Opinion for the Court filed by Circuit Judge EDWARDS.
This appeal is the by-product of a protracted dispute between Impro Products, Inc. (“Impro”) and the Department of Agriculture (“USDA”). In 1981, Impro filed suit claiming that USDA had improperly distributed reprints of an article that contained allegedly false and misleading information about an Impro product. The disputed article, published in 1970 in the American Journal of Veterinary Research, discussed a USDA study of the efficacy of a veterinary product manufactured by Impro. After hearing, the District Court enjoined USDA from releasing copies of the article and also ordered the Department to attach explanatory information to any other disseminated report on the USDA test of Im-pro’s product.
As a preliminary matter, there is reason to question whether there was any “final agency action” subject to judicial review under the Administrative Procedure Act (“APA”). However, even assuming that there was such agency action, we hold that review in the District Court was barred by the statute of limitations. Accordingly, we reverse the decision and order of the District Court and remand this case for further proceedings consistent with this opinion.
I. Background
Almost twenty years ago, in 1965, Impro applied to USDA under the Virus, Serum and Toxin Act of 1913, 21 U.S.C. §§ 151— 158 (1976) (“VST Act”), for a license to produce, ship and sell a veterinary product later named “Whey Antibody Blend.” The VST Act makes it unlawful to ship interstate any unlicensed virus, serum, toxin or “analogous product” intended for treatment of domestic animals. Id. § 158. Impro claimed the product improved the health and milk production of cows if properly administered.
Initially, the Veterinary Biologies Division of USDA issued a temporary license to Impro to market Whey Blend. The temporary license expired in September 1967 and, since that date, USDA has denied further Impro applications for a license to market Whey Blend. Impro has never sought judicial review of the denials of its license applications.
In 1966, scientists in the USDA Agriculture Research Service (“ARS”) reviewed the Impro license application, decided its supporting data were inadequate, and undertook their own study of the efficacy of Whey Blend. ARS scientists met with Im-pro representatives and worked out a protocol by which to test the product. Testing began in October 1966 at the Beltsville, Maryland, ARS facility, and was completed in December 1967. ARS scientists conclud
After receiving the May 8, 1981, correspondence, Impro filed this action. It alleged that the Beltsville test was not properly conducted and that the AJVR article contained false and misleading information about Impro’s product. Impro requested District Court review of USDA actions taken pursuant to the VST Act — which authorizes USDA to license products — and of actions taken in violation of its Fifth Amendment right to due process. Specifically, Impro sought a declaratory judgment that the test was unreliable and fallacious, and an injunction proscribing USDA’s distribution of, and reliance on, the Beltsville test and the AJVR article. The Government counterclaimed, arguing first, that Impro had sold its product interstate without a license, and that such sales should be declared a public nuisance and enjoined; and second, that such sales violated the VST Act and should accordingly be enjoined. The Government also entered an array of defenses, among them that neither the Beltsville test nor the subsequent publication of its results were “agency action” subject to review, and that any suit for judicial review was barred by the statute of limitations. See Impro Products, Inc. v. Block, No. 81-1284, slip op. at 5-6 (D.D.C. July 9, 1982) (Memorandum and Order), reprinted in J.A. 53-54.
In a series of rulings, the District Court addressed each of these issues. In deciding the issues pertinent to our review, the court first held that the VST Act makes certain action illegal but provides for no civil in-junctive relief. It therefore declined to imply such a remedy on behalf of the Government.

J.A. 38-46. Second, the court ruled that Impro’s complaint stated an actionable claim that was not time-barred. The court concluded that dissemination of the Beltsville test results was “agency action” subject to judicial review under 5 U.S.C. § 702,

On appeal, the Government challenges each of the rulings against it.
II. Discussion
A. The Existence of “Agency Action”
We begin our inquiry with a consideration of whether the agency’s behavior in this matter was properly subject to judicial review. The Administrative Procedure Act subjects to judicial review “final agency action” for which there is no other adequate remedy in a court. APA § 10(c), 5 U.S.C. § 704 (1982). For there to be “final” agency action, there must, of course, be “agency action.” A threshold question therefore is whether “agency action” has occurred. The APA defines “agency action” to include “the whole or a part of an agéncy rule, order, license, sanction, relief, or the equivalent or denial thereof, or failure to act.” APA § 2(g), 5 U.S.C. § 551(13) (1982). The District Court held that the agency’s decision to release the test results, made pursuant to 7 U.S.C. § 430, see note 2, supra, satisfied the statutory “agency action” language. Case law from this Circuit, however, suggests otherwise.
