EPA officers have a role to ensure that we do not become a vector of disease when visiting farms. Officers should not only take precautions against the spread of diseases, but they should be seen to do so.This procedure establishes the routine actions EPA staff need to undertake to minimise the risk of transmitting animal diseases from livestock or poultry farms. The procedure includes biosecurity measures for general farms, as well as industry-specific considerations for piggeries, feedlots, poultry sites (broilers, breeders and hatcheries, egg farms and pullet farms) and dairies.
