Sec. 311.23  Tapeworm cysts (cysticercus bovis) in cattle.

    (a) Except as provided in paragraph (b) of this section, carcasses 
of cattle affected with lesions of cysticercus bovis shall be disposed 
of as follows:
    (1) Carcasses of cattle displaying lesions of cysticercus bovis 
shall be condemned if the infestation is extensive or if the musculature 
is edematous or discolored. Carcasses shall be considered extensively 
infested if in addition to finding lesions in at least two of the usual 
inspection sites, namely the heart, diaphragm and its pillars, muscles 
of mastication, esophagus, tongue, and musculature exposed during normal 
dressing operations, they are found in at least two of the sites exposed 
by (i) an incision made into each round exposing the musculature in 
cross section, and (ii) a transverse incision into each forelimb 
commencing 2 or 3 inches above the point of the olecranon and extending 
to the humerus.
    (2) Carcasses of cattle showing one or more tapeworm lesions of 
cysticercus bovis but not so extensive as indicated in paragraph (a)(1) 
of this section, as determined by a careful examination, including 
examination of, but not limited to, the heart, diaphragm and its 
pillars, muscles of mastication, esophagus, tongue, and musculature 
exposed during normal dressing operations, may be passed for human food 
after removal and condemnation of the lesions with surrounding tissues: 
Provided, That the carcasses, appropriately identified by retained tags, 
are held in cold storage under positive control of a USDA Food Inspector 
at a temperature not higher than 15 [deg]F. continuously for a period of 
not less than 10 days, or in

[[Page 139]]

the case of boned meat derived from such carcasses, the meat, when in 
boxes, tierces, or other containers, appropriately identified by 
retained tags, is held under positive control of a Program Inspector at 
a temperature of not higher than 15 [deg]F. continuously for a period of 
not less than 20 days. As an alternative to retention in cold storage as 
provided in this subparagraph, such carcasses and meat may be heated 
throughout to a temperature of at least 140 [deg]F. under positive 
control of a Program Inspector.
    (b) Edible viscera and offal shall be disposed of in the same manner 
as the rest of the carcass from which they were derived unless any 
lesion of cysticercus bovis is found in these byproducts, in which case 
they shall be condemned.
