This book contains the rules and regulations constituting Parts 1 to 119 of
Title 21, Revised as of January 1, 1967. It is one of two volumes that re-
places the volume entitled "Title 21-Food and Drugs, Parts 1 to 129, Re-
vised as of January 1, 1966," and becomes an integral part of the Code of
Federal Regulations.
The text in this revision is derived from the latest text of the rules and
regulations, general and permanent in nature, duly promulgated in the
Federal Register on or before December 31, 1966. Source materials from
which the text is derived are cited with the text and should be consulted
to determine the effective date of any given provision. All dates appear-
ing in the source citations are dates of publication in the Federal Register
and should not be construed as effective dates.
Current regulatory material appearing in the daily issues of the Federal
Register follows the numbering system used herein and serves as a daily
supplement hereto. This book contains the following finding aids: a list
of current CFR volumes; a list of superseded CFR volumes; a table of
CFR titles and chapters; an alphabetical list of CFR subtitles and chap-
ters; and a list of sections affected which furnishes Federal Register cita-
tions to all changes in this book beginning January 1, 1964, including
changes which are no longer in effect.
A compilation of the list of sections affected for the entire Code of Federal
Regulations from January 1, 1949, through December 31, 1963, is pub-
lished in a separate volume entitled "List of Sections Affected, 1949-1963."
A General Explanation of the Code of Federal Regulations appears in
the volume containing Titles 1-3, and in the General Index volume.
This volume is published pursuant to Part 30 of the regulations of the
Administrative Committee of the Federal Register, as revised December 7,
1965 (30 F.R. 15131; 1 CFR Part 30), under the authority contained in
section 11 of the Federal Register Act, as amended (67 Stat. 388 as
amended; 44 U.S.C. 311). The contents of the Federal Register and the
Code of Federal Regulations are by law prima facie evidence of the text
of the original documents and are required to be judicially noticed (49
Stat. 502, 67 Stat. 388; 44 U.S.C. 307, 311). The approved citation of
the Code is "CFR". Thus the citation "21 CFR 1.1" refers to section 1.1
