83 Pork Sausages 67 genuine; 15 contained boric acid:—3.0, 4.9, 6.19,
7.5, 7.9, 9.8, 10, 12.0, 12.39, 14.84,14.87, 16.1, 17.5,
29, 30.8 grains per lb.; 1 contained 2.2 grains
anhydrous sodium sulphite.
8 Beef Sausages 5 genuine; 3 contained boric acid:—7.4, 24.5, 46
grains per lb.
1 Liver Sausage Genuine.
10 Grerman Sausages 6 genuine (1 Strasburg and 1 lunch); 4 contained boric
acid:—4.9, 8.6, 14.8, 24.79 grains per lb.
2 Saveloys 6 genuine; 1 contained boric acid :—9.5 grains per lb.
1 Black Pudding 1 genuine.
23 Pork Pies 11 genuine; 12 contained boric acid:—0.8, 20, 2.1,
3.0, 3.4, 3.5, 3.7, 5.0, 5.0, 5.5, 6.5, 7.0 grains
per lb. (crust included).
35 Meat Pies 29 genuine; 6 contained boric acid:—3.18, 5.19, 5.9,
6.0, 7.0, 7.5 grains per lb. (crust included).
3 Sausage Rolls 2 genuine; 1 contained 1.5 grains boric acid.
3 Brawn 2 genuine; 1 contained 9.17 grains boric acid.
In reporting upon the pies the analysts stated the amount of boric
acid found in the pie as a whole but in certain instances particulars
were given showing the amount found in the pie apart from the crust.
In 4 pork pies the amount in the meat portion was 5.95, 9.17, 13.86
and 14.87, including the crust the same pies gave only 2.0, 3.7, 3.4 and
5.5 grains; in 3 meat pies the amount without crust was 12.39, 15.9,
16.1, with crust 5.1, 5.9, 7.5 grains.
In these various meat preparations there has been a decided
reduction in the amount of boric acid used as compared with previous
years. The season of the year does not appear to make any difference
in the amount of preservative used.
Tinned Fish and Meat.—Except a small quantity of preservative in
a lobster paste, various potted meats and pastes were found to be
unadulterated. Shrimp paste, which was at one time heavily adulterated
with boric acid, is evidently now being made from fresh
shrimps.
Tinned Vegetables.—The use of copper sulphate as a colouring agent
has been reduced by the action of the Council to small amounts—under
2 grains per lb. Proceedings had to be taken against one retailer for
selling peas with 3.45 grains per lb., and against another for selling
spinach with 10.21 grains per lb. This latter was seated to be the last
tin of some old stock.
Olive Oil.- The custom of selling some other cheaper oil as olive oil
appears to have ceased for the present in Westminster, as only one such
was discovered in 29 samples.
