Withdrawal of Notices of Opportunity
for a Hearing; Penicillin and
Tetracycline Used in Animal Feed
AGENCY:
Food and Drug Administration,
HHS.
ACTION:
Notice.
The Food and Drug
Administration (FDA or the Agency) is
withdrawing two 1977 notices of
opportunity for a hearing (NOOH),
which proposed to withdraw certain
approved uses of penicillin and
tetracyclines intended for use in feeds
for food-producing animals based in
part on microbial food safety concerns.1
(Refs. 1 and 2) FDA is taking this action,
and closing the corresponding dockets,
because: FDA is engaging in other
ongoing regulatory strategies developed
since the publication of the 1977
NOOHs with respect to addressing
microbial food safety issues; FDA would
update the NOOHs to reflect current
data, information, and policies if, in the
future, it decides to move forward with
withdrawal of the approved uses of the
new animal drugs described in the
NOOHs; and FDA would need to
prioritize any withdrawal proceedings
(for example, take into account which
withdrawal(s) would likely have the

SUMMARY:
1 FDA’s approval to withdraw the approved uses
of the drugs was based on three statutory grounds:
(1) The drugs are not shown to be safe (21 U.S.C.
360b(e)(1)(B)); (2) lack of substantial evidence of
effectiveness (21 U.S.C. 360b(e)(1)(C)); and (3)
failure to submit required reports (21 U.S.C.
360b(e)(2)(A)).

any new animal drug or class of drugs.
FDA is also withdrawing the companion

SUPPLEMENTARY INFORMATION:
I. Background
Questions regarding the use of
antimicrobial drugs in food-producing
animals have been raised and debated
for many years. (Ref. 5) 2 Following a
report that was issued by the British
government in 1969 on the use of
antibiotics in veterinary medicine and
animal husbandry, known as the
‘‘Swann Report,’’ the Commissioner of
Food and Drugs established a task force
to review the use of antibiotic drugs in
animal feeds. The task force, established
in 1970, included specialists on
infectious diseases and animal science
from FDA, the National Institutes of
Health, the U.S. Department of
2 The term ‘‘antimicrobial’’ refers broadly to drugs
with activity against a variety of microorganisms
including: Bacteria, viruses, fungi, and parasites.
Antimicrobial drugs that have specific activity
against bacteria are referred to as antibacterial or
antibiotic drugs. However, the broader term
‘‘antimicrobial,’’ commonly used in reference to
drugs with activity against bacteria, is used in this
document interchangeably with the terms
antibacterial or antibiotic. Antimicrobial resistance
is the ability of bacteria or other microbes to resist
the effects of a drug. Antimicrobial resistance, as it
relates to bacterial organisms, occurs when bacteria
change in some way that reduces or eliminates the
effectiveness of drugs, chemicals, or other agents
designed to treat bacterial infections. (Ref. 5)

Agriculture, and the Centers for Disease
Control and Prevention, as well as
representatives from universities and
industry. The task force identified three
primary areas of concern (human health
hazard, animal health hazard, and
antibiotic effectiveness) and guidelines
were established to show whether the
use of any antibiotic or antibacterial
agent in animal feed presents a hazard
to human and animal health. (Refs. 1
and 6) The task force also made certain
recommendations concerning
restrictions on the use of antibiotic
drugs in animal feeds at growth
promotion and subtherapeutic levels.
(Ref. 6)
In 1972, FDA published the
conclusions and recommendations of
that task force and proposed to require
sponsors to submit specific data for
antibiotic drugs in animal feeds
intended for subtherapeutic or growth
promotion use when such drugs are also
used in human clinical medicine. (Ref.
6) In 1973, FDA finalized this proposal
in 21 CFR 135.109 (re-codified at 21
CFR 558.15 in 1974).3 (Refs. 7, 8, and 9)
This section provided that FDA would
propose to revoke approved uses in
animal feed of antibiotic and
sulfonamide drugs unless certain data
were submitted which satisfactorily
addressed the outstanding safety and
effectiveness issues.
By 1974, FDA had begun to review
the data submitted by the sponsors of
the antibiotic products and requested
that the National Advisory Food and
Drug Committee (NAFDC) review the
data and make recommendations on the
subtherapeutic uses of penicillin and
tetracyclines. A subcommittee (the
Antibiotics in Animal Feeds
subcommittee) was appointed to work
in conjunction with expert consultants
to address these issues. With respect to
the penicillin-containing drugs, the
subcommittee recommended FDA
immediately withdraw approval of the
subtherapeutic uses of penicillin. The
3 Since that time, portions of 21 CFR 558.15 have
been removed because those portions of the
regulation were determined to be redundant or
obsolete. (See 75 FR 16001, March 31, 2010.)

