TRICHINE IN SALTED MEAT.
Sailing No sure Protection Against
the Parasite.

Sailing NO sure Protection Against
the Parasite.
Ever since the discovery of trichine
in pork, the question has been often
asked as to how the small worms could
be completely destroyed. A French
savant, M. Colin, some time ago de-
clared that the sailing of meat was a
sure and certain method of destruction
to these parasites. This, however, was
different to the opinions often express
ed by German investigators, and also
to the fact that several cases of trichi-
niosis, believed to have resulted from
the eating of American hams that had
long been sailed, had been reported.
Among other chemists, Schmitt, Cha
tim, Girard, and Pabst, ard DeBenecke
end Libon, may be mentioned as OBJ
servers who had found the trichine still
living in meats that had been sailed for
several months. The experiments of
M. Colin led to others by M. Fourment,
the results of which have just been
published as a report to the French
academy.
These experiments show conclusively
that the sailing of meats cannot be re-
garded as safeguard against trichino-
is. Mr.. Feurment took a piece of
meat on the 10Th of April, 1881, from
some American sailed meats examined
at the Havre docks, and found it in
tested. This meat was placed in a
flask and imbedded in fine salt. 1t was

opened till the LIST of April, 1882
Ru No 49,
gone years sailing carried to the
highest degree, and if we add the
time that must have elapsed since it
was first put in salt in America (which
could not be put at less than three
months), the meat may be said to have
been in salt for at least fifteen months.
The meat was then cut up in small
pieces, and these were placed in water,
which was frequently changed to re-
move the salt, and remained for several
hours in temperature of II degrees
Fahrenheit. On the 4th, 9Th, and 9th of
April this was fed to mouse, which
died on the 9TH, after presenting symp-
toms of diarrhea. The intestine was
evidently infamed, and contained
sexually developed trichin@. A second
and third mouse were fed with more
of the meat, and with exactly similar
results in each case. Several other ex-
periments were made. M. Four
ment says that all show that
the trichina were then certainly
alive and capable of reproduc.
ton, after fifteen months OF
sailing; and it is consequently manifest
that sailing does not surely and rapidly
destroy these parasites. They may die
in sailed meats as well as in any other
situation, and thus explain the negative
experiments published by distinguishe ed
observers; but they ay also live q
considerable timewith out our being
able to determine the length of the
follows latent life. 1T is also proper to
point out that, while sailing is too often
powerless to kill the trichin@, one effect
is to remove them to q certain extent
from the action of heat. This fact is
plainly shown by the experiments Of
Doyere Lrborda.
II may be useful to point out here
that, although several psychologists
have found that sailing does not destroy
ments they We're found to be killed
Zundel, Louis, Rechlinhausen, Kopp
Seigmand, and Dele all made numer.
Gus experiments, and in none was il
| found that, after treating with salt. the
trichin@ were capable of development
and reproduction. 1t is very probable
that the solution of these disagreement
is to be found in the life history of the
trichina, 1t may be pointed out tina
when the trichin@ penetrates the mus
Giles they are perfectly free, and have
no covering whatever to protect them
and month or more elapses before
they accept the situation and coil them
selves up, to quietly await their chance
of being eaten up by some other AMI
NAL, which must occur before they car
possibly develop into the perfect adult
condition. But It is only at the end Of
three months that fibrcus cyst begins
to form around them, and it is, per
haps, year before the covering is suf-
ficiently dense and impermeable to en-
tirely protect it from the action of salt
Thus it is seen that at one stage in the
life of the trichin@ salt may effectually
destroy them, while at another stage II
would be almost powerless to act.
But, although sailing is thus an IN.
certain remedy, there need be no dan.
ger whatever from trichonosis if only
the meat be properly cooked. In nc
single case-and there have been nu.
merous experiments made-has heat
failed to destroy these parasites. Fjord
in Sweden, and Krabbe, in Germany
have both proved thai temperature
of 129 degrees Fahrenhit kills trichina
if maintained for fifteen minutes, while
1853 degrees Fahrenheit has been shown
by many experiments to kill instanta-
neously. Only those who neglected the
precaution of thorough cooking abso
lutely necessary in the case of all pie
meat and ges-need be under any
fear CT these pqrasites.-LOYsdoa Times.
