EFSA was requested to assess the safety of a broad range of biological agents in the co ntext of notifications for market authorisation as sources of food and feed additives, enzymes and plant protection products. The qualified presumption of safety （QPS� assessment was developed to provide a harmo nised generic pre-assessment to support safety risk assessments performed by EFSA's Scientific Panels.
