ized in accordance with regulation 15 and until so sterilized shall remain in the custody 
of a bureau employee. 
Paragraph 2. In all cases where carcasses showing localized lesions of disease are 
passed for food or for sterilization the diseased parts shall be removed before the 
“U.S. retained” tag is taken from the carcass, and such parts shall be condemned. 
Section 6. Carcasses and parts found to be sound, healthful, wholesome, and fit 
for human food shall be passed and marked as provided in these regulations. 
Section 7. Hog carcasses found before evisceration to be affected with an infec- 
tious or contagious disease, including tuberculosis, shall not be eviscerated at the 
regular killing bed or bench, but shall be retained and separated from other carcasses 
and taken to the final inspection room or place and there opened and examined. This 
requirement, however, may be waived for those slaughter floors where the number 
of animals slaughtered per hour is small and on which the inspection facilities are such 
-as permit a ready, efficient, and sanitary performance of the final inspection without 
-such separation. 
SEcTION 8. Paragraph 1. When a carcass is to be dressed with the skin or hide 
left on, the skin or hide shall be thoroughly washed and cleaned before evisceration. 
Paragraph 2. All hair, scurf, and dirt shall be removed from hog carcasses and 
the carcasses thoroughly washed and cleaned, before any incision is made for inspection 
-or evisceration. 
Paragraph 3. Skins and hides from animals condemned for tuberculosis or any 
disease communicable to man or other animal may be removed from the establishment, 
-except as provided in section 2 of regulation 11, for tanning or other industrial use; 
but they shall be removed for these uses only after disinfection as follows: Each skin 
-or hide shall be immersed for not less than five minutes in a 5 per cent solution of 
‘liquor cresolis compositus, or a 5 per cent solution of carbolic acid. The process of 
skinning and dipping shall be conducted entirely in the retaining room, or other 
‘specially prepared place approved by the inspector in charge, and under the supervi- 
sion of a bureau employee. 
Section 9. The sternum of each carcass shall be split and spread apart at the time 
of slaughter so as to expose the lungs, heart, liver, and thoracic cavity, in order to 
allow proper inspection and drainage. 
Section 10. Carcasses or parts of carcasses shall not be inflated with air. Trans- 
ferring the caul or other fat from fat to lean carcasses is prohibited. 
Section 11. When only a portion of a carcass is to be condemned on account of 
slight bruises, either the bruised portion shall be removed immediately and tanked 
or the carcass shall be immediately placed in a retaining room and kept until chilled 
and the bruised portion then removed and tanked. 
Regulation 11. Disposal of Diseased Carcasses and Parts. 
Section 1. The carcasses or parts of carcasses of all animals slaughtered at an 
-official establishment and found at the time of slaughter or at any subsequent inspec- 
tion to be affected with any of the diseases or conditions named in other sections of 
this regulation shall be disposed of according to the section of this regulation pertaining 
‘to the disease or condition. Owing to the fact that it is impracticable to formulate 
rules covering every case and to designate at just what stage a process becomes loath- 
some ora disease noxious, the decision as to the disposal of all carcasses, parts, or organs 
not specifically covered by these regulations shall be left to the inspector in charge. 
Section 2. All parts, including hides, hoofs, horns, viscera, intestinal contents, 
fat, and blood, of animals the carcasses of which show lesions of anthrax, regardless 
-of the extent of the disease, shall be condemned and immediately incinerated or other- 
wise completely destroyed. The killing bed upon which the animal was slaughtered 
shall be disinfected with a 1 to 1,000 solution of bichlorid of mercury, and all knives, 
saws, cleavers, and other instruments which have come in contact with the carcass 
shall be treated as provided in paragraph 3 of section 7 of regulation 8 before being used 
‘upon another carcass. : ; 
Section 3. Paragraph 1. The following principles are declared for guidance in 
-passing on carcasses affected with tuberculosis:
