SAMPLING OF EGG PRODUCTS 1959
Sampling of egg products to determine possible contamination
by Salmonella organisms was continued during 1959. In order to
obtain a punctual examination and rapid decision, the importers
paid for a considerable number of samples to be examined.
The method of sampling was by batch numbers (signifying
packing dates and factories). Where a sample showed evidence of
contamination the whole batch was placed under detention and
later either re-exported or released for pasteurisation and high
temperature baking.
The main importations were of frozen whole egg of which the
chief exporters were China, Australia and South Africa and laboratory
results showed that 6.0% of the samples taken from these
consignments contained Salmonellae. The total number of
samples from all egg products found to be contaminated was 222
and the following table shows the type of contamination: —
