UNITED STATES STANDARDS FOR ROUGH 
CELERY 
(Effective Sept. 1, 1932) 
GRADES 
U.S. No. 1 shall consist of well-trimmed stalks of 
celery of similar varietal characteristics which have 
fairly good heart formation and which are fairly well 
blanched‘ and not wilted or badly spread, and which 
are free from damage caused by growth cracks, hol- 
low crown, pithy branches, brown stems, seed stems, 
freezing, dirt, disease, insects, or mechanical or other 
means. (See Size for specifications on stalk length.) 
In order to allow for variations incident to proper 
grading and handling, not more than 10 percent, by 
count, of the stalks in any container* may be below 
the requirements of this grade, but not to exceed 
one fifth of this tolerance or two percent shall be 
allowed for decay. 
Unclassified shall consist of stalks of celery which 
are not graded in eonformity with the foregoing 
grade. 
SIZE 
Where celery is packed in standard containers the 
number of stalks shall be specified by numerical 
7 Celery which meets all the requirements of U.S. No. 1 
grade except as to blanching may be designated as U.S. No. 
1 Green celery. 
8 Application of tolerances: The tolerances specified for 
this grade are placed on a container basis. However, any 
lot of celery shall be considered as meeting the requirements 
of the grade, if the entire lot averages within the tolerances 
specified, provided that no sample from the containers in 
any lot is found to exceed the following amounts: For a 
specified tolerance of 10 percent, not more than 1% times 
the tolerance shall be allowed in any 1 package. For speci- 
fied tolerances of 5 percent or less, not more than double 
the tolerance shall be allowed in any 1 package.
