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 for B. Coli and plate count, in addition to the alpha-anylase test, are carried out.
374 samples of pasteurised home produced liquid egg were taken from the plants for alphaamylase
test, the results of which were satisfactory, and, of the imported frozen whole egg examined
during the year, only 0.005% failed the test.
