Farmed deer are any deer that are kept for business purposes. Legislation requires farmed deer to be identified if they are to be tested for TB or leave the farm of origin.

Under the Tuberculosis (Deer and Camelid) (England) Order 2014, suspicion of TB in live farmed or park deer (or any deer carcass including wild deer), must be notified to the local APHA Office.
