stores, and 7 from restaurants; 7 are retailers in a small way with rounds,
while 34 sell sterilised bottled milk only, 13 sell sterilised milk and also milk
in sealed containers, and 68 retail milk in sealed containers only. In 3 premises,
pasteurising plant has been installed. Only 2 of these have, however, been

(ii) Licences were granted under the Milk (Special Designations) Regulations,
1936 to 1946, during 1947 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 1947.
(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registered purveyors quarterly and repealed after unsatisfactory results.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.
I he 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.
