Possible conflicts of interests:
Collaborates with different branches of animal production and biotech industry in different countries including Denmark. This work occationally include externally funded projects. The representatives from the companies are occationally partners in the projects or serve as advisors to the projects. In all these relations I act as an employee of the University of Copenhagen and do not receive any renumeration from the external partners.
I work as scientific expert for EFSA as a menber of the FEEDAP panel ( - 2024) and as member of the FEED microbiology group. I receive a salary for this work from EFSA. My DOI is published at the EFSA website: https://ess.efsa.europa.eu/doi/doiweb/doisearch/panel/FEED/wg/684416
