The Regulations relating to the manufacture of ice-cream are
contained in the Ice-Cream (Heat Treatment, etc.) Regulations, 1959.
Samples are taken regularly from premises in the Borough where
ice-cream is manufactured and if unsatisfactory results are obtained,
advice is given and the matter followed-up until a satisfactory quality
results.
"Soft" ice-cream, that is ice-cream sold directly from specially
designed freezers, shortly after production, has been on sale for several
years. The introduction of a smaller and more compact freezer has led
to the development of " Soft" ice-cream on sales vehicles. The maintenance
of hygiene on vehicles presents difficulties not met with in
manufacturing premises. A number of shop premises are having these
machines installed and are operated by people who have no previous
experience of ice-cream manufacture or of the cleansing and sterilisation
of the plant used.
The manufacturers give full instructions for the cleansing
sterilisation of the freezers, but it is quite often necessary for the whole
process to be gone over in the presence of a Public Health Inspectorwho
is able to give the necessary advice.
It is essential for regular cleansing of the machine at the end
each day's use and unless this is carried out correctly, it leads to
bacteriological contamination.

that the lacquer of the lid had deteriorated and softened and in places
had become detached from the metal. The manufacturers were duly
informed of this deterioration, for the appropriate steps to be taken.|
