Mineral Resources International and Trace Mineral Research (hereinafter “Minerals”) seek review of regulations promulgated by the Federal Drug Administration (“FDA”) under sections 343(q) and 343(r) of the Federal Food, Drug, and Cosmetic Act, 21 U.S.C. § 301 (Supp. Y1993). Minerals maintain that we have jurisdiction pursuant to 21 U.S.C. § 371(f) (1988 & Supp. V 1993). Minerals contend that the regulations violate their First and Fifth Amendment rights and the Administrative Procedures Act (“APA”), 5 U.S.C. § 706 (1988). We do not reach the merits of Minerals’ assertions because we lack original jurisdiction to review the validity of regulations promulgated pursuant to sections 343(q) and 343(r).

I.BACKGROUND

In petition numbers 94-9523, 94-9524, and 94-9525, Minerals challenge the validity of the health claim regulation, the nutrient content regulation, and the nutrition labeling regulation, respectively. 59 Fed.Reg. 395 (1994) (codified at 21 C.F.R. § 20, 101); 59 Fed.Reg. 378 (1994) (to be codified at 21 C.F.R. § 101.54-101.69); 59 Fed.Reg. 363 (1994) (to be codified at 21 C.F.R. § 101.36). These regulations were promulgated by the FDA pursuant to the Nutrition Labeling and Education Act of 1990 (“NLEA”), Pub.L. No. 101-535,104 Stat. 2353 (codified at 21 U.S.C. § 343(q), (r) (Supp. V 1993)) which amended the Federal Food, Drug, and Cosmetic Act. The NLEA added sections 343(q) and 343(r) to that Act.

II.JURISDICTIONAL CHALLENGE

On April 29, 1994, the FDA filed a motion to dismiss the petitions for lack of subject matter jurisdiction. The FDA asserts that the regulations Minerals challenge were promulgated under sections 343(q) and 343(r). The FDA argues that this court lacks jurisdiction' to review' a regulation promulgated pursuant to section 343(q) or 343(r), because these sections are not specifically set forth in 21 U.S.C. § 371(e) (1988 & Supp V. 1993),

In their opposition to the FDA’s motion to dismiss, Minerals do not dispute the FDA’s position that the regulations were promulgated under sections 343(q) and 343(r). Instead, Minerals advance discrete theories to support their contention that this court has original subject matter jurisdiction over their petitions. Minerals assert that section 371(f) expressly authorizes review of their petitions by this court. Further, Minerals contend that this court has original jurisdiction as a result of the 1990 amendment to 21 U.S.C. § 371(a) (1988). Additionally, Minerals insist that their petitions are properly before us because “the regulations in issue were promulgated not just pursuant to the NLEA but also pursuant to 21 U.S.C. § 371(a), the very statutory section that affords direct review in the United States courts of appeal.” (emphasis in original). Minerals also argue that this court has original jurisdiction over their petitions because the subject regulations affect foods for special dietary uses. Finally, Minerals maintain that public policy considerations justify the assertion by this court of original jurisdiction to review the regulations at issue in this matter.

III.ANALYSIS

Federal courts have limited jurisdiction. Henry v. Office of Thrift Supervision, 43 F.3d 507, 511 (10th Cir.1994). We must dismiss any matter when “it becomes apparent that jurisdiction is lacking.” Penteco Corp. v. Union Gas Sys., Inc., 929 F.2d 1519, 1521 (10th Cir.1991) (citations omitted); Tuck v. United Servs. Auto. Ass’n, 859 F.2d 842, 844 (10th Cir.1988), cert. denied, 489 U.S. 1080, 109 S.Ct. 1534, 103 L.Ed.2d 839 (1989). “Since federal courts are courts of limited jurisdiction, we presume no jurisdiction exists absent a showing of proof by the party asserting federal jurisdiction.” United States ex rel. Precision Co. v. Koch Indus., Inc., 971 F.2d 548, 551 (10th Cir.1992), cert. denied, — U.S. -, 113 S.Ct. 1364, 122 L.Ed.2d 742 (1993) (citations omitted). Minerals have the burden of demonstrating that their petitions are properly before this court. We address each of Minerals’ arguments under separate headings.

A. Original jurisdiction in this court pursuant to 21 U.S.C. § 371(f)

Minerals assert that we have original jurisdiction over their petitions pursuant to 21 U.S.C. § 371(f)(1). We disagree.