NAFDC accepted the subcommittee’s
recommendation and recommended to
FDA that it ‘‘immediately withdraw
approval for the subtherapeutic uses of
penicillin, i.e., growth promotion/feed
efficiency, and disease control.’’ 4 (Ref.
1) FDA accepted these
recommendations. (Ref. 1)
With respect to the tetracyclinecontaining drugs, the subcommittee
recommended that FDA: (1) Discontinue
use for growth promotion and/or feed
efficiency in all animal species for
which effective substitutes are available;
(2) permit their use for disease control
where effective alternate drugs are
unavailable; and (3) control the
distribution of the tetracyclines to
restrict their use. NAFDC did not accept
the subcommittee’s first two
recommendations, and instead
recommended that FDA make no
changes in the permitted use of
chlortetracycline and oxytetracycline in
animal feed. (Ref. 2) The NAFDC did
adopt the subcommittee’s third
recommendation that the addition of the
tetracycline in feeds be restricted. (Ref.
2) FDA considered these
recommendations and decided to
propose withdrawal of approval of
subtherapeutic uses of tetracyclines in
animal feeds except for those conditions
of use for which there are no safe and
effective substitutes. (Ref. 2)
This process culminated in the 1977
publication of two NOOHs in the
Federal Register on proposals by the
Bureau of Veterinary Medicine (now
Center for Veterinary Medicine) to
withdraw all uses of penicillin in
animal feed, and all subtherapeutic uses
of tetracycline in animal feed except for:
(1) Oxytetracyline, as an aid in the
control of fowl cholera caused by
Pasteurella multocida in chickens and
infectious synovitis caused by
Mycoplama synoviae in chickens and
turkeys; and (2) chlortetracycline (a) as
an aid in the maintenance of weight
gains in the presence of respiratory
diseases, such as shipping fever, in
combination with sulfamethazine in
beef cattle, (b) as an aid in the control
of infectious synovitis caused by M.
pasteurella in chickens and turkeys, (c)
for the control of active infections of
anaplasmosis in beef cattle, and (d) as
an aid in reducing the incidence of
virbrionic abortion in breeding sheep.

published on August 30, 1977
(penicillin) and October 21, 1977
(tetracycline).
At the same time, FDA also published
two companion proposed rules
proposing to amend the regulations to
delete those provisions referencing the
approved penicillin and tetracycline
uses that would be affected by a
withdrawal. (Refs. 3 and 4) FDA did not
withdraw any approved use of
penicillin or tetracyclines intended for
use in feeds for food-producing animals
as a result of these NOOHs, or finalize
the proposed companion rules, and
some new animal drug approvals for the
use of these new animal drugs in feeds
for food-producing animals remain in
effect.
Although FDA initially granted some
hearing requests to provide sponsors
with the opportunity to present
evidence on the safety of the NOOH
products, Congress intervened before
any hearing was held, directing FDA to
hold in abeyance the implementation of
its proposed withdrawal actions
pending the outcome of further research
related to the use of antibiotics in
animal feed. (Refs. 10, 11, and 12)
II. Discussion
At this time, FDA is withdrawing the
1977 NOOHs because: (1) FDA is
engaging in other ongoing regulatory
strategies developed since the
publication of the 1977 NOOHs with
respect to addressing microbial food
safety issues; (2) FDA would update the
NOOHs to reflect current data,
information, and policies if, in the
future, it decides to move forward with
withdrawal of the approved uses of the
new animal drugs described in the
NOOHs; and (3) FDA would need to
prioritize any withdrawal proceedings
(for example, take into account which
withdrawal(s) would likely have the
most significant impact on the public
health) if, in the future, it decides to
seek withdrawal of the approved uses of
any new animal drug or class of drugs.
Although FDA is withdrawing the
1977 NOOHs, FDA remains concerned
about the issue of antimicrobial
resistance. Today’s action should not be
interpreted as a sign that FDA no longer
has safety concerns or that FDA will not
consider re-proposing withdrawal
proceedings in the future, if necessary.
FDA has not ruled out the prospect of
future regulatory action, either with
respect to the antimicrobial new animal
drugs covered by the 1977 NOOHs or
any others. However, as discussed
further in this document, FDA intends
0019, and Docket Number 77N–0316 is now Docket
Number FDA–1977–N–0022.

