in a way that does not occur naturally. Since 1997, European Union legislation has required that foods containing GMOs be labeled accordingly. This regulation also applies to products derived from GMOs, even if they no longer contain genetically modified organisms, as long as they contain traces of modified DNA or proteins. In 2003, new regulations were adopted to ensure the traceability of GMOs throughout the food chain. These regulations recognize the possibility of unintentional or unavoidable traces of GMOs in products, tolerating levels below 0.9% without a labeling requirement. Manufacturers are required to inform consumers if their products contain GMOs and to provide unique codes for each GMO used. A specific label must be affixed to products containing GMOs to ensure transparent information for consumers.
