Vitek Supply Corporation manufactured “premixes” for veal calves—that is, mixtures that feed companies and livestock growers add to animal feed. Certain premixes contained elenbuterol, avoparcine, zinc bacitracin or various nitrofurans. Some of these substances promote growth and increase meat-to-fat ratios; others treat and prevent scours (diarrhea). And they are all unapproved by the Food and Drug Administration (FDA), either for use in food-producing animals generally or veal calves specifically. Several of the drugs are carcinogens; one may lead to acute poisoning in humans; and another may increase human resistance to antibiotics.
Vitek smuggled these drugs into the United States with the help of its Dutch parent, Pricor B.V. In shipments from Pricor to Vitek, the companies either misdescribed the drugs in documents submitted to the United States Customs Service or failed to declare the substances altogether. The scheme began to collapse when an animal grower informed the government about the true content of Vitek’s products and when investigators found undeclared substances concealed in a shipment from Pricor. Eventually a jury convicted Vitek and its president, Jannes Doppenberg, of conspiracy to defraud Customs and the FDA, of smuggling or receiving smuggled merchandise and of distributing adulterated or misbranded animal drugs with intent to defraud or mislead.
On appeal, Vitek and Doppenberg challenge several decisions of the district judge, beginning with his refusal to suppress the fruits of the government’s search and ending with his application of the Sentencing Guidelines. The government also cross-appeals from the defendants’ sentencing. We affirm in all respects.
I. Search and Seizure
The warrant authorizing the search of Vitek’s premises permitted the seizure of (1) all tainted animal feed; (2) any and all misbranded drugs, to include elenbuterol and any of its derivatives; (3) any and all records from February 18, 1989, relating to the importation of merchandise and to the smuggling and illegal entry of tainted animal feed; and (4) any and all records from February 18, 1989, relating to the illegal entry and distribution of misbranded drugs in interstate commerce. The warrant further instructed that the evidence seized should indicate possible violations of 18 U.S.C. §§ 545 and 1001 and 21 U.S.C. § 331(a)—statutes prohibiting the smuggling and the distribution of misbranded drugs or adulterated food. The defendants assert the warrant lacked sufficient particularity and was not supported by probable cause. These are issues we review de novo.
See United States v. Navarro,
The Fourth Amendment requires that a warrant “particularly deserib[e] the ... things to be seized.” This requirement
*481
precludes the issuance of a warrant that permits a “general, exploratory rummaging in a person’s belongings,”
Coolidge v. New Hampshire,
The Vitek warrant is broad, but not impermissibly so.
See United States v. Vanichromanee,
The defendants argue that the warrant did not advise government agents how to distinguish between legal and illegal substances. But a warrant must explicate the items to be seized only as precisely as the circumstances and the nature of the alleged crime permit.
See Shoffner,
In light of the nature of Vitek’s crime, the instruction regarding the seizure of records also satisfied the requirements of the Fourth Amendment. Evidence of importing and distributing illegal substances is not likely to be confined to a single type of document. As the D.C. Circuit has noted, “specificity is even more difficult [when] evidence of the crimes can be found in almost every type of business document conceivable.”
United States v. Dale,
The warrant also was supported by probable cause. At the time the warrant was issued, the government had been informed that Vitek was importing and distributing animal feed tainted with clenbuterol. The government had also been informed that Pricor, Vitek’s Dutch parent, was shipping tainted animal feed to other customers in the United States. In a shipment from Pricor to Vitek, investigators had found hidden parcels containing oxytetraeycline hydrochloride, colistine sufaat [sic], furaltadone hydrochloride and liquid Baytril. Sutherland Aff. at para. 30. All the drugs were misbranded and had not been declared on Customs documents. Based on these facts, the government had probable cause to believe that Vitek had been importing unapproved and mislabeled drugs. The government also had probable cause to believe that Vitek was blending these drugs into premixes and animal feeds. In sum, we find no reason to invalidate the warrant that authorized the search of Vitek’s premises.
