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-amylase test, are carried out.
374 samples of pasteurised home produced liquid egg were taken from the
plants for alpha-amylase test, the results of which were satisfactory, and, of
the imported frozen whole egg examined during the year, only 0.005% failed
the test.
