16 BULLETIN 880, U. S. DEPARTMENT OF AGRICULTURE. 
The data presented in Tables 7 and 8 show that the sausage in the 
6 experiments that yielded positive results was held for periods 
ranging from 13 to 20 days, and that the sausage in the 13 experi- 
ments that yielded negative results was held for 13 to 19 days. The 
difference in results is accordingly not to be explained on the basis 
of differences in the drying period. Evidently the method of smoking 
sausages for a few hours and then drying for 10 days is not a reliable 
method for the destruction of trichine. 
The detailed results of the feeding tests with the sausage that 
produced infections are as follows: 
Experiment 101.—¥our rats were fed in Washington, of which 1 
developed a heavy infection, 2 developed slight infections, and 1 
escaped infection entirely. The results of feeding experimental 
animals in Chicago were also positive. The sausage was 2 days in 
transit from Chicago to Washington. 
Experiment 104.—An examination of several decapsuled larve in 
the laboratory at Washington showed that most of them were uncoiled, 
but that a few were coiled and active. Four rats fed portions of the 
sausage developed heavy infections. The results of feeding animals 
in Chicago were also positive. This sausage was 3 days in transit 
from Chicago to Washington. 
Experiment 105.—Three rats were fed in the laboratory at Wash- 
ington; 2 escaped infection and 1 developed aslght infection, showing 
but 2 encysted trichine in the diaphragm. Results positive in Chi- 
cago. Thesausage was 2 days in transit from Chicago to Washington. 
Experiment 107.—Results of feeding experiments in Washington 
negative; positive in Chicago. The sausage was 2 days in transit 
from Chicago to Washington. 
Exnervment 108.—-Six rats were fed in Washington; 3 developed 
moderate infections and 3 escaped infection. Results in Chicago posi- 
tive. The sausage was 2 days in transit from Chicago to Washington. 
Experiment 114.-—-Three rats fed in Washington developed mild 
infections. Results in Chicago positive. The sausage was 4 days in 
_ transit from Chicago to Washington. 
The data with reference to this sausage indicate that trichine may 
show considerable variation in vigor and resistance to unfavorable 
conditions, since larve from certain carcasses survived treatment 
apparently similar to that under which larvee from other carcasses 
failed to survive. 
SAUSAGE SMOKED AT TEMPERATURES OF ABOUT 125° TO 130° F. 
A considerable number of experiments were carried out at four 
establishments to determine the possibility of preparing sausage of 
kinds customarily eaten without cooking so as to obviate the necessity 
of a relatively long period of drying and yet render the product 
innocuous so far as concerns trichinee. To compensate for the omission 
of drying, high-temperature smoking was substituted. This further
