MURPHY, Circuit Judge.

      In 2011 Compart's Boar Store (Compart), a producer of breeding swine,
intended to export over three hundred pigs to China. China suspended all imports
from Compart, however, after it was notified by the United States government that

District of Missouri, sitting by designation.
the test results from a small set of the blood samples were "inconclusive" for Porcine
Reproductive and Respiratory Syndrome virus (PRRSv). Compart subsequently
brought a negligence suit against the United States under the Federal Tort Claims Act
(FTCA). The district court2 dismissed Compart's action for lack of jurisdiction after
concluding that it fell within the FTCA's discretionary function exemption. Compart
appeals and we affirm.

                                          I.

       The export of pigs to China is governed by the Quarantine and Health
Requirements of the People's Republic of China for Swine Exported from the United
States (China Protocol). Under the China Protocol the National Veterinary Services
Laboratories (NVSL) must test pigs prior to their export to China for PRRSv, a viral
disease which can cause pigs to have spontaneous abortions, pneumonia, lethargy,
and lack of appetite. NVSL is overseen by the Animal and Plant Health Inspection
Service which is an agency of the USDA.

       NVSL tests pigs for PRRSv using two immonufluorescent antibody (IFA) tests
and a virus isolation test. If the pigs pass the first IFA test they are isolated in a
quarantine facility for 30 days and tested again using another IFA test. Ten percent
of the quarantined pigs are also tested for PRRSv using a virus isolation test. NVSL's
procedure for virus isolation tests is set out in a document entitled Isolation of
Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) from Porcine
Specimens (hereinafter VISOP).

     This VISOP requires testing blood samples on two cell lines, known as SAM
and MARC cells. The cultures are then examined for cell damage over approximately

      The Honorable Patrick J. Schiltz, United States District Judge for the District
of Minnesota.

                                         -2-
seven days. If no cell damage is observed, the cultures are frozen and thawed and the
process is repeated. If no cell damage is observed for a second time, the cultures are
stained and examined for fluorescence. The presence of fluorescence ordinarily
indicates the presence of PRRSv. The VISOP provides the following guidance for
interpreting the stained cultures:

      If fluorescence is observed in any cultures inoculated with submitted
      specimens, and is comparable to fluorescence observed in the positive
      slides, and no fluorescence is observed in the negative controls, the
      specimen is reported as positive for PRRS virus isolation. If no
      fluorescence is observed in any but the positive control slides, the
      specimens are considered negative for PRRS virus isolation.

The VISOP provides no guidance, however, on what action to take when the cultures
do not appear positive or negative.

        In 2011 Ag World International Corporation secured a contract to export pigs
to China. After Chinese buyers selected over three hundred of Compart's pigs to be
included in the shipment, the pigs underwent PRRSv testing. During the first IFA
test, all of Compart's pigs tested negative for PRRSv. They were then placed in a
quarantine facility where they passed a second IFA test. During the virus isolation
test, NVSL did not observe any cell damage in either the MARC or SAM cells.
Nevertheless, a NVSL lab technician observed fluorescence in some of the stained
MARC cells. The fluorescence was unusual because it was not as bright as typical
positive slides and not as dark as typical negative slides. NVSL personnel then
conducted additional testing that yielded similar results. NVSL then issued a final
report stating that all PRRSv tests were negative with the exception of a few samples
whose results were "inconclusive." China subsequently suspended all swine imports
from Compart.

        Compart filed suit against the United States, alleging that NVSL was negligent
in testing its pigs for PRRSv and in reporting the results to China. The district court

                                         -3-
granted the government's motion to dismiss for lack of jurisdiction under Rule
12(b)(1). The court concluded that the discretionary function exemption to the
Federal Tort Claims Act (FTCA) barred Compart's claims. Compart appeals.

                                          II.

       We review de novo motions to dismiss for lack of jurisdiction under Rule
12(b)(1). Herden v. United States, 

, 1046 (8th Cir. 2013). The plaintiff
has the burden of proving subject matter jurisdiction. 

our court's
jurisdiction, we may look outside the pleadings. 

for clear error the
district court's "determination of disputed factual issues." Osborn v. United States,

, 730 (8th Cir. 1990).

