Veterinary hygiene service

The unit has an organised veterinary hygiene service, where, in the area it covers, it removes dead animals and takes them to the cadaver collection and takes care of their harmless destruction. This service is of the utmost importance as removal of carcasses removes sources of potential infection from the point of view of preventing the spread of the disease to both animals and humans. It is also important from the point of view of protecting the environment because removing animal carcasses helps prevent pollution of water, soil and feed.
