558 APPENDIX II 
testines, weasands, and bladders from beef carcasses affected with Cysticercus bovis 
which have been passed for food or for sterilization may be used for casings after they 
have been subjected to the usual methods of preparation and may be passed for such 
purpose upon completion of the final inspection. 
Paragraph 5. The inspection for Cysticercus bovis may be omitted in the case of 
calves under six weeks old. The routine inspection of calves over six weeks old for 
Cysticercus bovis may be limited to a careful examination of the surface of the heart 
and such surfaces of the body musculature as are rendered visible by the process of 
dressing 
Section 17. Carcasses of hogs affected with tapeworm cysts (Cysticercus cellulose) 
may be passed for sterilization, but if the infestation is excessive the carcass shall be 
condemned. 
Smction 18. Paragraph 1. In the disposal of carcasses, edible organs, and parts 
of carcasses showing evidence of infestation with parasites not transmissible to man, 
the following general rules shall govern: If the lesions are localized in such a manner 
and are of such a character that the parasites and the lesions caused by them may be 
radically removed, the nonaffected portion of the carcass, organ, or part of the car- 
cass may be passed for food after the removal and condemnation of the affected por- 
tions. If an organ or a part of a carcass shows numerous lesions caused by parasites, 
or if the character of the infestation is such that complete extirpation of the parasites 
and lesions is difficult and uncertainly accomplished, or if the parasitic infestation 
or invasion renders the organ or part in any way unfit for food, the affected organ 
or part shall be condemned. If parasites are found to be distributed in a carcass 
in such a manner or to be of such a character that their removal and the removal of 
the lesions caused by them are impracticable, no part of the carcass shall be passed 
for food. If the infestation is excessive the carcass shall be condemned. If the infesta- 
tion is moderate the carcass may be passed for sterilization, but in case such carcass 
is not sterilized as required by regulation 15 it shall be condemned. 
Paragraph 2. In the case of sheep carcasses, affected with tape-worm cysts located 
in the muscles (Cysticercus ovis, so-called sheep measles, not transmissible to man) 
the carcass may be passed after the removal and condemnation of the affected portions; 
provided, however, that if upon the final inspection of sheep carcasses retained on 
account of measles the total number of cysts found embedded in muscle or in immediate 
relation with muscular tissue, including the heart, exceeds five, this shall be taken to 
indicate that the cysts are so generally distributed and so numerous that their removal 
would be impracticable, and the entire carcass shall be condemned or passed for 
sterilization, according to the degree of infestation. If not to exceed five cysts are 
found upon final inspection, the carcass may be passed after the removal and con- 
demnation of the affected portions. 
Paragraph 3. Carcasses of animals found infested with gid bladder worms (Cenurus 
cerebralis, Multiceps multiceps) may be passed after condemnation of the affected 
organ (brain or spinal cord). 
Paragraph 4. Organs or parts of carcasses infested with hydatid cysts (Echinococ- 
cus) shall be condemned 
Paragraph 5. Livers infested with flukes shall be condemned. 
Section 19. Carcasses of animals too emaciated or anemic to produce wholesome 
meat. and carcasses which show a slimy degeneration of the fat or a serous infiltration 
of the muscles, shall be condemned. 
Section 20. Carcasses of animals in advanced stages of pregnancy (showing signs 
of parturition), also carcasses of animals which have within ten days given birth to 
young and in which there is no evidence of septic infection, may be passed for steriliza- 
tion: otherwise, they shall be condemned. 
Section 21. Paragraph 1. Carcasses of calves, pigs, kids, and lambs too immature 
to produce wholesome meat shall be condemned. Such carcasses shall be considered 
too immature to produce wholesome meat if (a) the meat has the appearance of being 
water-soaked, is loose, flabby, tears easily, and can be perforated with the fingers; 
or () its color is grayish red; or (c) good muscular development as a whole is lacking, 
especially noticeable on the upper shank of the leg, where small amounts of serous 
infiltrates or small edematous patches are sometimes present between the muscles; or
