CIHEAM Zaragoza has organised a three part training course for the staff of EFSA´s FEED Unit on risk assessment for feed additives. CIHEAM Zaragoza was selected by EFSA, following a competitive bidding process, to provide the expert training. The course was delivered face-to-face in Parma in December 2019, January 2020 with a final on-line course being provided in February 2021. A subsequent two-day field trip to feed producing facilities will be organised in Spain following Summer 2021. The course has been organised along similar lines of the institute´s well-established training model which engages leading external experts to deliver high-level training on behalf of CIHEAM. The course counted on the participation of over 15 international experts and scientists and covered a wide range of animal species including ruminants, poultry, fish, pets, bees, and snails. The following technical and scientific areas were covered during the course: animal nutrition, animal physiology and production (including feeding techniques, feed formulation, nutrient requirements, etc.), design, conduct and evaluation of feeding trials with food producing animals, pharmacokinetics, pharmacodynamics, metabolism and residue studies and exposure assessment.
