The Liquid Egg (Pasteurisation) Regulations, 1963
There are two pasteurising plants operating in the Borough both of which combine
the process of egg pasteurisation with that of egg breaking and the freezing of liquid egg;
the plants are high temperature short time with inplace cleaning. Each plant is equipped
with its own laboratory in which tests required by the Egg Marketing Board of those
companies under contract to them are carried out. These tests include B. Coli and plate
count in addition to the alpha-amylase test.
342 samples of pasteurised home produced liquid egg were taken from the plant for
alpha-amylase test, the results of which were satisfactory.
No particular difficulties were met with during the fifth year of the operation of
the Regulations. The home production appeared to be quite satisfactory and only 1.27%
of the imported frozen whole egg failed the alpha-amylase test; this was repasteurised.
