Canned Hams
Owing to the fact that a considerable weight of canned hams from
various continental countries were found to be unsound and in view of
the monetary loss involved it was considered desirable to ascertain by
bacteriological examination the possible cause of the unsound condition
of the contents of the cans In some of the samples submitted Cl
Welchii was isolated and generally it was found that the types of
organisms isolated suggested careless handling and insufficient sterilization
at the time of manufacture.
Frozen Foods
Several samples of the various prepacked frozen foods were submitted
and in the majority of cases it was reported that the samples
were free from pathogenic organisms In the case of samples of a
meat product submitted it was not possible to prove definitely the
presence of any contamination or the use of infected material Nevertheless
the results do serve as a warning that very close hygienic and
bacteriological control of these materials should be exercised
Canned Evaporated Milk
As a result of information received from another local authority
samples of a particular brand of canned evaporated milk on sale in the
borough were submitted for examination The report of the bacteriologist
showed that the contents of these tins were not fit for human
consumption and the whole of the stock held by the trader was destroyed
and an appropriate certificate issued
Wines and Spirits
An interesting and unusual case occurred during the year in respect
of a quantity of wines and spirits which had been stored in a cellar
which had been flooded with crude sewage As a result of exhaustive
examinations it was decided that no serious infection by pathogenic
organisms had taken place and after negotiations with the owners some
of the goods were destroyed and the remainder were released for con
sumption.

logical examination is carried out from shops depots roundsmen
