Many pathogenic agents (e.g. salmonella, swine fever virus, etc.) are carried by rats and mice to people and livestock. It is for that reason that rodents are not only to be viewed as material pests and stock pests but they are of great hygiene significance in modern animal and foodstuff production. Within the scope of increasing hygiene requirements in foodstuff, alongside the general hygiene management at agricultural operations, traceable rodent control has become obligatory.
