Abstract
The risks of uncontrolled dissemination of GMOs has made it clear that biosafety is a very relevant matter that goes beyond the State boundaries. This approach has had its corresponding reflection at the policy level, which reveals that the public powers and the legislators have been sensitive to this existing preoccupation in ever-growing sectors of society. From the European regulations, one can deduce a set of principles, which must guide the decisions of the public powers in matters related to biosafety: precaution, authorisation and inspection, “step by step”, “case by case”, traceability and transparency, among other.
