This is a theoretical-conceptual study that aims to analyse the limitations of the concept of biosafety in light of post-normal science. It intends to contribute to the discussion about the controversies that are associated with biosafety. The presupposition is that the notion of biosafety relies on a technicist approach to risk that does not answer properly the current questions. As the main purpose of biosafety is to protect health and the environment, it is necessary to replace the reductionist perspective of traditional science, in which the notion of biosafety was conceived, by a wide approach: post-normal science. This perspective emphasizes the notions of uncertainty, complexity and quality and takes into account the plurality of social actors and interests involved in the complex environmental and health problems. The study concludes that understanding the concept of biosafety in light of post-normal science implies a fundamental modification, mainly regarding collective health: the substitution of a technicist omnipotent discourse for a dialogue between the different social actors involved in the environmental and health questions.
