order declaring the premises as infected with Swine Fever not
having been withdrawn during 1929, the premises are still declared
as infected with Swine Fever.
Towards the end of the year, on account of the prevalence of
the disease in the County of Essex, the Ministry of Agriculture
and Fisheries extended the infected area of part of Essex so as to
include the whole of the County of Essex. An order was made on
the 2nd December extending to other parts of Essex, including
Ilford, the Essex and Hertfordshire Swine Fever Infected Area
Order of 1929, placing stringent restrictions on the movement of
pigs.
One movement licence for the removal of swine for slaughter
was issued during the year under the Order. The full effect of the
restrictions not having effect until after the end of the year, this
will be dealt with in the next Report.
Tuberculosis.—During the year, five cows (two in milk) at
the farm attached to a public Institution were reported as suspected

suffering from Advanced Tuberculosis, and in the other two cases
the cows had a chronic cough and showed definite clinical signs
of Tuberculosis. All the cows were slaughtered.