to focus its efforts for now on the
potential for voluntary reform and the
promotion of the judicious use of
antimicrobials in the interest of public
health. Importantly, this strategy leaves
open the possibility of pursuing
withdrawal proceedings at a later time
if FDA’s proposed strategy does not
yield satisfactory results.
1. FDA Is Engaging in Other Ongoing
Regulatory Strategies Developed Since
the Publication of the 1977 NOOHs
With Respect to Addressing Microbial
Food Safety Issues
Since the 1977 NOOHs published,
FDA has continued to investigate the
safety concerns associated with
subtherapeutic uses of antibiotics
intended for use in feeds for foodproducing animals. As mentioned
previously, Congress directed FDA to
hold proceedings with respect to the
1977 NOOHs in abeyance and instead to
conduct more research on the issues in
question. (Ref. 10, 11, and 12) In
response, FDA contracted with the
National Academy of Sciences (NAS) to
conduct a study of the safety issues
related to the use of antibiotics in
animal feed. (Refs. 5 and 13) In
particular, FDA asked the NAS to: (1)
Study the human health effects of the
subtherapeutic use of penicillin and
tetracycline in animal feed; (2) review
and analyze published and unpublished
epidemiological and other data
necessary to assess human health
consequences of such use; (3) assess the
scientific feasibility of additional
epidemiological studies; and (4) make
recommendations about additional
research needed. (Refs. 5 and 9)
The NAS issued its report in 1980,
concluding that a very limited amount
of epidemiological research had been
completed on either the subtherapeutic
or therapeutic use of antimicrobials in
animal feeds and that existing data
could neither prove nor disprove the
postulated hazards to human health
from subtherapeutic antimicrobial use
in animal feed. (Refs. 5 and 9) The
report stated that ‘‘[t]he lack of data
linking human illness with
subtherapeutic levels of antimicrobials
must not be equated with proof that the
proposed hazards do not exist. The
research necessary to establish and
measure a definitive risk has not been
conducted and, indeed, may not be
possible.’’ (Refs. 5 and 13)
In 1984, FDA contracted with the
Seattle-King County Health Department
to complete a study intended to provide
additional information regarding
potential public health concerns
regarding the use of antimicrobial drugs
in animal feed. The study focused on

