ADMINISTRATIVE INSTRUCTIONS PRESCRIBING MIETHOD OF TREATMENT OF ORANGES,
GRAPEFRUIT, TANGERINES, AND MANILA MANGOES FROM MEXICO

Pursuantu to the authority conferred upon the Chief of the Bureau of Entomology
and Plant Quarantine by 319.56-2 of the regulations supplemental to the Fruit and
Vegetable Quarantine (Notice of Quarantine No. 56, 7 CFR 319.56), the follo-ing
h" administrative instructions are hereby issued to prescribe method of treatment which
will meet the treatment requirements imposed under 319.56-2 as a condition of the
issuance of permits for the importation from Mexico of commercially-sound oranges,
grapefruit, and Manila mangoes.

319.56-2g Administrative instructions prescribing method of treatment of
oranges, grapefruit, tangerines, and Manila mangoes. from Meyxico. (a) Conditions
for issuance of permits. (1) Either of the approved vapor-heat schedules of treat-
ment specified in paragraph (b) of this section will meet the treatment require-
ments imposed under 319.56-2 as a condition of the issuance of permits for (i) the
importation from Mexico of conmmercially-sound oranges, free of leaves and other
plant debris, or (ii) the importation from Mexico during the 5-month period begin-
ning November 1 and ending the following March 31, of commercially-sound tangerines,
with tight skins and free from air pockets or puffiness, and free of leaves and
other debris. ifs revised, effective November 20, 1952, 17 F.R. 108477

(2) The approved vapor-heat schedule of treatment specified in paragraph (b)
(1) of this section will meet the treatment requirements imposed under 319.56-2 as
a condition of the issuance of permits for the importation from Mexico of commer-
cially-sound grapefruit and Manila mangoes, free of leaves and other plant debris.
iAs revised, effective November 20, 1952, 17 F.R. 108477

(3) The treatment must be conducted in a heat-treating room approved by the
Bureau of Entomology and Plant Quarantine and must be conducted under the super-
vision of an inspector of that Bureau, who at all times shall have access to such
fruits while they are undergoing treatment.

(4) The Bureau will approve only those rooms which are properly constructed
and adequately equipped to handle and treat such fruits, at locations acceptable
to the inspector in areas where required supervision can be furnished. No treat-
ing plant will hereafter be approved until it is equipped with a self-recording
temperature and humidity indicator acceptable to the inspector.

(5) All handling in Mexico subsequent to treatment of such fruits intended
for shipment to the United States must be carried out to meet requirements satis-
factory to the inspector and under such supervision as he may deem necessary.

(6) All costs of construction, equipping, maintaining and operation of
treating rooms and those associated with prescribed post-treatment safeguards shall
be borne by the owner of such fruits, or his representative.

(7) Supervision at places contiguous to ports of entry where inspectors are
regularly stationed will be furnished without cost to the owner of the fruit, or
his representative.








(8) In cases where treating rooms are located in the interior of
Mexico, or at places removed from ports of entry where inspectors are reg-
ularly stationed, those in interest must make advance arrangements for
approval of the plant and for supervision, and furnish the Chief of the
Bureau of Entomology and Plant quarantine with acceptable assurance that
they will provide, without cost to the Ur-e. States Lepartment of Agricul-
ture, all salaries, tranr.porta.tion, per diet, and other incidental expenses
for the supervising inspectors, including the payment to the inspectors of
additional compensation for their services in excess of 40 hours weekly,
according to rates established for the payment of Bureau of Entomology and
Plant Quarantine inspectors. [As revised, effective December 11, 1953,
18 F.R. 81227

(9) In the tests and ex-periments so far conducted with the approved
treating schedules such fruits have not been injured. It is, however,
emphasized that ine:xe.ctness and carelessness in using the approved schedules
for vapor-heat treatment may result in injury to the fruit treated. In
authorizing the use of the treatment specified in paragraph (b) of this
section, the United States Department of Agriculture dces not accept re-
sponsibility for fruit injury.

(b) Vapor-heat method of trea.mcnt and approved schedules. In ap-
proved vapor-heat treatment the fruit is heated by saturated vapor at 1100F.
which in condensing cn the fruit gives up its latent heat. This latent heat
is essential in assuring mortality of eggs and larvae of the fruitflies
known to occur in Mexico and in raising the temperature of the fruit evenly
and quickly so as to prevent damage to the fruit. In practice in such treat-
ments the saturated vapor is accompanied by a fine water mist and air ad-
mixture. The fruit is cooled immediately after treatment, and no wax or
paraffin, either dry or in solution, is used until after the treatment has
been completed. Vapor-heat treatment is approved orly if the vapor con-
ditions within the heat-treating room, the manner of stacking the field
boxes containing the fruit in the room, and all other conditions affecting
the efficacy of the treatment are satisfactory, in the opinion of the
supervising inspector, to assure mortality of eggs and larvae of the fruit-
flies known to occur in Mexico. The following schedules of vapor-heat
treatment, when conducted in accordance with the principles stated above in
this paragraph and in paragraph (a) of this section, are approved:

(1) The tempe..-ature of the fruit ,hall be raised to O110F., at the
approximate center of the fruit, in a perl-d of 8 hours and shall be held
at that level during the following 6 hours. This method is adapted to
sterilization plants that do not have the capacity to increase the tempera-
ture of the fruit steeply at the beginning of the treating period.

(2) The temperature of the fruit shall be raised to 1100F., at the
approximate center of the fruit, in a period of 6 hours and she.ll be held
at tlat level during the following 4 hout s. The temperatL.re of the fruit
must be raised rapidly du:-ing the first 2 hours, after which it my be
gradually raised to 110o. in the following 4 hours.

These administrative inst-uctions shall be effective the 12th day of
September, 1950, and at that time shall supersede B. E. P. No. 542,
effective September 4, 19L5 (7 CFR 319.56-2g).

The foregoing administrative instructions merely restate a method of
treatment previously approved in administrative instructions now in effect
and further authorize a new alternative schedule for use of vapor-beat for
treatment of oranges which shortens the period of treatment and thereby
provides a less burdensome means than the one presently authorized by which
Mexican shippers of oranges may qualify their fruit for importation. Ac-
cordingly the foregoing administrative instructions relieve restrictions
now in effect. Research has disclosed moreover that this new alternative
schedule of treatment for oranges may be used without increasing the risk
of spread of injurious insects. In order to be of maximum benefit to such
shippers, such new alternative method should be made available as soon as
possible. Therefore, pursuant to section 4 of the Administrative Procedure
Act (5 U. S. C. 1003) it is found upon good cause that notice aL.d public
procedure on the foregoing administrative instructions are unnecessary,
impracticable, and contrary to the public interest, and since these in-
structions relieve restrictions they may properly be made effective under
said section 4 less than thirty days after their publication in the
Federal Register.
