Tapeworm.

The film begins with a health officer holding a tape worm with a pair of tweezers. Then a series of images aims to illustrate how the body can become infested with a tape worm. We see a boy go into a bush to defecate on land where cattle and pigs are grazing. A butcher is shown cutting meat; he holds up a piece of meat with tape worms in. Infected meat is thrown into a pit and covered. We see people at a health clinic where a young boy with stomach pains is given medicine - this time he goes to the toilet in a hut type WC.
