"Samples 25 and 26 taken from cowsheds and sample No. 27 taken from a shop
were bacteriologically examined, the cultures being made at mid-day immediately
on receipt of the specimens from the Inspectors, and the following results were
obtained:—
Sample No. 25.—(Cow Shed). Coliform bacilli (not B.C.C.), 1,000 per c.c.
Streptococci, 10 million per c.c.
„ No. 26.—(Cow Shed). Coliform bacilli (not B.C.C.), 1,000 per c.c.
Streptococci, 1 million per c.c. Other bacteria, 1,000
millions per c.c.
„ No. 27.—(Shop). B. coli, 1 million per c.c. Streptococci, 10 millions
per c.c.
"The number of bacteria found in these samples of milk appears to me to be
very greatly in excess of the bacteria which should be allowed to be present in a
healthy milk supply. It is very grossly in excess of that allowed in other countries.
In the Public Health Report for the City of Toronto, the bacteriological content
of the milk was investigated, and the number of bacteria allowed in the milk was
placed at a figure very inferior to the number present in these samples. The
improvement in the bacteriological content of the milk of this city was associated
wit 4 a very definite improvement in the figures of the infant mortality. The
bacterial content of the few samples examined here may be compared with the
figures of the Fourth Report of the Royal Sewage Commission of 1904. In samples
taken from the sludge at Barrow Deep, the number of bacteria varied from one
million to 10,000 million per c.c., so that the bacteriological content of some of
these milk samples can be quite justly compared with the bacteriological content of
the Thames sewage.
"The actual bacteria present in these samples comprise not only the lactic acid
bacilli, but coliform bacilli and streptococci in very large numbers. The pathogenicity
of some of these bacteria is shown by the pathological conditions, other
than tuberculosis, set up in the guinea pigs."
