SAMPLING OF EGG PRODUCTS, 1961
Sampling of egg products to determine possible contamination
by Salmonella organisms was continued during 1961. In order to
obtain a punctual examination and rapid decision, the importers
paid for a considerable number of samples to be examined. These
results, like all others, were submitted for my approval in the first
instance.
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 and laboratory
results showed that 4.5% of the samples taken from these consignments
contained Salmonellae.
