This is a film about trichinosis, mostly how it spreads.

The really odd thing is, it's a silent COLOR film. Why?

Most disgusting: the human. He handles everything, from infected meat to infected rat intestines, with his bare hands!

Trichinosis is no longer as prevalent as it used to be in the industrialized world, but if you've ever wanted to learn more about the disease and how it manifests itself in the animals that it infects, this silent colour film will provide you with a comprehensive overview. Compelling microscope footage and informative intertitles are used to explain how the trichina larvae develop in various organisms and how they can be detected in uncooked pieces of meat. Longstanding members of the squeamish set certainly won't be too fond of an early scene in the film in which a hog chews away at the carrion of an infected rat, and they will undoubtedly reel in disgust when they observe a scientist infecting an anaesthetized laboratory rat with the parasite so that he can later examine the animal's intestine for the elucidation of the viewer. A very helpful introduction to the subject, even if it is somewhat dated.