21 U.S.C. § 371(f)(1). provides that the United States Court of Appeals for “the circuit wherein any person affected resides or has his principal place of business” has original jurisdiction over challenges to regulations promulgated pursuant to the statutes expressly set forth in section 371(e)(1). Section 371(e)(1) does not expressly refer to regulations that are promulgated under sections 343(q) and 343(r). The scope of section 371(e) is explicitly limited to “any regulation under section 343(j), 344(a), 346, 351(b), or 352(a) or (h)....” 21 U.S.C. § 371(e)(1).

The FDA, pursuant to its general rule making authority established in section 371(a), promulgated the health claim regulation, the nutrient content regulation, and the nutrition labeling regulation. In 1990, when Congress enacted the NLEA and directed the FDA to issue the instant regulations, it did not instruct the FDA to promulgate section 343(q) or 343(r) pursuant to 21 U.S.C. § 371(e). We agree with the Second Circuit that when Congress wants regulations to be promulgated pursuant to the procedures set forth in 21 U.S.C. § 371(e), it has demonstrated that it knows how to do so. National Ass’n of Pharmaceutical Mfrs. v. FDA, 637 F.2d 877, 887 (2d Cir.1981). Minerals have not met their burden of demonstrating that section 371(f) confers original jurisdiction in this court to review regulations promulgated under sections 343(q) and 343(r).

B. Effect of the 1990 amendment of section 371(e) on this court’s jurisdiction over regulations promulgated under sections 343(q) and 343(r)

Minerals contend that Congress has conferred jurisdiction in this court over the challenged regulations notwithstanding the fact that sections 343(q) and 343(r) are not specifically set forth in section 371(e). Minerals assert that in 1990, when Congress enacted the NLEA, it chose not to amend section 371(e). Accordingly, Minerals assert that Congress “found nothing in Section 371 that needed to be changed and so [it] left that section untouched.” It would appear that Minerals believe that we can imply from the failure to modify section 371(e) that Congress intended to confer original jurisdiction on this court to review regulations promulgated pursuant to sections 343(q) and 343(r).

The only support Minerals cite for this proposition is Judge Malcolm Richard Wil-ke/s dissent in Independent Cosmetic Mfrs. and Distrib. Inc. v. United States Dep’t of Health, Educ. and Welfare, 574 F.2d 553 (D.C.Cir.), cert. denied, 439 U.S. 893, 99 S.Ct. 250, 58 L.Ed.2d 238 (1978). Minerals’ reliance on Judge Wilke/s dissent does not advance their cause. In his dissenting expression, Judge Wilkey pointed out that: “[t]here is no special statutory review procedure (i.e., court of appeals review) applicable to regulations promulgated pursuant to § 701(a).” Id. at 574 (Wilkey, J., dissenting).

Minerals’ theory is contrary to existing Supreme Court and Tenth Circuit authority. As noted above, federal courts can only exercise that jurisdiction conferred upon them by Congress. Henry, 43 F.3d at 511; Penteco Corp., 929 F.2d at 1521; Tuck, 859 F.2d at 844. We are “reluctant to infer new legislative provisions out of [Congressional] silence.” Quivira Mining Co. v. United States E.P.A., 728 F.2d 477, 483 (10th Cir.1984).

C. No original jurisdiction in this court over regulations promulgated under the FDA’s general rule making authority

Minerals claim that this court has original jurisdiction over their petitions because the FDA enacted the regulations that are the subject of their petitions pursuant to 21 U.S.C. § 371(a), which grants the FDA its general rule making authority. Minerals have failed to cite any case to support this theory.

The Second Circuit, in discussing which court has jurisdiction to review a regulation promulgated pursuant to section 371(a), reasoned that “the FDA’s general authority ‘to promulgate regulations for the efficient enforcement’ of the statute, must be challenged in the district court.” National Nutritional Foods Ass’n v. FDA, 504 F.2d 761, 772 (2d Cir.1974), cert. denied, 420 U.S. 946, 95 S.Ct. 1326, 43 L.Ed.2d 424 (1975). We agree. We do not have original jurisdiction over Minerals’ petitions based upon section 371(a).

