Held in one of the Eurofins Biopharma Product Testing laboratory near Paris, the biosafety workshop was successfully conducted by Dr. Arnaud Carlotti. It brought together several French pharmaceutical, biopharmaceutical and medical device companies, which discussed different aspects of biosafety: on one hand PCR, RT-PCR principle and results interpretation; on the other application cases such as fungal and bacterial DNA detection after sterility. Some regulatory matters were also pointed out by the experts and participants. This small working group allowed everyone to share their own issues and experience. Due to positive feedback and interest, a similar workshop will be organised next year with a dedicated part on regulation.