the relationship between the occurrence
of Salmonella spp. (Salmonella) and
Campylobacter jejuni (C. jejuni) in foods
of animal origin and the occurrence of
human illness caused by those two
organisms. The study report indicated
that the bacteria obtained from human
cases and those obtained from retail
poultry had similar antibiotic
susceptibility patterns, including
similar levels of resistance to
tetracycline. (Refs. 5 and 14)
In 1987, FDA asked the Institute of
Medicine to conduct an independent
review of the human health risks
associated with the subtherapeutic uses
of penicillin and tetracycline in animal
feed. (Refs. 5 and 15) The IOM
established a committee which
developed a risk-analysis model using
data on Salmonella infections that
resulted in human death. (Refs. 5 and
15) The Committee did not find a
substantial body of direct evidence
establishing conclusively the presence
of a human health hazard resulting from
the use of subtherapeutic concentrations
of penicillin and the tetracyclines in
animal feeds. (Refs. 5 and 15)
Nonetheless, the Committee found a
considerable body of indirect evidence
implicating both the subtherapeutic and
therapeutic use of antimicrobials as a
potential human health hazard, and
made recommendations for further
study of the issue.6 (Refs. 5 and 15)
During the 1990’s, FDA continued to
investigate the potential risks associated
with the use of antibiotic drugs
intended for use in feeds for foodproducing animals and how to mitigate
risks associated with such use. In 1999,
FDA published a concept paper titled,
‘‘Proposed Framework For Evaluating
and Assuring the Human Safety of the
6 FDA’s draft guidance titled ‘‘The Judicious Use
of Medically Important Antimicrobial Drugs in
Food-Producing Animals’’ (Draft GFI #209) contains
information on additional key studies relevant to
this issue. For example, in 1997, the World Health
Organization (WHO) issued a report which
concluded that all uses of antimicrobials lead to the
selection of resistant forms of bacteria and that
‘‘low-level, long-term exposure to antimicrobials
may have greater selective potential than shortterm, full-dose therapeutic use.’’ (Ref. 17) The WHO
report contained several recommendations,
including a recommendation that the use of
antimicrobial drugs for growth promotion in
animals be terminated if these drugs are also
prescribed for use as anti-infective agents in human
medicine or if they are known to induce crossresistance to antimicrobials used for human
medical therapy. (Ref. 17) It also recommended that
national practices of antimicrobial use in animals
be reviewed, and policies be developed to reduce
the risks of selection and dissemination of
antimicrobial resistance. (Ref. 17) Further, in 1999
the National Research Council issued a report that,
among other things, recommended that further
development and use of antibiotics in both human
and animal medicine have oversight by an
interdisciplinary panel of experts. (Ref. 18)

19:17 Dec 21, 2011
Jkt 226001
Microbial Effects of Antimicrobial New
Animal Drugs Intended for Use in FoodProducing Animals’’ (‘‘Framework
Document’’). (Ref. 19) Among other
things, the Framework Document called
for revisions to the pre-approval safety
assessment for antimicrobial new
animal drugs, and the categorization of
antimicrobial drugs based on their
importance to human medicine. (Ref.
19)
In 2003, FDA published a final
guidance for industry (GFI #152),
outlining an approach for conducting a
qualitative risk assessment to evaluate
human food safety with respect to the
potential microbiological effects of
antimicrobial new animal drugs on
food-borne bacteria of human health
concern. (Ref. 20) The importance of a
drug for human medical therapy is a key
factor to be considered in the
evaluation. (Ref. 20) Since 2003, FDA
has applied the principles contained in
GFI #152 when assessing antimicrobial
resistance risks for antimicrobial drugs
as part of the new animal drug approval
process. In some cases, this has had the
effect of limiting the claims for which
such drugs are approved while still
protecting animal and human health.
Recognizing that already-approved
antimicrobial new animal drugs also
have antimicrobial resistance risks
associated with their use, FDA began to
look at the safety of some of these
already approved drugs. However,
because the process of reviewing safety
information for antimicrobial drugs
approved before 2003 (and pursuing
withdrawal proceedings if appropriate
in some cases) would take many years
and would impose significant resource
demands on the Agency, FDA began
thinking about alternate approaches to
address safety concerns. As a result, in
June 2010 FDA proposed a different
strategy to promote the judicious use of
medically important antimicrobials in
food-producing animals in a draft
guidance for industry titled ‘‘The
Judicious Use of Medically Important
Antimicrobial Drugs in Food-Producing
Animals’’ (draft GFI #209). (Ref. 5)
Generally speaking, judicious uses
would be those uses that are appropriate
and necessary to maintaining the health
of humans and animals.
Draft GFI #209 proposes two
principles aimed at ensuring the
judicious use of medically important
antimicrobials in food-producing
animals. The first principle described in
the draft guidance is that the use of
medically important antimicrobial drugs
in food-producing animals should be
limited to those uses that are considered
necessary for assuring animal health.
(Ref. 5) As set out in the draft guidance,
PO 00000
Frm 00054
Fmt 4703
Sfmt 4703
79699
FDA does not consider production uses
of such drugs to be necessary for
assuring animal health because, unlike
other uses, production uses are not
directed at any specifically identified
disease, but rather are expressly
indicated and used for the purpose of
enhancing the production of animalderived products (e.g., promoting faster
weight gain or improving feed
efficiency). (Ref. 5) The second
principle set out in the draft guidance
is that the use of medically important
antimicrobial drugs in food-producing
animals should be limited to those uses
that include veterinary oversight or
consultation. (Ref. 5) This principle
speaks to the need for the scientific and
clinical training of licensed
veterinarians to assure that medically
important antimicrobials are used in a
judicious manner.
Based on feedback the Agency
received following the issuance of draft
GFI #209, FDA believes that the animal
pharmaceutical industry is generally
responsive to the prospect of working
cooperatively with the Agency to
accomplish the principles
recommended in draft GFI #209. FDA
intends to work with sponsors who
approach FDA and are interested in
working cooperatively with the Agency
to phase out production uses of
medically important antimicrobials, and
to achieve an orderly transition of
medically important antimicrobials
currently approved for over-the-counter
use in food-producing animals to a
marketing status that involves
veterinary oversight (i.e., veterinary feed
directive (VFD) status for feed use drugs
and prescription status for drugs
approved for use through other routes of
administration).
As part of the proposed strategy, FDA
issued an advance notice of proposed
rulemaking (ANPRM) on March 29,
2010 (75 FR 15387), to seek public
comment on whether and to what extent
efficiency improvements should be
made to the current VFD process as set
forth in FDA’s regulation at 21 CFR
558.6. (Ref. 21) FDA received numerous
public comments in response to the
ANPRM and is taking those comments
into account in considering possible
revisions to this regulation.
FDA believes that the strategy set out
in draft GFI #209 represents another
pathway to achieving the same goals
contemplated by the 1977 NOOHs, i.e.,
the judicious use of medically important
antimicrobial drugs. FDA believes that
by implementing this strategy and
proceeding in part under the statutory
authority provided under the Animal
E:\FR\FM\22DEN1.SGM

