Yards
Treat sheep for worms on arrival and yard on concrete for 48 hours after worming treatments have
been given. This will avoid contamination of the farm with resistant worm eggs. If only one or two
sheep require yarding a trailer can make a suitable alternative.
Fields & paddocks
Following yarding sheep should preferably be turned out onto ‘dirty’ pasture which has been
grazed by other sheep within the last six months. This dilutes the eggs of any resistant worms
which may have survived quarantine treatment. Animals kept in quarantine fields should not
have direct contact with other stock. If stock must be grazed next to a quarantine field’s boundaries
there should be a double fence leaving a three metre gap between isolated stock and other
livestock. Incoming sheep should be placed on low fluke risk fields (well drained and away
from host snail habitat) for 30 days following a quarantine fluke treatment.
Buildings
If quarantined stock are to be kept in indoors leave a three metre gap between isolated stock and
any other livestock in the building. Ensure that water, feed, bedding, urine and faeces from
quarantined animals does not come into contact with other livestock.
Shared facilities
Where there is a risk of scab from quarantined sheep leave a period of 18 days before using
handling facilities, fields and buildings again with potentially susceptible sheep. Other diseases
will require a much longer waiting period and specific advice should be sought from your vet.
