Upon opening the suspicious tins, in many instances, it
was found that the contents were, owing to advanced decomposition,
obviously unfit for human food.
In the case of four tins of boiled rabbit and one tin of oxtongue,
the jelly was liquified. Apart from this fact there was
no evidence of the contents being unfit for human food.
Three tins of salmon suspected, showed no distinct signs
of unfitness upon being opened. These, with other suspicious
tins of various foods which had been surrendered, were
submitted for bacteriological examination, with the following
results
One tin boiled rabbit (A- brand):—
The tin of boiled rabbit marked A— brand has been
found to contain living motile bacilli, which by their
action have completely liquified the jelly in which the
meat was embedded.
One tin of boiled rabbit (B— brand):—
The contents of this tin were found to be free from
living organisms.
One tin boiled rabbit (C— brand):—
The contents are free from organisms.
One tin boiled rabbit (A— brand):—
The contents of this tin are seen to be free from living
organisms.
One tin of ox tongue (D— brand):—
After a few hours' incubation at 37 degrees C. the tin
became distended with gas. Numerous microorganisms
were seen in a hanging drop preparation
made from the contents.
