average bacterial count of the 14 satisfactory samples was 44,616
per cubic centimetre. The average count of the sample below the
standard was 508,000 bacteria per cubic centimetre.
(6) Coliform Bacilli.—The standard adopted is that coliform
bacilli should not be found in a smaller quantity of milk than onetenth
of a cubic centimetre; in effect this means that there should
not be more than 10 such organisms present in 1 cubic centimetre
of milk. The value of this examination is considered to be very
great as it is a definite indication of excremental contamination.
Of the 15 samples examined, 8, or 53.3 per cent., were found to be
satisfactory.
The condition of the samples as regards coliform bacilli is shown in the following table :—
| Coliform Bacilli. | No. of Samples. | |
|---|---|---|
| Not found in ) c.c. or less | 3 | satisfactory |
| Present in 1 c c. but not in less | - | |
| " " .1 c.c. " " | 5 | |
| " " .01 c.c. " " | 7 unsatisfactory | |
(c) Tubercle Bacilli.—12 samples of milk were examined for
the presence of tubercle bacilli, all of which gave negative results.
(d) Summary.—Of the 15 samples examined, 8, or 53.3 per
cent., were satisfactory in every respect as regards total bacterial
count and bacillus coli content.
2. Designated Milk.
Five samples of Pasteurised Milk sold under licence within
the terms of the Milk (Special Designations) Order, 1923, were
examined. As regards total bacterial count and bacillus coli
content all were satisfactory. The five samples were also examined
for the presence of tubercle bacilli with negative results.
