If a suspect non-vaccine strain Salmonella Enteritidis (SE) or Salmonella Typhimurium
(ST) is detected in an operator sample you will be immediately informed. Arrangements
will be made for the collection (without charge) of an offical confrimatory sample
by the government inspector and tested by the VLA. If this is negative then no further
action is taken.
If this official confirmatory sample is positive for non-vaccine strain SE or ST
then eggs from the affected flock cannot be sold as Class A. The eggs will be placed
under restriction immediately after you are notified of a positive result.
A government veterinarian may visit your holding to provide advice on Salmonella
control. At a later date, official sample will be collected from all other flocks
on your holding to confirm that the infection has not spread. A further official
sample will be collected when a replacement flock is placed in a house in which
the previous flock was infected with SE or ST. These samples will not be charged
If only the dust sample is positive then fortnightly repeat faecal sampling will
be carried out. This sampling will be carried out on up to four occasions and if
all these samples return a negative result, the flock will be considered negative
for salmonella, official sampling will cease and the routine operator sampling every
15 weeks will continue as normal. Restrictions will not be placed on the eggs from
the flock unless one of these boot swabs or faeces samples is found to be positive
for SE or ST.
