Biocides that are released into the environment can have unintended negative environmental effects. The aim of this project was to analyse the current agricultural practice related to the use of disinfectants (PT 03) and insecticides (PT 18) in animal husbandry. Based on the results, recommendations for the application of biocidal products in livestock farming were developed to minimise possible releases into the environment. The long-term objective of the measures is to ensure a holistic hygiene management in livestock farming, including cleaning, disinfection and preventive measures against arthropods, while at the same time ensuring a high level of safety for both the environment and animal health.
