THE PUBLIC HEALTH (CONDENSED MILK) REGULATIONS.
During the year eight samples of condensed milk
were submitted for examination. Of this number, three samples
were also examined for the purpose of testing the equivalent.
This test determines whether the contents of the tin will, when
converted, give the amount of milk which is declared on the
label.
CONDENSED FULL-CREAM MILK, SWEETENED.
Five Samples. Two of these were also tested for the equivalent.
CONDENSED MACHINE - SKIMMED MILK,
SWEETENED. Three Samples. One of these was also tested
for the equivalent.
In addition to the above, one tin of evaporated milk was
examined and also tested for the equivalent.
All samples, including the labelling requirements, complied
with the regulations.
STRAWS. Three samples of straws as used by school
children for the drinking of milk were submitted to the pathological
laboratory for examination, and proved to be satisfactory.
