(k) Blue Culinary Colouring.
This sample contained two permitted colouring matters, but the container did not
bear the statutory statement required by the Colouring Matters in Food Regulations.
The packers were informed and labels incorporating the statutory statement were
brought into use.
(1) Preserved Por\ Sausages.
This sample was found to contain 60 per cent of meat whereas the accepted
amount should be 65 per cent. The manufacturer, a retail butcher, was interviewed
and advised to ensure that future supplies should contain at least 65 per cent meat
content.
(m) Preserved Por\ Sausages.
Although there are no statutory standards for the meat content of pork sausages
there is an accepted standard of 65 per cent. This informal sample was found to
contain only 51 per cent. A formal sample was taken and reported upon as being
genuine.
(n) Sausage Meat.
This sample was found to contain a colouring matter and the intensity of colour
produced was considered to be excessive. The colouring matter was one which is permitted
under the Colouring Matters in Food Regulations, 1966, and as there is no
statutory limit to the quantity permitted, the manufacturers were advised and no
further action taken.
(o) Salad Cream.
Partial separation of the oil had occurred and this was attributed to its being old
stock. Similar aged stocks at the shop were withdrawn from sale.
(p) Salad Dressing.
The emulsion in the mayonnaise had partially broken down and also one of the
ingredients in the article was partially deleted from the label. It was found that the
sample was from old stock and that present stocks were appropriately labelled.
(q) Curry Powder.
This sample contained a quantity of acid insoluble ash in excess of that normally
present in similar powders. Stocks of the product were withdrawn from sale.
(4) Milk Supplies and Sampling.
Licences granted authorising dealers to store and sell designated milks were as
follows :
Ultra Heat Treated 34
Pasteurised 95
Sterilised 62
Untreated 29
There are no processing plants in the Borough but there is one Dairy Farm which
is registered by the Ministry of Agriculture, Fisheries and Food.
Fifty four samples of milk were submitted for examination of which fifty three
satisfied the prescribed tests. The sample reported as being unsatisfactory was a carton
of milk taken from a vending machine. The sample failed to satisfy the methylene
blue test — a test applied to assess the bacterial and keeping quality of milk. The
dairy company were informed of the occurrence and were advised to exercise the
strictest control over the renewal of supplies in the machine. Further samples were
taken and found to be satisfactory. Fifteen samples of milk were also examined for
the presence of brucella abortus, brucella melitensis and mycobactenum tuberculosis.
These were reported upon as being negative.
