Parasites: A Treatise on the Entozoa of Man and Animals: Including Some Account of the Ectozoa

“After explaining to them the possible consequences of eating it a
buttock of beef studded with _Cysticercus_ was given to three natives of
low caste. They all declared that they were free from _Tænia_, or, to
use their own term, “Kadhu dana.” The meat they cooked in their own way.
These men were under my observation for some six months. Two of them had
no symptom of _Tænia_, but the third, who was a low-class Mahommedan
syce, and had probably eaten the meat in a very raw state, developed a
_Tænia mediocanellata_ in about three months.
“My own sweeper ate this cyst-infected beef regularly two or three times
a week for some months. He cooked it well generally as an ordinary stew,
and has never shown a sign of having tapeworm.
“Into the food of a boy of low Hindoo caste, but who had never eaten
beef, two scolices of Cysticercus were surreptitiously introduced, the
result being that, between three or four months afterwards, he applied
for some tapeworm medicine.”
[The two successful experiments here reported are evidently the same
as those that I have referred to (p. 72) as having been performed by
Dr Oliver, of the Royal Artillery, stationed at Jullundur. The report
continues as follows:]
“_Tænia mediocanellata_ is very common amongst the Mussulman population
of the Punjab, and from reliable sources I am informed that the lower
classes amongst them are in the regular habit of eating half-cooked
beef; indeed, prefer it so, and it is amongst these people that tapeworm
is so prevalent.
“But it is not only thorough cooking that is required to guard soldiers
in India from the ill effects of eating measly meat; there is want of
cleanliness in the general arrangements of the kitchens and serving of
meals, which must offer great facilities for the introduction into the
food of Cysticercus.
“Barrack cooks, unless constantly looked after, are utterly careless
as to the washing of chopping blocks, tables, dishes, &c. The dish or
pot cover on which the meat is placed when raw is often used without
washing for serving the piece up for dinner, and I have myself picked
up a _Cysticercus_ from the table on which a cook was preparing food.
The dangers too of the parasite being conveyed by the cook’s unwashed
hands to the plates in which meals are served, and the common practice
of using the same knife for cutting up meat, and afterwards, without
washing it, for other culinary purposes, must not be overlooked. With
good selection and careful feeding there seems to be every probability
that Cysticercus would soon almost or completely disappear from our
Commissariat cattle. If they were entirely stall-fed and watered from
wells there could scarcely be a possibility of infection after their
purchase.
“Perhaps with the trench system of conservancy, which will necessitate
the growing up crops, a sufficient quantity of root and other green
produce may be obtained from cantonment lands set apart for this
purpose, to supply green fodder for the cattle.”
