Food and Food Premises
Section 57(1) (a) of this Act requires that it shall not be
lawful:—
for the occupier of any premises to use them as a slaughterhouse
or knacker's yard or permit them to be so used, unless he
holds a licence granted under this section by the local authority
authorising him to keep those premises as a slaughter-house or, as
the case may be, as a knacker's yard.
During the year three applications for the renewal of licences
to use premises as slaughter-houses were submitted to the Council
and granted.
Bacteriological Analysis of lee-Cream
During the year 174 samples of ice-cream were tested in
accordance with the technique suggested by the Ministry of Health
and Public Health Laboratory Service in their Bulletin of March,
1947.
The following table gives a summary of the results:— TABLE XI.
| Methylene Blue Test. | Coliform Test. | ||
|---|---|---|---|
| Provisional Grade | No. of Samples | Coliform in l/10th ml. (non-faecal) | No. of Samples |

Two samples were submitted to the Methylene Blue Test,
which was nullified due to interference of colouring matter.
In addition one sample of ice lollies was examined following
two cases of dysentery. No pathogenic organisms were isolated.
