from the GNU version of the Collaborative International Dictionary of English
- n. A small, slender nematoid worm (Trichina spiralis) which, in the larval state, is parasitic, often in immense numbers, in the voluntary muscles of man, the hog, and many other animals. When insufficiently cooked meat containing the larvæ is swallowed by man, they are liberated and rapidly become adult, pair, and the ovoviviparous females produce in a short time large numbers of young which find their way into the muscles, either directly, or indirectly by means of the blood. Their presence in the muscles and the intestines in large numbers produces trichinosis.
from The Century Dictionary and Cyclopedia
- n. An important genus of nematoid worms, typical of the Trichinidæ.
- n. [lowercase; pl. trichinæ (-nē), sometimes trichinas (-näz).] A worm of this genus.

It sometimes contains a parasite called trichina, which may be transferred to the human system, producing disease and often death.
Intestinal trichina that produces young; 2. a young trichina pushes into a muscle; 3. young trichinae; 4. muscle with trichinae in cysts; 5. living; 6. dead trichinae in cysts enlarged.
There was an excitement, just then, about the trichina germ in pork, and one of his memoranda says:
Upon awakening, should not the "ridiculous man," having been admitted to an earthly paradise only to act in it as the agent of corruption — "a horrible trichina, a germ of the plague" — finally carry out his initial resolve to kill himself?
These developed in the alimentary tract of the cockroaches into larvae, which, like the trichina, were distributed into the muscles of the insects where they become encapsulated.
In the case of the larger parasites, such as the tapeworms and the trichina, there is a direct interchange of disease with animals, certain phases of the life cycle of the organisms are passed in man and others in various of the domestic animals.
There is the trichina spiralis, which really exists, although the German pork-butchers denounce the story as a "pig lie;" the ordinary intestinal worm, which disports itself, eel-like, in the Alimentary Canal; and the tape worm, of two varieties, one of which performs its circumlocutory antics in the human stomach, and the other in the government Bureaux at
Not only do bacteria become innocuous through cooking, but various parasites, as trichina and tapeworm, are destroyed, although some organisms can live at a comparatively high temperature.
He invariably approached a subject with a refreshing originality, and on one occasion maintained with an obstinacy born of conviction that the reason Moses had prohibited the Jews from eating pork was because he had discovered the trichina.
The tapeworms, common in many animals and often occurring in man, the roundworms of which the trichina (Fig. 3) that causes "measly" pork is a representative, are familiar examples.
