carbolic acid or with a solution containing 2 per cent, of cresol. When cresol 

 is used it must be mixed with soft soap in order to render it easily soluble in 

 cold water.] 



Swine Plague and Hog Cholera 



§ 24. 1. Manure, bedding, feed residue, etc., removed from infected 

 pens are to be composted (§ 14, subdivision 1, No. 1). If this is not feasible, 

 then these materials are to be burned or buried with the cadavers of animals 

 which die or are destroyed. The rejected parts of slaughtered diseased ani- 

 mals are also to be buried or burned and the offal, including the water used 

 to wash the meat and viscera, is to be rendered harmless. 



2. The passageway between the pens, the place before the stable door, the 

 entrance to the yard and the roads to the stable and on the farm are to be 

 cleaned and disinfected with dilute calcium chloride solution or 6 per cent, 

 cresol water at least every 8 days during the continuance of the disease. 



3. Utensils, vehicles, vessels and other articles which have come in con- 

 tact with diseased or suspected animals or with their eliminations are to be 

 disinfected before being removed from the premises. 



4. At the final disinfection the places in which the diseased or suspected 

 animals have been kept (pens and adjoining compartments such as the feed- 

 cooking room, exercise place, yard, breeding pen, stock-yards, railroad stock 

 pens, etc.), the utensils (buckets, forks, shovels, troughs, etc.) used in caring 

 for and in slaughtering such animals, the vehicles and sleds used to haul the 

 cadavers, straw, manure and other offal, the clothing and foot-gear of the 

 attendants, feed sacks and other articles which have come in contact with 

 diseased or suspected animals or which there is reason to assume may be 

 infected, are to be cleaned and disinfected. Special attention is to be given 

 to objects contaminated with the manure, urine and blood of diseased or 

 suspected animals. The manure and straw are to be removed from the rooting- 

 place and the superficial layer of earth is to be removed, after which, if pos- 

 sible, the surface of the ground is to be thoroughly saturated with dilute 

 calcium chloride solution or with 6 per cent, cresol water, then raked or har- 

 rowed until level and repeatedly saturated with the disinfectants named. 

 New swine brought on to the premises are to be kept away from the rooting- 

 place as long as possible. Earth removed from the floors and other places is 

 to be removed to fields not accessible to swine and buried or plowed under. 



5. The disinfection of the pens and other compartments used by diseased 

 or suspected animals is to be carried out according to the directions in § 14. 

 As disinfectants, dilute calcium chloride solution or 6 per cent, cresol water 

 are to be used.