       Sovereign immunity shields the United States and its agencies from suit absent
a waiver. FDIC v. Meyer, 

, 475 (1994). Under the FTCA the United
States has consented to be sued in tort "in the same manner and to the same extent as
a private individual under like circumstances." 28 U.S.C. § 2674. The FTCA
contains numerous exceptions to this waiver of sovereign immunity, however. E.g.,

If an exception applies, "the bar of sovereign immunity remains." Dolan
v. U.S. Postal Serv., 

, 485 (2006).

       One exception is the discretionary function exemption, which deprives courts
of jurisdiction over any claim "based upon the exercise or performance or the failure
to exercise or perform a discretionary function or duty on the part of a federal agency
or an employee of the Government, whether or not the discretion involved be
abused." 28 U.S.C. § 2680(a). The purpose of the exception is to "prevent judicial
second-guessing of legislative and administrative decisions grounded in social,
economic, and political policy through the medium of an action in tort." United
States v. Gaubert, 

, 323 (1991) (internal quotations omitted).



                                         -4-
       The discretionary function exemption applies if two requirements are met. See

–23 (1991). First, we must consider whether the suit
concerns "acts that are discretionary in nature, [that is] acts that involve an element
of judgment or choice." 

(internal quotations omitted). Government
employees act with discretion unless they are following a regulation or policy that is
"mandatory and . . . clearly and specifically define[s] what the employees are
supposed to do." C.R.S. ex rel. D.B.S. v. United States, 

, 799 (8th Cir.
1993). Second, we must determine whether the government acted or based its
decision "on considerations of public policy." 

(internal
quotations omitted). When the first step is satisfied, we presume that the
governmental action involved considerations of public policy. 

It is the
plaintiff's burden to rebut that presumption. 

.

       The district court correctly concluded that the challenged governmental action
here was discretionary. Governmental action is discretionary when a governmental
policy "predominately uses permissive rather than mandatory language." 

. Even when some provisions of a policy are mandatory, governmental
action remains discretionary if all of the challenged decisions involved "an element
of judgment or choice." Hart v. United States, 

, 1086 (8th Cir. 2011)
(internal quotations omitted). In this case, the VISOP predominantly uses permissive
rather than mandatory language. For example, the VISOP offers NVSL scientists
ranges for the amount of blood to be used in the tests, the time for initial incubation,
and the length of thaw times for the frozen samples. Moreover, the VISOP does not
provide any guidance on how to interpret stained slides for fluorescence or what to
do if these slides appear inconclusive for PRRSv—the challenged decisions here.

       Compart argues that our decision in McMichael v. United States, 

(8th Cir. 1985) compels the opposite conclusion. In that case, the plaintiffs claimed
that government inspectors failed to regularly perform a 51 step safety compliance
check. 

We concluded that the safety compliance check was mandatory,

                                          -5-
not discretionary, as it listed "a number of precise inspections to perform." 

A rote 51 step inspection list is not analogous to the VISOP which consisted of
mainly permissive guidelines that allowed NVSL personnel to use their judgment for
most testing and reporting decisions.

       The district court also correctly determined that Compart did not rebut the
presumption that NVSL PRRSv testing and reporting decisions was susceptible to
policy analysis. One of the hallmarks "of a decision susceptible to policy analysis is
one in which a federal employee must weigh or balance competing interests."

. The agency's decision here involved weighing several
competing interests when testing and reporting for the virus. Incorrectly reporting the
results as negative could have undermined China's confidence in the government's
PRRSv testing procedures. Yet incorrectly reporting the results as positive could
have resulted in harsh consequences for Compart and undermined United States pork
producers' confidence in NVSL. As the district court concluded, determining "what
to do in this sensitive situation plainly involved . . . considerations of public policy."

       Compart argues that the testing and reporting merely involved professional
scientific discretion, rather than considerations of public policy. It claims that this
case is similar to Lather v. Beadle County, 

(8th Cir. 1989), where the
plaintiff alleged that a government psychologist negligently evaluated him. In that
case we concluded that the psychologist's conduct did not involve considerations of
public policy because the treatment was "professional [and] nongovernmental." 

Compart's reliance on Lather is misplaced. There, the psychologist had a
"singular goal, i.e., providing appropriate medical care to a patient" and was not faced
with weighing competing interests like NVSL was required to do here. See 

(distinguishing Lather).

       Since NVSL's testing and reporting of Compart's swine was governed by
discretionary governmental procedures and susceptible to policy analysis, the

                                           -6-
discretionary function exemption precludes jurisdiction over Compart's negligence
claims.

                                         III.

      For these reasons we affirm the district court's dismissal of this action.
