HOG CHOLEBA AND MEAT INSPECTION 205 



F. ; these are condemned or isolated for further 

 temperature records; in case further tempera- 

 tures are taken the animals are condemned if the 

 readings are still above 106; otherwise they fall 

 into class three or class five : fifth, apparently nor- 

 mal hogs that show temperatures below 106; 

 these pass ante-mortem inspection and post-mor- 

 tem as well if they do not show lesions of hog chol- 

 era in organs other than the kidneys or lymph 

 glands. 



Let us consider the individual hog. Briefly 

 stated, the requirements in order that it may pass 

 inspection are that it shall not show conclusive 

 symptoms of hog cholera, it shall not show sus- 

 picious symptoms plus hog cholera lesions, it shall 

 not maintain repeated temperature readings above 

 106 F., and regardless of ante-mortem findings 

 the carcass shall not on post-mortem show hog 

 cholera lesions in organs other than the kidneys or 

 lymph glands. What are the chances for car- 

 casses that contain hog cholera virus to pass in- 

 spection ? 



This question is best answered by considering 

 the average case of hog cholera. Let us suppose 

 that a hog becomes infected to-day. According to 

 Dorset, "Bepeated experiments have shown that 

 the blood of pigs that have previously been in- 

 oculated with the virus of cholera becomes infec- 

 tious for others within twenty-four hours; the
