(ii) Licences were granted under the Milk (Special Designations) Regulations,
1936 to 1946, during 1948 for the sale of:—
"Tuberculin Tested" Milk 16
"Pasteurised" Milk 23
The above include supplementary licences which were issued for
"Tuberculin Tested" milk, 7; and "Pasteurised" milk, 8. These are
licences granted to firms who already have a primary licence from another
Authority, the milk being bottled outside the town, but sold in Ilford.
The Essex County Council granted one producer's licence in respect of
graded milk produced on a farm in the Borough during the year 1948.
(iii) Sampling.—The following is the routine practice adopted:—
Designated Milks.—These are sampled bi-monthly and after unsatisfactory
reports.
Ungraded Milks.—Samples of these milks are taken from all
registered purveyors quarterly and repeated after unsatisfactory results.
Biological Tests.—Samples of all milks, designated or otherwise,
are submitted for biological test for T.B. in Spring. Repeat samples
if positive after clearance by County Medical Officer.
Milk Supplies to Elementary Schools.—These are sampled monthly
and after unsatisfactory results.
Ice Cream.—Samples are taken monthly from April to September
and at regular intervals during the winter months from all local manufacturers,
tricycle salesmen and local retailers. Samples are repeated
after unsatisfactory results.
The Heat-Treated Milk (Prescribed Tests) Order, 1944, prescribes two
tests, a phosphatase test for adequate heat-treatment and a methylene blue
test for keeping quality. The Order defines temperatures at which samples
must be kept both before reaching the laboratory and before the test and
stipulates the hours during which the test must be conducted.
