The Liquid Egg (Pasteurisation) Regulations, 1963
There are two egg 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.
309 samples of pasteurised home produced liquid egg were taken from the plants
for alpha-amylase test, the results of which were satisfactory.
No particular difficulties were met with during the fourth year of the operation
of the Regulations. The home production appeared to be quite satisfactory and only
0-67 per cent of the imported frozen whole egg failed the alpha-amylase test.
