Pasteurised Milk (Consigned in Sealed Churns).
Forty-six samples of pasteurised milk consigned in sealed
churns to Institutions within this Borough were submitted for
examination.
All conformed to the required standard.
In two samples bacillus coli was present in 1/10 cc.
The method of obtaining samples from sealed churns for
bacteriological examination is still carried out by the process of
vigorously shaking the contents of the churns for a period of two
minutes prior to the sample being taken.
Pasteurised Milk (Contained in Sealed Bottles).
Three samples of pasteurised milk, supplied in sealed bottles,
were examined and found to comply with the bacteriological
standard.
Milk (Not Designated).
Seven samples of milk, not designated, were submitted for
bacteriological examination.
Five were supplied in sealed bottles and two were taken from
10-quart hand cans.
In every instance the bacterial count was much below the
maximum bacterial standard required for pasteurised milk.
Bacillus coli was present in 1/10 cc. (but not in 1/100 cc.), in
one of the samples obtained from a hand can, and was present in
1/100 cc. in one of the samples taken from a sealed bottle.
Milk (Designated and Ordinary) (Examination for Tubercle
Bacilli).
Four designated milks were examined by means of the
"Animal Test" for the presence of tubercle.
Two "Raw" milk samples were similarly examined.
Sample "B" was taken from a large counter pan containing
mixed milk from cows, stalled at the premises where the sample
was obtained, and sample "D" was also taken from a counter pan
containing milk supplied to the dairyman by a farmer direct.
In no instance was tubercle found.
