Sec. 189.155  Monochloroacetic acid.

    (a) Monochloroacetic acid is the chemical chloroacetic acid, 
C2H3C1O2. It is a synthetic chemical 
not found in natural products, and has been proposed as a preservative 
in alcoholic and nonalcoholic beverages. Monochloroacetic acid is 
permitted in food package adhesives with an accepted migration level up 
to 10 parts per billion (ppb) under Sec. 175.105 of this chapter. The 
official methods do not detect monochloroacetic acid at the 10 ppb 
level.
    (b) Food containing any added or detectable level of 
monochloroacetic acid is deemed to be adulterated in violation of the 
act based upon trade correspondence dated December 29, 1941 (TC-377).
    (c) The analytical methods used for detecting monochloroacetic acid 
in food are in sections 20.067-20.072 of the ``Official Methods of 
Analysis of the Association of Official Analytical Chemists,'' 13th Ed. 
(1980), which is incorporated by reference. Copies may be obtained from 
the Association of Official Analytical Chemists International, 481 North
