ANNOUNCEMENTS RELATING TO RICE QUARANTINE (NO. 55) 
RICE QUARANTINE AMENDED 
(Press notice) 
July 30, 1934. 
An amendment of the Rice Quarantine, No. 55, issued today and effective 
August 1, requires that foreign rice straw imported into this country must not 
be compressed in the bales to a density of more than 30 pounds per cubic foot, 
the Secretary of Agriculture has announced. Rice straw, used in broom making, 
must be sterilized at the time of entry by a steam process. In highly com- 
pressed bales the heat penetrates the interior of the mass so slowly that the 
bale cannot be effectively sterilized in a reasonable time. Recent tests by the 
Division of Control Investigations of the Bureau of Entomology and Plant Quar- 
antine indicate that in bales of a density of less than 30 pounds, penetiation 
Kt tS place rapidly enough to put effective treatment on a practical 
basis.