II. Evidentiary Issues
A. Prior Litigation in the Court of International Trade
The first of the defendants’ evidentiary challenges relates to the charge that they conspired to defraud the Customs Service and the FDA, in violation of 18 U.S.C. § 371. To prove its case, the government argued, in relevant part, that the defendants failed to pay certain duties to Customs. But after earlier civil litigation with Vitek in the Court of International Trade, the government had stipulated that certain shipments from Pricor to Vitek were duty-free. In the criminal trial against Vitek and Doppenberg, the government argued that these same shipments were part of a scheme to defraud Customs. When Vitek sought to admit the government’s prior stipulations, the district judge excluded this evidence pursuant to Federal Rule of Evidence 403, on the grounds that the stipulations would confuse the jury and cause undue delay. We review this ruling for an abuse of discretion.
See United States v. York,
The government made its stipulations in the course of litigating
Vitek Supply v. United States,
As the district judge recognized, admitting the government’s stipulations into evidence would have opened the door to a panoply of issues surrounding the litigation in the Court of International Trade. In order to digest the import of the stipulations, the jury would have had to consider various Customs classifications, whether the information before the Court of International Trade was accurate and sufficient, and whether certain sworn statements were truthful. The nature of the questions addressed by the Court of International Trade would have only compounded the difficulty of the jury’s task; the district judge candidly admitted that he did not “get a handle” on the documents the defendants sought to present to the jury until he had the benefit of oral argument. Tr. at 3642. This is not a simple case like
United States v. Fisher,
As a practical matter, we also question whether the evidence would have benefitted Vitek and Doppenberg. They argue that the stipulations were important because the jury would question how the defendants could have deceived the Customs Service with respect to shipments that the government had stipulated were duty-free. But after the jury heard all the facts relating to the stipulations, they would perceive the defendants as trying to ride the coattails of an earlier, successful deception. We doubt that this would have given the jury reason to acquit the defendants of a charge of conspiracy to defraud the Customs Service.
B. Testimony of the Defense Expert
The defendants further contend that the district judge erred when he declined to allow a defense expert to testify about the effects of avoparcine and zinc bacitracin. Part of the government’s ease depended upon its proving that these substances are drugs. Under 21 U.S.C. § 321(g)(1)(C), a substance is a drug when it is intended to affect the structure or function of the body, and is not food. A defense expert allegedly was prepared to testify that avoparcine and zinc bacitracin do not affect the body’s structure or function. The district judge did not allow the testimony because it was not sufficiently set forth in a summary the defendants submitted in response to a scheduling order. The defendants’ summary stated, “[The expert] will testify that avoparcine and zinc bacitracin are considered safe and effective as feed additives for calves and cattles.” Vitek argues that it was “implicit” in this summary that the expert would testify that the substances are feed additives, not drugs. But neither the district court nor the government should have to parse the summary of expert testimony, searching for subtle nuances and relying on uncertain inferences. We agree with the district court that the summary failed to give adequate notice that the expert would testify .that avoparcine and zinc bacitracin are not drugs.
It is well-established that in a civil case, a district judge has the discretion to exclude evidence as a means of sanctioning one of the parties for an inadequacy in its
*484
"case, such as the summary at issue here.
See, e.g., Mid-America Tablewares, Inc. v. Mogi Trading Co.,
We have not yet had to define the limits of the district court’s power to use the exclusion of evidence as a sanction in a criminal trial,
see Harvey,
C. The Daubert Hearing
At trial, an expert witness for the government testified that scientific testing had revealed that Vitek’s premixes contained illegal substances. Vitek and Doppenberg maintain that this testimony is inadmissible under
Daubert v. Merrell Dow Pharmaceuticals, Inc.,
In
Daubert,
the Supreme Court determined that, when a district judge is faced with expert scientific testimony, the judge must decide “whether the expert is proposing to testify to (1) scientific knowledge that (2) will assist the trier of fact to understand or determine a fact in issue.”
