RESEARCH FOR ANIMAL HEALTH Dear Reader For more than 100 years the Friedrich-Loeer-Institut (FLI) has conducted research in the field of animal health. Over this time period scientific communication has undergone considerable changes. Not only has it left the ivory tower and moved to the heart of society. The speed at which scientific results are commu- nicated and publicized also has steadily increased. At the same time, the interest of society in scientific issues has grown and with it our responsibility as a federal research institute to communicate comprehensibly what we are doing and what we are able to do, and to explain complex scientific contexts and their background. This can be done by publications, media contribu- tions, and in a public dialogue. At the FLI, 850 sta members conduct research for the health To generate scientific data, assess risks, and communicate results and well-being of food-producing animals. However, research on objectively and transparently, is only one of our tasks.
