plates a few colonies of B. Coli were isolated. The gelatine plates were rapidly
liquified with the lower dilutions, but the liquified gelatine had not an unpleasant
odour. The anaerobic cultures failed to shew the presence of Klein's bacillus.
The centrifugalised deposits showed a few bacteria, milk globules, and starch
granules. No gross impurity was seen.
The guinea-pig inoculated shewed no symptoms, and remained alive and well.
Sample II. did not differ much from sample I. The number of bacteria on
gelatine plates being about 10,000 per cubic centimetre.
The liquifaction of the plates was not of an unpleasant odour.
No bacillus enteriditis sporogenes was found. An inoculated guinea pig remained
well.
Sample III. was not so good as samples I. and II. The number of bacteria was
about 45,000 per cubic centimetre. Several of these were B.Coli. The liquified
plates had an unpleasant odour. No bacillus enteriditis sporogenes was found, and
an inoculated guinea pig remained healthy and well
Dr. Bulloch states that the general results of these examinations would go to shew
that the ice creams were of much greater purity than many that have been examined
in recent years, and although 10,000 bacteria may seem a large number, it is really not
so serious when one considers that relatively few of these were capable of growing at
37° Cent. i.e. body temperature. From a study of these results Dr. Bulloch was of
opinion that the ices submitted to him were relatively pure, and he did not consider
that the consumption of such samples could endanger health.
The following is a brief summary of the inspection of the ice cream shops made
during the course of the year. Ten were visited by inspector Lear. Of these, five
were in a satisfactory sanitary condition; in four, more or less cleansing was
necessary : and in the remaining one, defects in connection with the drainage system
required rectification. In four visited by inspector Quelch, insanitary conditions
required dealing with in each one. Of thirteen visited by inspector Firth, six were
found in a clean and sanitary condition. In the remaining seven, insanitary conditions
were found to exist. In three ol these the water-closets were in such close proximity
to where the ice cream was being prepared as to be distinctly dangerous, and in one
case it was discovered that the copper used in the preparation of the cream was
utilised for the boiling of dirty underclothing in. Inspector Jordan visited sixteen.
Twelve of these were in a satisfactory sanitary condition, and in the remainder, want
of proper attention to cleanliness was observed. Inspector Langstone visited twenty.
In five of these insanitary conditions, mainly resulting from want of proper attention to
cleanliness, existed, and in one instance it was found that the cream was being
manufactured in a room used for living and sleeping in.
