1932] SERVICE AND REGULATORY ANNOUNCEMENTS 13 
Cooling until the approximate center of the fruit reaches a temperature 
of 30° to 31° F. and holding the fruit at that temperature for 15 days. 
Such treatment is authorized in cold-storage plants approved by the Plant 
Quarantine and Control Administration and located either in Texas or in 
Northern and Western States not included in the Southern and Western States 
to which shipments of unsterilized fruit are prohibited. 
Fruit to be treated at localities outside the regulated area must be graded, 
packed in standard commercial containers, and shipped under special permits 
issued by the Plant Quarantine and Control Administration. Such permits will 
authorize movement only under ice in refrigerator cars and to designated 
cold storages. 
To provide necessary safeguards for movement to and handling at approved 
cold storages, those concerns designated to sterilize fruit are required to file 
an application and complete a written agreement with the Plant Quarantine 
and Control Administration. The administration will approve only those plants 
which are adequately equipped to handle and sterilize the fruit. 
Sterilization will be done under the supervision of representatives of the 
Plant Quarantine and Control Administration. These inspectors should at 
all times be given access to fruit while in process of sterilization. They will 
supervise the movement of the fruit from the car to and from the sterilizing 
rooms. 
No fruit which has been sent to designated storages for sterilization will 
be permitted to leave such cold storages except under permit issued by the 
inspector detailed to the plant concerned, and the issuance of such permits 
will be conditioned upon the sterilization of the fruit to the satisfaction of the 
inspector in manner and method authorized above. 
Railroads are authorized to move fruit, under permits for such movement 
issued to the shipper, from any part of the regulated area to designated cold 
storages under the usual storage-in-transit provisions of the railroad tariffs, 
but shall not transport such fruit from the said plants until a permit has been 
issued as provided in the foregoing paragraphs. 
In authorizing the movement of fruit sterilized in accordance with the above 
requirements, it should be emphasized that inexactness and carelessness in 
operation may result in injury to the fruit. It is understood that the depart- 
ment does not assume responsibility for fruit injury.

ADMINISTRATIVE INSTRUCTIONS 
Termination of Shipping Season for Texas Citrus Fruit 
[Issued under regulation 5, section A, Federal Quarantine No. 64] 
(Approved March 19, 1932; effective March 25, 1932) 
Under the Mexican fruit-worm quarantine regulations, it is ordered that 
the shipping season for citrus fruit from the counties of Willacy, Cameron, and 
Hidalgo in Texas will terminate at the close of March 25. The host-free 
period required by the Department of Agriculture will, for the year 1932, 
begin on the morning of March 26. 
This order modifies Administrative Instructions P. Q. C. A. — 326, issued on 
October 28, 1931. It becomes necessary owing to recent discoveries of in- 
festations of the Mexican fruit worm within the regulated area. Immediate 
eradication and clean-up measures are already under way and new steriliza- 
tion requirements have recently been issued. Citrus fruit will continue to 
be shipped from the regulated area until the date named, and permits will be 
issued by the United States Department of Agriculture under conditions 
which it is believed will prevent any risk of spread of the insect. The issuance 
of such permits will, however, cease for the season on the date named, except 
for fruit which has been removed from the trees prior to that time and is 
held in cold storage.

Acting Chief, Plant Quarantine and Control Administra'tion.
