Trichinew in Pigs 355 
severe soreness of the muscles, associated with fever. 
During this stage, the young trichine are migrating, 
working their way through the tissues of the body. In 
general, it has been said that the symptoms of trichi- 
nosis in man are those of “rheumatism, associated with 
typhoid fever.” The disease has never been recognized 
by any symptoms shown by pigs. Pigs do not die of 
trichinosis. The worms can be found in the muscular 
tissue by making a microscopical examination. In ex- 
amining the carcasses of pigs for trichine, specimens 
of lean meat should be taken from the deeper muscles 
of the neck, inner face of the shoulder, “midriff” or 
diaphragm, tenderloin, or the base of the tongue, as 
the parasites are most frequent in these regions. Esti- 
mates as to the prevalence of trichinosis in pigs varies 
from two to ten per cent. Pigs that are kept in un- 
sanitary or filthy quarters and fed upon offal are more 
frequently diseased. There is no remedy. Pork or ham 
should never be eaten without a most thorough cooking.
