PART 311_DISPOSAL OF DISEASED OR OTHERWISE ADULTERATED CARCASSES

AND PARTS--Table of Contents

 

Sec. 311.25  Parasites not transmissible to man; tapeworm cysts in sheep; hydatid cysts; flukes; gid bladder-worms.



    (a) In the disposal of carcasses, edible organs, and other parts of 

carcasses showing evidence of infestation with parasites not 

transmissible to man, the following general rules shall govern except as 

otherwise provided in this section: If the lesions are localized in such 

manner and are of such character that the parasites and the lesions 

caused by them can be completely removed, the nonaffected portion of the 

carcass, organ, or other part of the carcass may be passed for human 

food after the removal and condemnation of the affected portions. If an 

organ or other part of a carcass shows numerous lesions caused by 

parasites, or if the character of the infestation is such that complete 

extirpation of the parasitic infestation or invasion renders the part in 

any way unfit for human food, the affected part shall be condemned. If 

parasites are found to be distributed in a carcass in such a manner or 

to be of such character that their removal and the removal of the 

lesions caused by them is impracticable, no part of the carcass shall be 

passed for human food. If the infestation is excessive, the carcass 

shall be condemned. If the infestation is moderate, the carcass may be 

passed for cooking, but in case such carcass is not cooked as required 

by part 315 of this subchapter, it shall be condemned.

    (b) In the case of sheep carcasses affected with tapeworm cysts 

(Cysticercus ovis, so-called sheep measles, not transmissible to man), 

such carcasses may be passed for human food 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 muscular tissue, or in 

immediate relation with muscular tissue, excluding the heart, exceeds 

five, the entire carcass shall be condemned, or such carcass shall be 

heated throughout to a temperature of at least 140 [deg]F. After removal 

and condemnation of all affected portions.

    (c) Carcasses found infested with gid bladder-worms (Coenurus 

cerebralis, Multiceps multiceps) may be passed for human food after 

condemnation of the affected organ (brain or spinal cord).

    (d) Organs or other parts of carcasses infested with hydatid cysts 

(echinococus) shall be condemned.

    (e) Livers infested with flukes or fringed tapeworms shall be 

condemned.
