DISINFECTANTS. ANTISEPTICS 199 



Regtilation 45. Cars and other vehicles and pens or yards which have 

 contained interstate shipments of diseased or exposed swine shall be cleaned 

 and disinfected as soon as possible after unloading. Cars that have contained 

 interstate shipments of swine shall not be removed until the inspector has 

 ascertained the condition of the live animals and either released the cars or 

 given notice that they shall be cleaned and disinfected. Cleaning and dis- 

 infection shall be done by first removing all litter and manure and then satu- 

 rating the interior surfaces of the cars and the woodwork, flooring, and ground 

 of the chutes, alleys, and pens with a 5 per cent, solution of pure carboUc 

 acid in water, 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 water. (Subsequently, it was found that a 3 per cent, solution of the official 

 liquor cresolis compositus was more efficient than the carbolic acid solution.)] 



Swine Erysipelas 



§ 25. 1. When swine erysipelas is present, the cleaning and disinfection 

 includes, as a rule, the pen occupied by the diseased or suspected animal; 

 when several cases occur a certain portion of the building or the entire build- 

 ing occupied by swine is to be disinfected, as in the judgment of the official 

 veterinarian may be necessary; also, the equipment, utensils and other ob- 

 jects which have come in contact with diseased or suspected animals or their 

 excretions, cadavers or cadaver parts. The pen occupied by the diseased or 

 suspected animals, a portion of the building or the entire building, as may 

 be required, is to be cleaned and disinfected immediately after the death, 

 slaughter or removal of all the swine, or within 6 days after the last case of 

 the disease. 



2. The disinfection is to be made as directed in § 13. Any of the disin- 

 fectants named in § 11, subdivision 1, may be employed. 



Fowl Cholera and Fowl Pest 



§ 26. 1. The coops and other compartments occupied by diseased or 

 suspected fowl, the cages, other containers and transportation crates, the run, 

 baths or swimming pools, the utensils and other objects which have come in 

 contact with such fowl, their excretions, cadavers or cadaver parts, and the 

 places where such fowl have been slaughtered are to be cleaned and disinfected 

 as prescribed in § 14. Any of the disinfectants named in § 11, subdivision 1, 

 may be employed. 



2. Special attention must be given to the eliminations of diseased or sus- 

 pected fowl and to blood escaping at the slaughter of the same. This offal 

 is to be carefully collected and buried or burned with the cadavers, together 

 with the litter, manure, feathers, feed residue, earth removed from unpaved 

 floors and from the run, and all other objects of slight value which are con- 

 taminated with manure or blood. Rejected parts of slaughtered, diseased or