Thirty-five years ago, this court held, in
Hearst Radio, Inc. v. FCC,
The court in
Hearst Radio
first noted that the APA “does not provide judicial review for everything done by an administrative agency,”
Broad as is the judicial review provided by the Administrative Procedure Act, it covers only those activities included within the statutory definition of “agency action.” That definition obviously does not cover an act such as the publication of the Blue Book. It follows that the judgment of the District Court must be affirmed.
Hearst Radio,
Hearst Radio is not readily distinguishable from the case before us, and it leaves us with serious doubts as to whether USDA’s dissemination of the article amounts to reviewable agency action. 5 Both cases involve an agency decision to disseminate information it has gathered that is potentially harmful to the plaintiff. In both Hearst Radio and the case before us, moreover, the agency publication is alleged not only to be defamatory but also to be a knowing misrepresentation.
Despite its obvious relevance, we nonetheless have reason to question the continued validity of the
Hearst Radio
decision, particularly in a case such as this one in which there is a specific statutory authorization for dissemination of information.
6
The
Hearst Radio
doctrine has not been reconsidered carefully since 1948. During the thirty-five years since the issuance of the decision in
Hearst Radio,
the Supreme Court and lower courts have developed a more expansive interpretation of the term “agency action” than the one suggested by
Hearst Radio. See, e.g., FTC v. Standard Oil Co. of California,
With these considerations in mind, we believe that Hearst Radio may no longer be a viable precedent; we are therefore disinclined to find that no “agency action” has taken place. However, we need not reconsider Hearst Radio at this time because the statute of limitations requires reversal in this case. Accordingly, we will defer any reexamination of Hearst Radio to another day.
B. The Statute of Limitations
Assuming,
arguendo,
that the agency decision to disseminate the Beltsville test
First, two events that conceivably constitute final agency action occurred prior to 1975. The decision to disseminate the test results occurred prior to 1970, when the agency submitted the article to the AJVR for publication. This complaint was filed in 1981. It can hardly be argued that that “action” fits within the six-year limitations period. Nor does the agency’s decision to disseminate reprints of the article fit within that period, since it is clear that reprints were distributed as early as 1971. See Impro Products, Inc. v. Block, No. 81-1284, slip op. at 6-7 (D.D.C. Sept. 2, 1982) (Memorandum and Order), reprinted in J.A. 73-74. Since both events took place more than six years ago, review of both is barred by the statute of limitations. 9
Second, we have been directed toward no activity that occurred during the six years prior to filing that amounts to final agency action. Impro argues that final agency action occurred in 1981, when a USDA administrator responded to the last of numerous inquiries by Impro about USDA’s position on the Beltsville test and report, J.A. 88-89, and stated his belief that the agency’s actions were sound. J.A. 111. Impro therefore contends that the statute of limitations began to run in 1981. We disagree. Impro pursued its own informal routes of inquiry for ten years and then decided to characterize its 1981 letter to USDA as a request for a final resolution. Thus, it argues, the agency’s response to the 1981 letter constituted final agency action. This line of analysis is patently specious. For one thing, it is absurd to argue that the last date of inquiry is the relevant date for statute of limitations purposes. For another, it is surely a frivolous contention to suggest that USDA is somehow bound by Impro’s self-serving characterization of the 1981 letter as a request for a final ruling.
Plainly, the cause of action accrues when the “right to resort to federal court [is] perfected.”
Oppenheim v. Campbell,
We note, in addition, that Impro’s complaint also asserts that USDA violated its Fifth Amendment right to due process. The District Court did not entertain this assertion, apparently because it found that the APA provided ample means to give Impro the injunctive relief it sought. Because we cannot discern from the pleadings the precise nature of this constitutional claim, we remand to the District Court for further proceedings on that issue alone. In so doing, we emphasize that we take no position on the merits of Impro’s claim. 12
C. Implied Remedies on Behalf of the Government
USDA counterclaims that Impro is marketing its product, Whey Blend, without a license, and that the Government should be permitted to enjoin Impro from selling Whey Blend on the basis of an implied civil remedy under the VST Act.

The Act
Conclusion
For the reasons set out above, we reverse the decision of the District Court in part, affirm it in part, and remand this case for further proceedings.
So ordered.
