666 VETERINARY HYGIENE 



and liver must be made for any indication of septic inflam- 

 mation or pya3mic disease. In pigs evidence of cysticerci 

 should be sought in the muscle of the cheeks, diaphragm, 

 tongue, heart, pectoral, intercostal, and neck muscles, while 

 the vertebral column and sternum should be examined for 

 tubercular disease. The examination for trichina is micro- 

 scopical, the specimens selected being taken from the pillars 

 of the diaphragm, abdominal, intercostal, and laryngeal 

 muscles. The disease is so rare in this country that no 

 routine examination is made. In Germany an army of 

 inspectors is retained for the purpose, principally women, 

 and payment is largely though not entirely by results. 

 McFadyean tells us that in the Berlin abattoir alone the 

 annual cost of inspection amounts to £25,000. 



An examination of dressed carcases sent for inspection 

 without the viscera is nearly valueless, even if accompanied 

 by the viscera there is no evidence they belong to the 

 carcase under inspection. If an opinion on a dressed 

 carcase is demanded, an examination of the peritoneal and 

 pleural sacs, bone marrow, and all available lymphatic 

 glands, should be made. A stripped pleura should at once 

 condemn the whole, when the carcase has been sent in 

 dressed without the organs, or in the case of foreign meat. 

 In connection with this subject there are many carcases 

 which, with the permission of the Inspector, it might be 

 allowable to strip for marketable purposes — for example, an 

 echinococcus cyst on the periphery of the lung, or a local 

 pleurisy, or a local and circumscribed abscess from injury. 

 In looking for evidence of septicaemia in the examination 

 of a dressed carcase, a microscopical examination of the 

 bone marrow is often of great value. The microbes of 

 anthrax, swine erysipelas, and other septicemic diseases, 

 remain for a considerable time in a state of purity in the 

 bones of the limbs. 



The bones can be sterilized by boiling, and kept in an 

 antiseptic solution for future reference, or for submission 

 to an expert. 



The muscles of such a carcase should be carefully exam-
