African swine fever (ASF), avian flu, avian influenza, foot-and-mouth disease and mastitis are familiar to every farmer. These are common diseases in the livestock sector. If such an epidemic breaks out on a farm, this can have considerable consequences for the livestock farmer. In addition, diseases that are passed on from animals to humans cannot be ruled out. Listeria and salmonella are examples of this. In animal husbandry, the risk of pathogens must be contained by hygiene measures such as disinfection, protective clothing and pest control.
