Pasteurised Egg
The Liquid Egg (Pasteurisation) Regulations 1963 came into force on 1st
January, 1964; they require that all liquid egg used for food must be pasteurised
by being retained at a temperature not lower than 148°F. for at least 2\ minutes,
and immediately thereafter cooled to a temperature below 38°F.
In March a large bakery company in the Borough commenced pasteurisation
of liquid egg which had been imported into this country. Frequent inspections
were made to ascertain that the required temperatures were being maintained.
The plant ceased to operate in June. The fourteen samples of liquid egg taken
during the period of operation were all found to be satisfactory.
Milk Supplies
There are two large milk processing depots situated in the Borough, each
with its own private railway siding enabling them to receive milk by rail and
road from the country.
