Abstract
A case-control study of the factors associated with
the risk of a bovine tuberculosis (TB) breakdown
in cattle herds was undertaken within the randomized
badger culling trial (RBCT). TB breakdowns
occurring prior to the 2001 foot-andmouth
disease epidemic in three RBCT triplets
were eligible to be cases; controls were selected
from the same RBCT area. Data from 151 case
farms and 117 control farms were analysed using
logistic regression. The strongest factors associated
with an increased TB risk were movement of
cattle onto the farm from markets or farm sales,
operating a farm over multiple premises and the
use of either covered yard or 'other' housing
types. Spreading artificial fertilizers or farmyard
manure on grazing land were both associated with
decreased risk. These first case-control results
from the RBCT will be followed by similar
