Eleven per cent, of the samples contained 4 per cent, or more fat. Milk with
this fat content does not appear to be uncommon.
In 16 cases where the fat content subsequently proved to be four per cent.,
from observations made at the time of purchasing, the samples showed that in
10 instances the milk was stirred with a hand measure before serv ing. In one case
a plunger was used and in two other cases where the milk was served at tables in
restaurants plungers are provided and it is probable they were used. In three cases
the milk was served from the hand cans of roundsmen and was probably well mixed.
Tt is probable that even distribution of milk fat is not secured by casual mixing with
hand measures. The use of efficient plungers would secure this end. On the other
hand, where there is reason to believe milk is properly plunged, an analysis has
shown the presence of over four per cent, of fat.
Of the 16 samples referred to above nine were purchased at dairies or milk
shops, two in restaurants and three from street vendors.
