Sec. 319.5  Mechanically Separated (Species).

    (a) Mechanically Separated (Species) is any finely comminuted 
product resulting from the mechanical separation and removal of most of 
the bone from attached skeletal muscle of livestock carcasses and parts 
of carcasses and meeting the other provisions of this paragraph. 
Examples of such product are ``Mechanically Separated Beef'', 
``Mechanically Separated Veal'', ``Mechanically Separated Pork'', and 
``Mechanically Separated Lamb''. At least 98 percent of the bone 
particles present in such product shall have a maximum size no greater 
than 0.5 millimeter in their greatest dimension and there shall be no 
bone particles larger than 0.85 millimeter in their greatest dimension. 
The product resulting from the separating process shall not have a 
calcium content exceeding 0.75 percent, as a measure of a bone solids 
content of not more than 3 percent, and shall have a minimum PER of 2.5 
(except as modified in paragraph (e)(1) of this section). Such product 
also shall have a protein content of not less than 14 percent and a fat 
content of not more than 30 percent, or it shall be deemed to be product 
for processing. Such product failing to meet the bone particle size, 
calcium, or PER requirements of this paragraph shall only be used in 
producing animal fats. Where such product meets the bone particle size, 
calcium, and PER requirements of this paragraph, it may also be used in 
the formulation of meat food products in accordance with Sec. 319.6.
    (b) Mechanically Separated (Beef) is inedible and prohibited for use 
as human food.
    (c)-(d) [Reserved]
    (e)(1) An essential amino acid content of at least 33 percent of the 
total amino acids presents in ``Mechanically Separated (Species)'' shall 
be accepted as evidence of compliance with the protein quality 
requirement set forth in paragraph (a) of this section. For purposes of 
this paragraph, essential amino acid content includes isoleucine, 
leucine, lysine, methionine, phenylalanine, threonine, and valine 
content, and the total amino acids present include isoleucine, leucine, 
lysine, methionine, phenylalanine, threonine, valine, tyrosine, 
arginine, histidine, alanine, aspartic acid, glutamic acid, glycine, 
proline, serine, and hydroxyproline content.
    (2) Analytical methods used by establishments in verifying the fat, 
protein, and calcium content of product consisting of or containing 
Mechanically Separated (Species) shall be among those listed in 
``Official Methods of Analysis of the Association of Official Analytical 
Chemists (AOAC),'' 16th edition, 1995, Sec. Sec. 960.39, 976.21, 928.08 
(Chapter 39), and 940.33 (Chapter 45), which is incorporated by 
reference, or, if no AOAC method is available, in the ``Chemistry 
Laboratory Guidebook,'' U.S. Department of Agriculture, Washington, 
D.C., March 1986 edition, sections 6.011-6.013, Revised June 1987 (pages 
6-35 through 6-65), or by appropriate methods validated by scientific

the Association of Official Analytical Chemists,'' Chapter 39 and 
Chapter 45, subsection 45.2.06 (AOAC Official Method 940.33), 16th 
edition, 1995, are incorporated by reference with the approval of the 
Director of the Federal Register in accordance with 5 U.S.C. 552(a) and