Daubert,
Before allowing the government’s expert to testify at trial, the district judge held a five-hour Daubert hearing to evaluate the scientific validity of the expert’s testimony. Vitek and Doppenberg assert that the district judge strayed beyond the bounds of Daubert when he analyzed the material presented at the hearing. Specifically, they argue that the district court did not assess whether the expert’s techniques were generally accepted, ignored error rates and placed undue emphasis on the qualifications of the government’s expert. 1 We disagree.
We first address the contention that the district judge failed to determine whether the techniques used to ascertain the content of Vitek’s premixes are generally accepted. All the chemical testing took place at a FDA laboratory, where analysts performed four procedures—fourier transform infrared spectrometry, gas chromatography/mass spectrometry, high performance liquid chromatography and electrospray liquid chromatography tandem mass spectrometry. Each of these procedures reveals a substance’s “spectrum” or “fragmentation pattern”—a sort of chemical fingerprint. Analysts then identify a substance by comparing its spectrum with spectra from known standard samples or from a computer library. These procedures, and the tools used to perform them, are widely used and generally accepted in the fields of analytical and forensic chemistry. See Tr. at 259394, 2603, 2606, 2613. Vitek and Doppenberg, however, argue that the district court did not inquire whether the procedures are generally accepted for the specific purpose of determining the content of animal feed. But we have suggested that when tests involve the application of well known instruments “to a particular and not-out-of the-ordinary application,” some of the
Daubert
factors may be worthy of less emphasis. See
Cummins,
The defendants further argue that the district court should not have allowed the government’s expert to testify because he was unable to identify’ the error rate of his testing methods. But the purpose of an inquiry into error rates is to determine whether tests are accurate and reliable.
See United States v. Pierre,
With respect to the defendants’ argument that the district court gave undue emphasis to the expert’s qualifications, it is true that the court misspoke when it stated that one of the “nonexclusive guideposts” set forth in
Daubert
is whether the expert is qualified. Tr. at 2725. In fact,
Daubert
did not include the expert’s qualifications in its list of pertinent considerations.
Daubert,
however, did not intend to set forth “a rigid or exclusive list.”
See United States v. Hall,
When the district court’s analysis is within the parameters of Daubert, we affirm its decision to admit scientific evidence unless the decision is manifestly erroneous. See
Cummins,
III. Jury Instructions
Counts Seven, Nine, Eleven, and Twelve of the indictment charged Vitek and Doppenberg with introducing misbranded drugs in interstate commerce in violation of 21 U.S.C. § 333(a)(2). Counts Eight and Ten charged the defendants with introducing adulterated drugs in interstate commerce, also in violation of § 333(a)(2). The indictment specified that the drugs were “adulterated” because they were “new animal drugs”they had not been approved by the FDA and recognized as safe and effective for then-intended use of promoting growth and feed efficiency in veal calves. In order to be guilty of Counts Seven-Twelve, the defendants had to have acted with “intent to defraud or mislead.” 21 U.S.C. § 333(a)(2). To act with this intent, Vitek and Doppenberg must have had “knowledge of the essential nature of the alleged fraud.”
United States v. Hiland,
*487 Vitek and Doppenberg argue that the district court failed to instruct the jury that the government was required-to prove such knowledge. 2 The district- court charged the jury, in relevant part,
To act with intent to defraud means to act voluntarily and intentionally to deceive or cheat. The intent to defraud may be established by proof that, with respect to the specific count in question, the defendant intended to deceive or cheat another person, a business entity, or a government agency. To act with intent to defraud a government agency means to act with the intent to interfere with or obstruct a lawful government function by deceit or trickery, or at least by means that are dishonest—
To act with the intent to mislead means to act voluntarily and intentionally to conceal a material fact and thereby create a false impression, or-' to omit or withhold information from a statement and thereby cause a portion of the statement to be misleading. An intent to mislead may be established by proof that the defendant intended to mislead a person, an entity with whom he was doing business, or a government agency.
Our review of these instructions “is limited to the determination of whether the jury was misled in any way and whether it had understanding of the issues and its duty to determine these issues.”
United States v. Dack,
Given the allegations against Vitek and Doppenberg, the government needed to show that the defendants: (1) knew they were distributing a “new animal drug”; and (2) knew their labeling omitted any mention of unapproved substances.
See Hiland,
IV. Sentencing
After four days of hearings, the district judge sentenced Doppenberg to 44 months of imprisonment for conspiring to defraud the FDA and Customs and for smuggling and receiving smuggled merchandise (Counts One-Six), and to 36 months of imprisonment for introducing misbranded and adulterated drugs into interstate commerce (Counts Seven-Twelve), to run concurrently. Doppenberg also received three years of supervised release for Counts One-Six, and one year of supervised release for Counts Seven-Twelve, also to run concurrently. In addition; he was ordered to pay a special assessment of $600 and a fine of $25,000. Vitek was placed on probation for four years and fined $350,000. Both defendants, and a co-conspirator who pleaded guilty, were made jointly liable for a restitution payment of $735,266.65. Of this amount, $29,452.65 was for duties owed to the Customs Service; the remaining $705,814 was for a meat processor that destroyed its calves upon learning that they had been fed Vitek’s tainted products.
These sentences satisfy neither the defendants nor the government. Both appeal from the court’s application of U.S.S.G. § 2F1.1, which captures the “intended, probable, or otherwise expected loss” from a defendant’s fraud.
United, States v. Schneider,
A. The Defendants’ Arguments
Vitek and Doppenberg contend that, for purposes of § 2F1.1, Swissland, the meat processor, has not suffered a “loss” and is not a “victim.” The definition of these two terms is a question of law that we review de novo.
See United States v. Barrett,
We also reject the assertion that Swissland was not a victim for purposes of § 2F1.1. As Vitek and Doppenberg point out, Swissland was not a victim unless it was in fact defrauded—i.e., unless it did not know that Vitek’s produpt contained a banned nitrofuran. To bolster their claim, that Swiss-land was a knowing consumer of Vitek’s tainted product, the defendants rely on the law of agency.
3
In
Barrett
we suggested that, under § 2F1.1, the knowledge of an agent is imputed to the agent’s employer when the agent is acting at least in part for the benefit of the employer.
See
The defendants gloss over several points that distinguish Shield’s connection with Swissland from the straightforward employer/agent relationship discussed in Barrett. Shields was not a simple agent of Swissland. Instead, he was the employee of one of Swissland’s independent contractors. As a general matter, an employer is less likely to be held vicariously liable for the acts of its independent contractors than for the acts of its employees. See Stephan D. Sugarman, A Restatement of Torts, 44 Stan. L.Rev. 1163, 1195 (1992). But it is not necessary for us to determine the import of AF & L’s independent contractor status, as there is yet another factual complication which convinces us that Shields’ knowledge cannot be imputed to Swissland. Shields had his own feed supply business, Fancy Calf, which was unconnected to AF & L and was not an independent contractor of Swissland. Fancy Calf, not AF & L, purchased Apple First Start from Vitek. Thus, strictly speaking, we cannot say that Swissland received Apple First Start from one of its independent contractors. And Shields was simply wearing too many hats— co-creator of Apple First Start, vice-president of AF & L, and proprietor of Fancy Calf—for us to impute his knowledge to Swissland with any degree of confidence about the fairness of the result. We therefore affirm the district court’s decision to include Swissland’s $705,814 loss in the § 2F1.1 calculation.
In applying § 2F1.1, the district court also included a $29,452.65 loss suffered by Customs. Vitek and Doppenberg, however, argue that under the decision rendered by the Court of International Trade,
Vitek Supply Co. v. United States,
*490 B. The Government’s Cross-Appeal
At sentencing, the government asked the district court to include the losses of Vitek’s competitors and downstream consumers in its § 2F1.1 calculation. The district court refused to do so because it would “involve too much conjecture and speculation” and “the evidence in this case is [in]sufficient [to provide] a firm foundation for such a finding.” Sen. Tr. at 210. While we review the definition of “loss” de novo, we review the district court’s factual determination regarding losses for clear error.
See United States v. Andersen,
With respect to competitor losses, the government first looked to other sellers of premixes for veal calves—Vitek’s direct competitors. The government assumed that these sellers suffered losses when feed companies and livestock growers purchased Vitek’s tainted premixes, and sought to use Vitek’s gain from its premix sales as a proxy for that loss. This approach is not without support; the application notes to § 2F1.1 allow a district court to use the defendant’s gain to calculate a victim’s loss when a more precise measure is unavailable.
See
U.S.S.G. § 2F1.1, comment (n.8);
Andersen, 45
F.3d at 221. But gain may be used only if “there is in fact a loss, and [the] use of the gain results in a ‘reasonable estimate of the loss.’ ”
Andersen,
.
The government has done nothing more than establish the mere fact that other companies sell premix. See Gov.’s Sent. Mem. at 7 (citing to an exhibit that refers to Qualitech, another premix company). It is true, as the government argues, that in Andersen we declined to "find a loss because we had no reason to believe that competitors were selling the same or similar products. See 45 F.3d at 221. But whether the defendant has competitors is the beginning, not the end, of the inquiry. Here, while there is proof that some customers knew the content of Vitek’s products, there is no evidence that the presence of illegal ingredients drew customers to Vitek from its competitors. And even if we assume that Vitek’s competitors suffered a degree of loss-—that at least some of Vitek’s customers would have gone elsewhere had Vitek’s premixes not contained illegal substances—the government has provided us with no means of determining whether Vitek’s gain is a reasonable estimate of that loss. Vitek’s conduct was not pervasively illegal; it sold legal products as well as illegal ones. We have every reason to believe that if Vitek had not sold illegal premixes, it would have sold similar, legal products. Presumably, then, in the absence of Vitek’s fraud, not all of its sales would have gone to other sellers. On the record before us, however, we have no method of estimating how many sales would have gone elsewhere. For example, we do not know how many competitors Vitek has. We do not know the market shares of any of its competitors, or, for that matter, Vitek’s market share for its illegal or legal products. We do not know whether purchasers of feed additives frequently change suppliers. In sum, we cannot even begin to determine whether Vitek’s gain was a reasonable estimate of its competitors’ losses. The district judge did not err when he refused to use Vitek’s gain as a proxy for the losses of its direct competitors.
The government also asserts that the district judge should have included the losses of another class- of “competitors”: upstream drug suppliers. There are legal drugs that promote growth and feed efficiency in veal calves and prevent scours. The manufacturers of these drugs competed with Pricor, Vitek’s Dutch parent. The government argues (and this is ironic, in light of our preceding discussion) that, if Vitek had not included unapproved substances in its premixes, it would have included similar, legal substances. Therefore, the government contends, upstream drug suppliers suffered a loss as a result of Vitek’s illegal activities. See Gov.’s Sent. Mem. at 6-7 and Ex. A. The *491 government again proposed using Vitek’s gain as a measure of these upstream losses; to this end, the government determined how much Vitek “marked up” the drugs it included in its premixes. In support of the theory that the district court should use Vitek’s gain as proxy for upstream losses, the government submitted a publication entitled “1993 Feed Additive Compendium,” which establishes that approved drugs serve the same purposes as the drugs used by the defendants. The government also submitted evidence that Vitek purchased one legal substance from Pfizer, Inc. But we have no means of estimating, among other things, whether Vitek’s mark-up on illegal substances is equivalent to the mark-up on legal substances. We do not know whether Vitek could have obtained some, or all, of the legal drugs from its parent company. As with direct competitors, the government simply has failed to provide evidence that enables us to determine the extent of upstream losses and whether Vitek’s gains are a reasonable measure of these losses.
