AND PARTS--Table of Contents

 

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

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.
