 equipment, utensils, blankets, cleaning implements and other objects which 

 have come in contact with such animals are to be cleaned and disinfected. 

 When the animals are treated by dipping, the cleamng and disinfection is to 

 be carried out at each dipping. If the animals are treated by hand applica-

 affected with mange before slaughter, or before treatment was begun, must 

 be immediately cleaned and disinfected after the diseased animals are 

 removed. 



3. The disinfection is carried out as directed in § 14. As disinfectants, 

 dilute cresol water, carbolic acid solution or lime are to be used. Special 

 attention is to be given to all objects with which the diseased or suspected 

 animals have come in contact (mangers, racks, posts, pillars, stalls, tie ropes,
