The Liquid Egg (Pasteurisation) Regulations, 1963
There are two egg pasteurising plants operating in the horaugh 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.
338 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 sixth year of the operation of
the Regulations. The home production appeared to-be quite satisfactory and only 0.84%
of the imported frozen whole egg failed the alpha-amylase test.
