PROTECTION OF FOOD SUPPLY.
Slaughter Houses and Knackers' Yards.
The duty of licensing knackers and slaughterers of cattle and
horses, and the premises used by them, was transferred to the
Metropolitan Borough Councils in 1933.
At the beginning of this century there were nine premises licensed
as slaughterhouses, and the only one now remaining is at No. 345
Battersea Park Road at which only a few animals are slaughtered
from time to time.
There are no knackers' yards in the Borough.
Food and Drugs Act, 1938.
The analysis of samples of food and drugs procured under the
provisions of the above-mentioned Act, or informally (i.e., without
following in detail the procedure prescribed by the Act) is carried
out by the Public Analyst for the Borough, at his laboratory at
325 Kennington Road, S.E.1 1.
The bacteriological examination of samples (mainly milk) is
carried out by the Clinical Research Association, Ltd., at Watergate
House, Strand, W.C.
The total number of food samples taken under the Act during
1947 was 595, of which 3 or 0.5 per cent, were certified by the Public
Analyst to be adulterated. In addition to the foregoing, 605 informal
samples were procured, of which 10 or 1.7 per cent, were reported
against.

adulterated, or not to comply with the requirements of the various
