SUMMARY OF THE REPORT OF
Messrs. A. H. MUTER, F.I.C., F.C.S.,
and C. H. HACKMAN, F.I.C.,
Public Analysts.
2,000 samples were submitted by the Food and Drugs
Inspector for analysis, 1,000 having been taken with the necessary
legal formalities and 1,000 being informal samples.
Only eight samples were found to be adulterated—two formal
and six informal. The adulteration amounted to .2 per cent.
of the formal, .6 per cent. of the informal samples and .4 per cent.
of all samples, figures on which the Borough can be congratulated.
The 1,000 formal samples were all samples of milk. The two
found to be adulterated were 14 per cent. and 27 per cent. respectively
deficient in fat.
The informal samples submitted consisted of 32 of milk,
882 other foodstuffs and 86 drugs. The following six were found
to be adulterated:—
Milk 3% extraneous water.
Milk 2% deficient in fat.
Tinned spinach Contained zinc.
Bicarbonate of soda Contained excess of lead
Tartaric acid 40% cream of tartar.
Tartaric acid 43% cream of tartar.

The average composition of the 1,028 samples of milk returned as genuine was:—

Total milk solids12.44%
Milk fat3.62%
Non-fatty solids8.82%

Of the 54 samples of cream, 13 were submitted as "half
price," "economy," etc.; their average fat content was 23.3
per cent. The remaining 41 samples contained an average of
53 per cent. fat.
The average fat content of four samples of tinned cream
was 22.7 per cent.
The average water content of the 91 samples of butter
amounted to 14.9 per cent. and in the 48 samples of margarine
to 14.8 per cent.
