are only slightly infested may properly be passed for food after the 
removal of the parasites, but carcasses showing a heavy infestation should 
be condemned. Moderately infested carcasses may be rendered into 
edible tallow, but are usually treated the same as condemned carcasses 
and are manufactured into fertilizer and other inedible products. As 
C. ovis is not transmissible to man, meat-inspection regulations concern¬ 
ing it need not be so stringent in certain respects as those governing 
beef measles or pork measles. 
The length of time Cysticercus ovis may survive after the death of its 
host has not been determined. 
The most important preventive measures against the infestation of 
sheep with Cysticercus ovis consist, first, in destroying by fire the car¬ 
casses of dead sheep on the farm or range so that they may not be 
devoured by dogs or wolves, and, second, in keeping dogs free from 
tapeworms by systematic medicinal treatment. These measures will 
also protect sheep from infestation with tapeworm cysts of various 
other kinds, which they acquire from dogs.