D. Foods for special dietary uses

Minerals argue that we have original jurisdiction over their petitions because regulations promulgated under sections 343(q) and 343(r) affect “foods for special dietary uses,” which are governed by 21 U.S.C. § 343(j) (1988). Regulations promulgated under section 343(j) are subject to original review by this court pursuant to section 371(f).

The only support that Minerals cite for this proposition is a terse passage in their opposition to the FDA’s motion to dismiss which states as follows:

The foods in issue,■‘particular nutrient supplements designed for and used by those in the at-risk categories (who either have or are susceptible to having certain debilitating illnesses and conditions, including neural tube defects, cardiovascular disease and cancer) are special dietary use foods within the meaning of 21 U.S.C. § 343(j). See generally 21 U.S.C. § 350(c)(3)(A) [ (1988) ] and United States v. Undetermined Quantities of an Article of Drug Labeled as “Exachol”, 716 F.Supp. 787, 792 (D.C. [sic] S.D.N.Y.1989). Consequently, the statute does apply to vest jurisdiction over this appeal in this Court.

(emphasis in the original).

Minerals do not offer any argument in support of their theory that section 350(c)(3)(A) or Exachol can be interpreted to confer original jurisdiction over their petitions. Section 350(c)(3)(A) merely defines “foods for special dietary uses.” It does not contain any support for Minerals’ contention that regulations promulgated under sections 343(q) and 343(r) are subject to original review by this court. Exachol was decided in 1989, prior to the enactment of the NLEA in 1990. Exachol does not address the question whether this court has original jurisdiction over petitions challenging regulations promulgated under sections 343(q) and 343(r).

When the FDA promulgated the health claim regulation, the nutrient content regulation, and the nutrition labeling regulation, it was following the Congressional mandate to issue these regulations as authorized under sections 343(q) and 343(r). Assuming that sections 343(q) and 343(r) may incidentally affect foods for special dietary uses, only Congress has the power to confer jurisdiction on this court to review, in the first instance, challenges to regulations promulgated under these statutes.

E. Public policy does not support original jurisdiction over Minerals’ petitions

Finally, Minerals maintain that public policy warrants direct appellate review of their petitions. Minerals argue that we must adjudicate their petitions to prevent duplica-tive litigation in district courts across the nation. Minerals assert that judicial economy weighs against having a trial court adjudicate their petitions because their petitions raise legal issues which will have to be decided de novo in this court. Minerals’ public policy argument ignores the principle that this court lacks jurisdiction over a subject matter unless it is conferred by Congress. Henry, 43 F.3d at 511. Public policy considerations of judicial economy cannot be relied upon to expand our jurisdiction in the absence of express Congressional authority.

The petitions are DISMISSED.

The Secretary shall publish such proposal and shall afford all interested persons an opportunity to present their views thereon, orally or in writing. As soon as practicable thereafter, the Secretary shall by order act upon such proposal and shall make such order public. Except as provided in paragraph (2) of this subsection, the order shall become effective at such time as may be specified therein, but not prior to the day following the last day on which objections may be filed under such paragraph.
      (2) On or before the thirtieth day after the date on which an order entered under paragraph (1) of this subjection is made public, any person who will be adversely affected by such order if placed in effect may file objections thereto with the Secretary, specifying with particularity the provisions of the order deemed objectionable, stating the grounds therefor, and requesting a public hearing upon such objections. Until final action upon such objections is taken by the Secretary under paragraph (3), of this subsection, the filing of such objections shall operate to stay the effectiveness of those provisions of the order to which the objections are made. As soon as practicable after the time for filing objections has expired the Secretary shall publish a notice in the Federal Register specifying those parts of the order which have been stayed by the filing of objections and, if no, objections have been filed, stating that fact.
      (3)As soon as practicable after such request for a public hearing, the Secretary, after due notice, shall hold such a public hearing for the purpose of receiving evidence relevant and material to the issues raised by such objections. At the hearing, any interested person may be heard in person or by representative. As soon as practicable after completion of the hearing, the Secretary shall by order act upon such objections and make such order public. Such order shall be based only on substantial evidence of record at such hearing and shall set forth, as part of the order, detailed findings of fact on which the order is based. The Secretary shall specify in the order the date on which it shall take effect, except that it shall not be made to take effect prior to the ninetieth day after its publication unless the Secretary finds that emergency conditions exist necessitating an earlier effective date, in which event the Secretary shall specify in the order his findings as to such conditions.
