Milk Licensing and Sampling
One hundred and eighty-one premises are registered for the sale of milk and the
following licences for the sale of graded milk have been issued:-
"Untreated" Milk 40
"Pasteurised" Milk 150
"Sterilized" Milk 108
"Ultra-heat Treated" Milk 74
One hundred and thirty-five samples of raw milk were submitted to the Laboratory
for the screening milk ring test. A positive reaction in one small herd serving a closed
community was followed up and one animal was isolated and eventually sent for slaughter
when biological examination proved the cow to be infected with Brucella abortus. The
results of a further sixteen biological examinations were negative. One sample of untreated
milk was bacteriologically unsatisfactory. Two subsequent samples from the same
source were satisfactory.
Food Complaints
Two hundred and fifty-six complaints were received as to quality, soundness or
the presence of foreign bodies in food. In most cases advice and information was given
with the object of avoiding a further similar incident but in thirty cases the offence
justified formal proceedings. There was an increase of just over 15 per cent in the number
of complaints received during the year but this was not so great an increase as that
reported last year. It is perhaps of interest to note that in nearly l/5th of the cases the
complaint was not substantiated. This is the highest figure ever reported under this category.

The table below classifies the nature of the complaints:

1. Foreign Bodies
(a) Insects40
(b) Metal objects7
(c) Glass, stones, etc.17
(d) Paper, wood, string, etc.6
(e) Oil, grease etc.15
(f) Fabric, plastic, rubber etc.6
(g) Cigarette ends1
(h) Harmless matter, e.g. burnt dough in bread9101
2. Quality
(a) Unsoundness14
(b) Mould growth48
(c) Rancidity, sourness etc.971
