The majority of the results show that these designated milks had a very low bacterial content.
Indeed, only three showed counts in excess of those laid down in the Order. The council have
for some years taken firm action with a view to securing a high degree of purity in designated milks,
and it is gratifying to note that the improvement shown in the results for 1933 was maintained in
1934.
Public Health (Meat) Regulations, 1924.—These regulations provide that no person may slaughter
any animal without first giving verbal or written notice to the council of his intention. Upon
receipt of such notice, the council's food inspector attends during the slaughtering process whether
by day or night, and examines all carcases immediately afterwards. During the year 86 slaughterhouse
inspections were made.
During 1934, nine beasts and 351 sheep were slaughtered in the borough.
