true course is to cook if before it leaves the place of slaughter. 

 By superheating and canning the danger of infection is absolutely 

 done away with. 



.">. An obvious precaution is to allow no tableware, napkins, etc., 

 which have been used by an affected person, to be made use of by 

 one in health, until the same has been cleansed and thoroughly 

 scalded. 



6. Equal care should be taken to secure the disinfection, by heat 

 or otherwise, of all products of the infected person, of his clothing 

 and of whatever has conic in contact with him. In country districts 

 where there is danger not only to human beings, but to live stock, 

 the removal of tic patient to a hospital where all possible pre- 

 cautions may lie used is a commendable resort. 



It should be added that infection from man is very infrequent; 

 yet as the possibility of this has been abundantly proven by experi- 

 ment, precautions against it cannot be looked on as superfluous. 

 In such an inveterat* ly contagious disease, success depends on 

 closing every avenue of escape for the contagion, and the certainty 

 of success is the one excuse tor the interference with commerce 

 and industries which an effective veterinary sanitary police 

 demand-. 



PREVENTION [X ANIMALS 

 EXCLUSION FROM AX UNINFECTED COUNTRY 



For a country like tic United States which habitually is and 

 always should lie free from this disease, prevention consists pri- 

 marily in the exclusion of all live stock bearing^infection, and of 

 all products of such animals and every object that may be a bearer 

 of such products. 



As far as the live animals are concerned, the most thorough 

 measure is to forbid the importation of any ruminant or swine 

 coming from a country where aphthous fever exists. This should 

 be as inclusive as the genera named, covering all such animals for 

 menagerie, or acclimatization, or otherwise, as well as those for 

 ordinary domestic uses. 



As a corollary of the above, comes the refusal of admission of 

 any such live stock arriving on a ship, which may have clearance 

 papers from an unaffected country, but which, on a very recent 

 voyage, has carried cattle, slice]), goats or swine from an infected