Notes
. The District Court, however, found that procedures and objectives of the Beltsville test deviated from the project outline. Impro Products, Inc. v. Block, No. 81-1284, slip op. at 4-5 (D.D.C. Sept. 2, 1982) (Memorandum and Order), reprinted in Joint Appendix (“J.A.”) 71— 72.
. Under 7 U.S.C. § 430 (1982), the Secretary is authorized to test products and disseminate the results of the tests. The section provides:
The Secretary of Agriculture may purchase in the open market from applicable appropriations samples of all tuberculin, serums, antitoxins, or analogous products, of foreign or domestic manufacture, which are sold in the United States, for the detection, prevention, treatment, or cure of diseases of domestic animals, test the same, and disseminate the results of said tests in such manner as he may deem best.
.In fact, the District Court judge ruled first that both the conduct of the test and dissemination of the results were agency action. Subsequently he reconsidered that ruling and determined that the conduct of the test was not subject to review. Impro Products, Inc. v. Block, No. 81-1284 (D.D.C. July 28, 1982) (Memorandum and Order), reprinted in J.A. 60-67.
. The only difference is that the statutory words “whole or a part of an agency rule,” see p. 848, supra, have replaced the words “whole or part of every agency rule.” (emphasis added).
.The District Court relied on
Sears, Roebuck & Co. v. GSA,
. 7 U.S.C. § 430 (1982). In Hearst Radio, the court did not mention whether publication and dissemination of the Blue Book were authorized by statute.
. 7 U.S.C. § 427 (1982) sets forth the statute’s policy “to promote the efficient production and utilization of products of the soil . .. and to promote a sound and prosperous agriculture and rural life.”
.28 U.S.C. § 2401(a) (Supp. V 1981) provides in pertinent part: “Except as provided by the Contract Disputes Act of 1978, every civil action commenced against the United States shall be barred unless the complaint is filed within six years after the right of action first accrues.” As the language of § 2401(a) makes clear, the section applies to both equitable and legal claims.
See Saffron v. Department of Navy,
. Nor does each reissuance of the reprint start the statute of limitations anew. The decision to release reprints was made more than ten years ago, and Impro points to no evidence suggesting that a conscious, independent decision was made with any subsequent reis-suance.
. Of course, the statute may be tolled if plaintiff did not know, and could not reasonably have known, that it had been injured.
See Japanese War Notes Claimants Ass’n v. United States,
. Impro appears to argue that it is not bound by the constraints of the APA because its action is grounded solely on 28 U.S.C. § 1331 (Supp. V 1981). As a result, it contends, it need not prove “agency action” is implicated.; Brief of Appellee, p. 37. In making this argument, Impro overlooks the requirement of § 1331 that the action arise under the Constitution, laws, or treaties of the United States. Impro fails to point to any federal law, other than the APA, to be enforced, and it has offered, no grounds on which we could imply such a right to sue from any statute. Impro therefore is bound by the constraints of the APA.
. On remand, the District Court first must determine whether Impro’s constitutional claim passes the threshold test set out in
Bell v. Hood,
Third, if Impro’s claim falls within the statute of limitations, the District Court must then assess whether Impro in fact has suffered any damages. After a hearing, the District Court found that the AJVR article contains errors in its description of the test methodology but concluded nonetheless that the test results were misstated. This conclusion is difficult to fathom because the court pointed to no evidence that the article misconstrues the efficacy — or lack thereof — of Impro’s product. Indeed, Im-pro’s failure to present to USDA data suggesting otherwise, and its decision not to challenge the denial of its license application, counsel caution in determining whether Impro has been damaged by the errors in the article.
Finally, we note that the District Court’s finding that the article is false and misleading is in no respect dispositive of the question whether its dissemination amounts to constitutional defamation, if that in fact is the basis of Impro’s constitutional claim. Neither the elements of common law defamation,
see
Restatement (Second) of Torts §§ 558, 559 (1977), nor of constitutional defamation,
see Paul v. Davis,
.USDA filed two counterclaims. The first sought an injunction on an implied remedy. The other claim alleged that Impro’s interstate marketing of worthless products constituted a violation of the VST Act and a burden on interstate commerce, and sought to enjoin such sales as a federal common law public nuisance. The District Court pointed out that the nuisance claim was predicated solely on the alleged VST Act violations and that, since the VST Act did not authorize the Government to seek injunctions against violations, “the Government may not create that authority merely by styling its complaint as one in nuisance.”
