Frozen Kangaroo Meat
Information was received from another authority that a consignment of
Frozen Kangaroo meat was being despatched to a cold store in this borough.
The consignment had been bought as fit for human consumption but sampling
by this authority showed Salmonella contamination as follows:—
No. of Samples
Salmonella adelaide 1
Salmonella anatum 2
Salmonella Chester 16
Salmonella eastbourne 1
Salmonella muenchen 2
Salmonella onderstepoort 1
Salmonella oranienburg 1
Salmonella typhi-murium 4
The consignment was accordingly detained and subsequently released for
sterilisation for animal feeding purposes only.
Frozen Chicken Meat
Samples taken of Frozen Boneless Chicken meat were found to have high
bacteriological plate counts. Appropriate action was taken with the producer
in Holland and subsequent samples taken by this authority were found to be
satisfactory.
The Liquid Egg (Pasteurisation) Regulations 1963
There are three egg pasteurising plants operating in the Borough, all 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. Two of the plants have long been used for egg breaking and the
third formed part of a new installation in premises specially converted for this
purpose when the Regulations were in draft form. 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 a-amylase test.
One hundred and twenty-one samples of pasteurised home produced liquid
egg were taken from the plants for a-amylase test, the results of which were
satisfactory. The three firms arrange for regular morning and evening sampling
of the production and the results of the analyses are inspected regularly by the
public health inspectors.
No particular difficulties were met with during the second year of the
operation of the Regulations. The home production appeared to be quite satisfactory
and only 1.5 per cent of the imported frozen whole egg failed the
a-amylase test. Apart from 5 tons of Australian egg which was repasteurised in
this country, the remainder was returned to the countries of origin.