Finally, the government argues that the § 2F1.1 calculation should include the losses of downstream consumers. Unlike Swissland, most of Vitek’s direct customers were aware that the premixes contained unapproved drugs. Therefore, as the government concedes, these customers were not defrauded and the defendants cannot be held hable for their losses. However, the government argues, at some point innocent purchasers consumed the meat of veal that had been treated with Vitek’s tainted products. The government contends that these innocent purchasers suffered a loss, which should be measured by Vitek’s gross sales of its tainted products.
This was the approach taken in
United States v. Marcus,
The marketing of a drug employing an unapproved and untested formula, when the modification presents the potential to affect the safety, therapeutic value, or bioequivalence of the drug, renders the drug of unknown efficacy and safety; the sale of a drug represented to possess FDA approval under those circumstances does not provide consumers with the benefit of their bargain---- Given the unchallenged finding that consumers would not purchase a drug of unknown safety and efficacy at any price, the district court correctly concluded that ... gross sales were the appropriate measure of the actual loss suffered by consumers____
Id. at 610. As this quotation indicates, the Fourth Circuit’s reasoning rests largely on the assumption that a knowing consumer would not pay anything for the product that the Marcus defendant sold.
In some cases, a product may be so inherently harmful that a court can confidently conclude that it is worthless. At oral argument, the government stated that knowing consumers would have left the meat from veal treated with Vitek’s products “rotting on the shelves.” Perhaps the government is correct. But perhaps it is not. People take a wide variety of health risks; for instance, the knowing ingestion of certain carcinogens can be considered almost commonplace. Maybe some purchasers would have risked consuming the meat. If so, the proper measure of the consumer’s losses would be the difference between what the consumer would have paid if she had all the facts, and the price the consumer actually paid. Cf. U.S.S.G. § 2F1.1 app. n. 7(a). The problem, of course, is that these issues can only be addressed by speculation. This is not a case like Marcus, where the district court made an unchallenged finding that consumers would not purchase the defendant’s product at any price.
We do not wish to minimize the conduct of Vitek and Doppenberg. The government’s basic proposition is correct: innocent purchasers did not receive the , benefit of the bargain when they purchased meat from veal calves treated with Vitek’s premixés. As we explained in
Andersen,
“The FDA is in the
*492
business of protecting the public____ [T]he defendants :.. caused harm to the public through their violations of FDA rules.”
. Here the district court denied the government's request for'such a departure. The government did not appeal from this ruling.
Notes
. In an argument that hardly merits discussion, the defendants contend that the district judge misapplied the concept of peer review. They argue that the district court decided that "there must have been peer review since the testing took place over the course of many months.” Appellants’ Br. at 46. However, review of the district judge’s oral comments makes clear that he believed that there had not been enough time for extensive peer review. And because the tests used well-established technology to detect the presence of unapproved substances, the district judge felt that peer review was less critical. Daubert encoúrages exactly this kind of flexibility-
. The defendants also contend that the district court should have instructed the jury that 21 U.S.C. § 333(a)(1), which does not require intent to defraud or mislead, is a lesser included offense of § 333(a)(2). But this argument does not warrant discussion, since the defendants did not request an instruction on lesser included offenses until after the government began its closing argument. Accordingly, the request was untimely and the district court had the discretion to reject it.
See
Fed.R.Crim.P. 30;
United States v. Watson,
. The defendants also argue that circumstantial evidence established that Swissland knew the true content of Vitek’s products. The district judge, however, was convinced that Swissland had been defrauded. Because we do nol find this conclusion clearly erroneous, we do not further discuss the circumstantial evidence.