to designate drugs as VFD drugs
(authority which was not available in
1977), it will achieve its goal of
promoting the judicious use of
antimicrobial drugs in a more timely
and resource-efficient manner than
could be accomplished otherwise.8

2. FDA Would Update the NOOHs To
Reflect Current Data, Information and
Policies If, in the Future, it Decides To
Move Forward With the Withdrawal of
the Approved Uses of the New Animal
Drugs Described in the NOOHs
Although FDA is optimistic that its
proposed strategy to achieve the
judicious use of all medically important
antimicrobials, as set out in draft GFI
#209, will be successful, it has not
foreclosed the possibility of using the
withdrawal provisions in the Federal
Food, Drug, and Cosmetic Act, if
necessary, in the future. This applies
not only to the classes of antimicrobial
drugs covered by the 1977 NOOHs, but
also any other production use claims
(i.e., growth promotion/feed efficiency
uses) for a medically important
antimicrobial new animal drug or class
of drugs intended for use in foodproducing animals. However, if FDA
were to pursue withdrawal of approval
of any production use claims, it would
first publish a notice in the Federal
Register giving the sponsor(s) of the
affected new animal drug(s) notice of
the proposed withdrawal(s) and an
opportunity for a hearing.
If, at some future time, FDA decides
to proceed with the withdrawal of the
production uses of penicillins and
tetracyclines intended for use in feeds
for food-producing animals that were
the subject of the 1977 NOOHs, it would
publish a new Federal Register notice
giving sponsors an opportunity for a
hearing on the matter. A new notice
would be appropriate for many reasons.
7 ADAA (Pub. L. 104–250), which was signed into
law on October 9, 1996, introduced several
amendments to the Federal Food, Drug, and
Cosmetic Act that provided FDA with more
flexibility in how it regulates animal drugs and
animal feeds. One such amendment made by the
law was to add a new ‘‘veterinary feed directive’’
category of new animal drugs to allow the approval
and use of drugs in animal feed on a veterinarian’s
order while incorporating safeguards to help ensure
the safe use of the drug.
8 FDA’s experience with contested, formal
withdrawal proceedings is that the process can
consume extensive periods of time and significant
amounts of Agency resources. For example, when
FDA withdrew a class of animal drugs called
nitrofurans in 1991, the proceedings took nearly 20
years. In another proceeding, the withdrawal of
diethylstilbestrol (‘‘DES’’) in animals became final
in 1979, 7 years after issuance of an NOOH. More
recently, the withdrawal of enrofloxacin for use in
poultry took almost 5 years and cost FDA
approximately $3.3 million.

