The inspection as now carried out is of great importance, not only to 
the public because of giving them a more wholesome meat supply, but 
also to the live stock industry in general by materially checking the 
spread of certain contagious diseases and protecting and keeping open 
foreign markets for our surplus meat products. 
Again, the records of the post mortem inspection furnish valuable 
knowledge of the prevalence of the more common diseases of meat ani- 
mals and by comparing the records from year to year, it may be ascer- 
tained whether these diseases are on the decrease or increase. 
Thus it is demonstrated that tuberculosis of cattle and swine is on the 
increase, while hog cholera and its allied diseases have been gradually 
diminishing for several years. 
The stock raisers could receive valuable lessons if more of them would 
call upon the inspectors and go with them and look over the diseased 
carcasses. By such a method, they would not only learn what diseases 
are prevalent, but they would become familiar with the appearances — 
pathology — of the various diseases; and by questioning and discussion of 
the various questions with the inspectors, they could gain valuable infor- 
mation relative to the freeing and keeping their animals free from dis- 
ease. 
RECOMMENUATIOX. 
The Iowa State Board of Health recommends that all dairy and breed- 
ing cattle used in the State of Iowa be tested with tuberculin at intervals 
of one year, until it is determined that such herds are free from tuber- 
culosis. The board also recommends that every dairyman and breeder 
when purchasing cattle, be required to see that such animals are free 
from tuberculosis, as determined by the tuberculin test. It is recom- 
mended that the council of every city, town or village in the State of 
Iowa, adopt a milk and dairy ordinance similar to, or incorporate the 
provisions embodied in the copy for as ordinance as given below.
