198 ESSENTIALS OF VETERINARY LAW 
provide for systematic supervision of the meat 
production by the Department of Agriculture; 
provides for post mortem examination by inspect- 
ors of the Department, and the exclusion from in- 
terstate or foreign commerce of such meats or 
meat products as show evidences of disease, pre- 
servatives, coloring matter or disease producing 
substances. 
The Act of October 3, 1913,37 provides for the 
importation of certain articles free of duty, but 
subjects imported meats to examination. 
The Food and Drugs Act of June 30, 1906,*§ 
provides for the exclusion of articles from inter- 
state or foreign commerce on account of mislabel- 
ing, or for adulteration. The administration of 
this act is in charge of the Bureau of Chemistry 
of the Department of Agriculture. 
153. Intrastate Meat Industries. Only a little 
over one half of the animals slaughtered in the 
United States are slaughtered under federal super- 
vision. In 1907 it was estimated that approxi- 
mately 5,000,000 cattle, 8,000,000 sheep, and over 
10,000,000 hogs and 3,000,000 calves were slaugh- 
tered by butchers in this country without federal 
supervision, and most of them without any efficient 
supervision at all. Added to these should be 
1,500,000 cattle, 1,000,000 sheep, and 16,500,000 
hogs slaughtered by farmers. Approximately two 
per cent of carcasses examined by federal officers 
are condemned, and it may easily be seen that the 
percentage of animals slaughtered for intrastate 
consumption which should be condemned would 
be much greater. The federal government is with- 
8738 Stat. 114, 152, 159, 9834 Stat. 768.