First, more than three decades have
passed since the original notice
appeared in the Federal Register. FDA
would publish a new Federal Register
notice to ensure all current sponsors of
the approved new animal drugs are
properly notified and have an
opportunity to request a hearing.
Second, not all uses proposed to be
withdrawn in the 1977 NOOHs are still
approved. The 1977 NOOH which
proposed withdrawal of all penicillincontaining premixes intended for use in
animal feed also included the thenapproved therapeutic uses of penicillin
in feed. The stated grounds for
proposing to withdraw approval of the
therapeutic uses of the penicillincontaining premixes were that there was
not substantial evidence of effectiveness
of these products for the claimed
therapeutic uses. However, there are no
currently approved therapeutic uses of
penicillins in animal feed.
Third, the body of scientific
information relevant to the use of
penicillins and tetracyclines in animal
feeds has grown since 1977. If the
Agency were to pursue the NOOHs,
FDA would need to provide notice to
the sponsors that the information
available since 1977 would be used to
support the proposal to withdraw the
approved uses of the drugs.
For example, in the early 1990’s FDA
began collaborating with other
government agencies to track antibiotic
resistance in foodborne bacteria through
a national public health surveillance
system, known as the National
Antimicrobial Resistance Monitoring
System or ‘‘NARMS,’’ established to
monitor antimicrobial susceptibility
among enteric bacteria from humans,
retail meats, and food animals. (Ref. 22)
Also, since the 1977 NOOHs published,
there have been numerous reports,
including those by the National
Academy of Sciences (Ref. 13), the
Institute of Medicine (Ref. 15), the
World Health Organization (Ref. 17),
and the National Research Council (Ref.
18), that have reviewed available
information and made
recommendations. In addition, there
have been advances in our
understanding of the genetics of
resistance (e.g., ways in which bacteria
accumulate multiple resistance genes).
Fourth, FDA would need to provide
notice regarding which approved uses
were the subject of the NOOH. In the
past, FDA has referred to
‘‘subtherapeutic’’ uses at various times
to include: (1) ‘‘Increased rate of gain,
disease prevention, etc.’’ (Ref. 7); (2)
‘‘any use of an antibacterial drug
continuously in feed for longer than 14
days’’ (Ref. 23); and (3) ‘‘lower levels
PO 00000
Frm 00055
Fmt 4703

than therapeutic levels needed to cure
disease.’’ (Refs. 1 and 2) FDA’s thinking
on this issue has evolved over the last
three decades, and FDA now generally
considers disease control and
prevention claims to be judicious uses
(in other words, therapeutic uses),
especially when the drug is
administered at the direction and under
the oversight of a licensed veterinarian.

