Organs contain- ing hydatids should be destroyed by burning in order to prevent their being eaten by dogs. This is especially important, as dogs infested with the tape- worm stage of this parasite are a menace to human beings on account of the danger of infecting them with hydatids, which develop in man if the eggs of the hydatid tapeworm are swallowed. Thin-necked bladder worms (Toznia hydatigena, fig. 25) are most commonly found attached to the mesentery and omentum.

Small tapeworm cysts {Toznia saginata), about the size of a pea, found in the muscles of cattle (fig. 26) are the larvsa of the common tapeworm of man. Cattle become infected from feed or water which has been contaminated by the feces of persons harboring the adult tapeworms, and human beings in turn become infected by eating raw or rare beef infested with the larval stage (measly beef)..
