One of the disturbing features in connection with the distribution of milk is the dirty milk
bottle. Invariably the dirty bottle is the result of misuse of the bottle by the public—the bulk of the
dirty bottles contain cement as the result of lying about on building sites, but there are many other
sources of contamination e.g. the use of bottles for paint, for the discharge of fireworks and as
substitute flower vases. When these bottles are returned to the dairies they are subjected to a standard
cleaning process which is most efficient in dealing with the average returned bottle but is incapable
of coping with bottles used as described.
These bottles should be removed in the inspection process but there is a high proportion of
failure in the inspection systems which will only be resolved by reducing the speed of the inspection
cover or by the provision of more efficient electronic scanners which will automatically reject the
unsatisfactory bottle.
Cream

A failure rate of 28% is most unsatisfactory but it is a slight improvement on last year's failure
rate of 36-3%. Inspectors are now able to give more attention to the storage of this type of food and
the position should greatly improve in the future.
Ice Cream
The methylene blue test as applied to ice cream affords a provisional assessment of bacterial
cleanliness of the product. Most of the failures were due to faults in the storage and handling of the
product. The principle fault being failure to properly sterilise the utensils used in the final dispensing
of the ice cream. Details of the samples taken are set out in the following tables:
