The importance of meat inspection is becoming more evi¬ 
dent every day. A layman or butcher is not qualified to do 
work of this character. It requires the services of the veteri¬ 
nary expert. The danger is not so much from meat of inferior 
quality, or even from putrid meat, as it is from fresh meat con¬ 
taining micro-organisms of communicable diseases. Certain 
parasites ( Cysticercus cellulosa and C. bovis) are directly trans¬ 
missible to man through the use of meat. The veterinarian 
with a knowledge of these worms is able to prevent the spread 
of their tapeworm stage among human beings by condemning 
the infested meat or subjecting it to processes which will render 
it harmless. The rigid system of meat inspection in Germany 
has resulted in an actual decrease in tapeworm disease (by 
Tcenia solium and probably also by T. sciginata ) in man and 
in their frequency of C. celluloses in the human eye. 
Condemnation and destruction of organs infested with cer 
tain other parasites (. Echinococcus , Coenurus , Cysticercus tenui- 
collis ) will prevent the spread of those parasites in their tape 
worm stage to dogs, and by that means prevent the reinfection 
of man {by echinococcus ), and of domesticated animals [by echi¬ 
nococcus ', Coenurus , Cysticercus tenuicollisy, in this case preven¬ 
tion of tapeworm disease in dogs, though of comparatively lit¬ 
tle importance so far as the dogs are concerned, becomes very 
important not only in public hygiene (in the prevention of dis¬ 
ease in man and animals), but also from an economic stand¬ 
point, preventing financial loss to stock-raisers from disease and 
death in their herds and flocks caused by the worms. The de¬ 
struction of livers heavily infected with flukes will also result 
indirectly in decreasing fluke diseases in man and animals. I 
would refer those interested to an exhaustive work on the sub¬ 
ject compiled by the Bureau of Animal Industry, some of the 
data of which I have incorporated in this paper. 
Pork before being put on the market should be examined 
microscopically for a minute worm called trichina spiralis ,
