Animal Drug Prosecutions -- Generally
|
Under the FDCA, Congress has comprehensively regulated animal
drugs. The
black market for these animal drugs includes both foreign-made
drugs
that do not comply with FDCA requirements, and drugs banned in the
United States. Targets in these investigations include smugglers,
distributors to veterinarians and livestock owners, and
veterinarians
who compound such drugs from smuggled raw or bulk ingredients.
The FDCA's regulation of animal drugs has two central aims. One
is
to ensure that veterinary drugs are both safe and effective for the
animals that receive them, because unsafe or ineffective drugs may
result in unnecessary economic loss to livestock owners. The other
aim
is to insure the safety of the nation's food supply. Unapproved
animal
drugs, or drugs that are used in an unapproved manner, may leave
dangerous chemical residues in food derived from treated animals.
Such
residues pose serious health risks to humans that ingest them.
The FDCA is structured to achieve its aims through two
complementary
approaches. One approach is to require that all "new animal drugs,"
21
U.S.C. § 321(v), be approved as safe and effective by FDA
before
being marketed for use. 21 U.S.C. § 360b. Virtually all drugs
intended for animal use are new animal drugs within the FDCA's
definition and thus are required to receive FDA's approval prior to
marketing. A drug lacking such approval is deemed to be adulterated
under the FDCA and may not be distributed in interstate commerce.
21
U.S.C. §§ 331, 351(a)(5), 360b. The other approach is to
require
that all drugs be properly labeled so that all users, including
laymen,
can use them safely and effectively. 21 U.S.C. § 352. A drug
that is
not properly labeled is deemed to be misbranded and may not be
distributed in interstate commerce. 21 U.S.C. §§ 331, 352.
FDA grants pre-market approval to a "new animal drug" only if
its
sponsor succeeds in demonstrating that the drug is safe and
effective
for its intended uses. To gain approval, the sponsor must submit a
"new
animal drug application" ("NADA") bearing extensive, scientifically
rigorous data covering a number of subjects. Such subjects include
the
ingredients and composition of the drug; the methods and controls
used
in producing the drug; and the extent to which foods derived from
animals treated with the drug may contain chemical residues that
pose
health risks to humans. 21 U.S.C. § 360b(b)(1). More
specifically, a
NADA must describe how the manufacturer proposes to measure
chemical
residues in food products derived from treated animals and must
describe
any restrictions on use of the drug necessary to keep such residues
at
safe levels.
Approval of an NADA, if granted, pertains only to those
particular uses
of the drug specified in the application (uses that would typically
be
confined to particular animals). 21 U.S.C. § 360b(a)(1). For
instance, an NADA showing safety and effectiveness of a particular
formulation for a disease condition in swine does not allow the
manufacturer to claim similar effectiveness for the disease
condition in
cattle. Due to the metabolic differences in species of animals,
each new
condition must be the subject of an approval. Moreover, FDA can
revoke
approval if, at a later time, evidence demonstrates that a drug is
not
safe or effective for the particular uses for which it has been
approved. 21 U.S.C. § 360b(e).
The extensive research, as well as laboratory and field
testing,
that is necessary to establish safety and efficacy is expensive.
Drugs
that are claimed to be the same as an approved drug, except for the
fact
they have been made by a different manufacturer, must still meet
the
rigorous NADA procedures. This requirement exists because it has
been
established that drugs, even though they may be of a similar
chemical
composition, do not necessarily work the same way. Drugs which have
not
been approved by FDA may be cheaper to obtain because they do not
bear
the overhead associated with the approval process. However, the use
of a
drug that lacks approval is accompanied by the very real threat
that the
drug may be harmful to the animal to which it is given, may not be
effective, and/or may leave harmful residues in the animal's meat,
milk
or eggs.
In addition to the premarket approval requirements for new
animal drugs,
the FDCA requires that all drugs, including veterinary drugs, be
properly labeled so as to assure their safe and effective use. This
means that all veterinary drugs must have adequate directions which
instruct users, including laymen, on numerous matters such as how
to
dispense the drug for the appropriate conditions and in the proper
manner, dose, frequency, and duration. Without such directions, the
use
of a drug could result in the drug not being effective or, even
worse,
harmful. A drug that is not properly labeled is misbranded. 21
U.S.C.
§ 352.
Investigations into the black market distribution of unapproved
drugs intended for use in food producing animals have revealed that
individuals and companies buy, at discount prices, foreign-made
drugs
that do not comply with the requirements of the FDCA, and then have
the
drugs smuggled or otherwise illegally imported into the United
States.
They are then sold either as contraband, i.e., as available
supplies of
animal drugs widely understood to be subject to a flat prohibition
on
use, or as "generic equivalents" of, or substitutes for, approved
animal
drugs.
In other words, the animal drug black market reflects two types
of
economic incentives. One type of incentive is the substantial
profit to
be made in simply bypassing FDA's pre-market approval process. In
response to this first kind of incentive, black marketeers sell
substitutes (supposedly chemical equivalents) for established,
approved
drugs. Typically, the substitutes contain active ingredients
smuggled or
otherwise unlawfully imported into this country from abroad. Not
having
been subjected to FDA scrutiny, and not having been compounded or
formulated for use under conditions meeting the high standards of
pharmaceutical science, the illegal substitutes are not assured of
having the same composition, purity, effectiveness, and safety as
the
approved formulations they purport to replace. This is true even
though
the approved formulations and illegal analogues may share active
ingredients or possess the same or similar chemical composition.
The
illegal products are, however, marketed at much lower prices than
the
approved drugs.
The second type of economic incentive is the large profit to be
made
in bringing to market drugs that are effective in treating
food-producing animals but that have been banned by FDA because of
health risks to humans or for some other reason. In response to
this
second type of incentive, black marketeers again typically smuggle
into
the United States or otherwise unlawfully import drug substances,
active
ingredients in bulk, from abroad.
The FDCA's prohibitions on the distribution in interstate
commerce
of misbranded or adulterated animal drugs reach quite far across
the
chain of distribution. For example, since the FDCA defines "drug"
to
include any article intended for use as a component of a "drug", 21
U.S.C. § 321(g)(1)(D), bulk ingredients destined for inclusion
in
any new animal drug are deemed to be adulterated and misbranded
unless
specifically within the coverage of an approved NADA governing all
aspects of the new animal drug, including identity of ingredients.
21
U.S.C. §§ 351(a)(5), 360b. Likewise, the term "new animal
drug"
includes pharmaceutical ingredients intended for use in an animal
feed.
21 U.S.C. § 321(w).
