Ice Cream.
Thirty premises were on the register at the end of the year for the manufacture,
storage or sale of ice cream. Legal proceedings were taken in two
instances during the year, one for manufacturing and storing ice cream on
unregistered premises, and one for storing ice cream on unregistered premises
and failing to take steps to prevent contamination. (See table of Legal
Proceedings).
Bacteriological Examination of Ice Cream.
Fourteen samples of ice cream were submitted for bacteriological examination.
Nine of these were found to be unsatisfactory. Letters of warning were
sent to the vendors.