3. FDA Would Need To Prioritize Any
Withdrawal Proceedings (for Example,
Take Into Account Which Withdrawal(s)
Would Likely Have the Most Significant
Impact on the Public Health) if, in the
Future, It Decides To Seek Withdrawal
of the Approved Uses of Any New
Animal Drug or Class of Drugs
To the extent that FDA decides to
move forward with withdrawal
proceedings for any medically
important antimicrobial drugs intended
for use in feeds for food-producing
animals, it would need to prioritize
which withdrawal(s) to propose first
based on various considerations,
including which withdrawal(s) would
have the most significant impact on the
public health. It is possible that FDA
would conclude that its judicious use
goals would better be achieved by first
pursuing withdrawals of drugs other
than penicillins and tetracyclines. FDA
notes that it would need to conduct
such an evaluation regardless of the
statutory grounds contemplated for the
withdrawal action.
III. Conclusion
At this time, FDA is withdrawing the
1977 NOOHs because: (1) FDA is
engaging in other ongoing regulatory
strategies developed since the
publication of the 1977 NOOHs with
respect to addressing microbial food
safety issues; (2) FDA would update the
NOOHs to reflect current data,
information, and policies if, in the
future, it decides to move forward with
withdrawal of the approved uses of the
new animal drugs described in the
NOOHs; and (3) FDA would need to
prioritize any withdrawal proceedings
(for example, take into account which
withdrawal(s) would likely have the
most significant impact on the public
health) if, in the future, it decides to
seek withdrawal of the approved uses of
any new animal drug or class of drugs.
Although FDA is withdrawing the
1977 NOOHs, FDA continues to view
antimicrobial resistance as a significant
public health issue. Today’s action
should not be interpreted as a sign that
FDA no longer has safety concerns
about the use of medically important
antibiotics in food producing animals or
E:\FR\FM\22DEN1.SGM
22DEN1
Federal Register / Vol. 76, No. 246 / Thursday, December 22, 2011 / Notices
that FDA will not consider re-proposing
withdrawal proceedings in the future, if
necessary. FDA has not ruled out the
prospect of future regulatory action,
either with respect to the antimicrobial
new animal drugs covered by the 1977
NOOHs or any others. However, for
now, FDA’s efforts will focus on
promoting voluntary reform and the
judicious use of antimicrobials in the
interest of best using the agency’s
overall resources to protect the public
health. Importantly, this strategy leaves
open the possibility of pursuing
withdrawal proceedings at a later time
if FDA’s proposed strategy does not
yield satisfactory results.
As indicated previously, as part of the
withdrawal of the two 1977 NOOHs, the
Agency will close their corresponding
dockets. However, we encourage
interested persons to submit comments
to the docket established in connection
with draft GFI #209. The docket number
associated with draft GFI #209 is FDA–
2010–D–0094.

IV. Penicillin and Tetracycline Uses in
Animal Feed
FDA is withdrawing the 1977 NOOHs,
and the related companion proposed
rules, because: (1) FDA is engaging in
other ongoing regulatory strategies
developed since the publication of the
1977 NOOHs with respect to addressing
microbial food safety issues; (2) FDA
would update the NOOHs to reflect
current data, information, and policies
if, in the future, it decides to move

would need to prioritize any withdrawal
proceedings (for example, take into

likely have the most significant impact
on the public health) if, in the future, it
decides to seek withdrawal of the
approved uses of any new animal drug
or class of drugs.

Bristol-Myers Squibb Co. et al.;
Withdrawal of Approval of 70 New
Drug Applications and 97 Abbreviated
New Drug Applications; Correction
AGENCY:
Food and Drug Administration,
HHS.
ACTION:
Notice; correction.
The Food and Drug
Administration (FDA) is correcting a
notice that appeared in the Federal
Register of June 8, 2011 (76 FR 33310).
The document announced the
withdrawal of approval of 70 new drug
applications (NDAs) and 97 abbreviated
new drug applications (ANDAs) from
multiple applicants, effective July 8,
2011. The document indicated that FDA
was withdrawing approval of the
following three ANDAs after receiving a
request from the ANDA holder, A.H.
Robins Co., c/o Wyeth Pharmaceuticals,
Inc., P.O. Box 8299, Philadelphia, PA
19101–8299: ANDA 086661,
DONNATAL (phenobarbital,
hyoscyamine sulfate, atropine sulfate,
scopolamine (HBr)) Elixir; ANDA
086676, DONNATAL (phenobarbital,
hyoscyamine sulfate, atropine sulfate,
scopolamine (HBr)) Tablets; and ANDA
086677, DONNATAL (phenobarbital,
hyoscyamine sulfate, atropine sulfate,
scopolamine (HBr)) Capsules. Before
withdrawal of these ANDAs became
effective, PBM Pharmaceuticals, Inc.,
acquired the rights to the ANDAs and
informed FDA that it did not want them
withdrawn. Because the basis for
withdrawal would have been a request
from the ANDA holder and the request
was timely withdrawn, the approval of
ANDAs 086661, 086676, and 086677 is
still in effect.
