 0 foreword  
 
Cucumber is a creeping vine that roots in the ground and grows up trellises or other 
supporting frames, wrapping around supports with thin, spiraling tendrils. It is widely 
cultivated for its edible fruit  that are high in water content  at an immature stage near full 
size but before the seeds fully enlarge. The fruit of typical cultivars of cucumber is roughly 
cylindrical, but elongated with tapered ends and is eaten fresh, often in a salad . 
 
 
This Tanzania Standard was prepared in order  to provide guidance to cucumbers 
producers and traders as well as regulators, and to ensure safety and quality of the 
produce.  
In the preparation of this Tanzania Standard considerable assistance was derived from: 
UNECE standard FFV -15 CUCUMBER 2021 .  
 
In reporting the results of a test or analysis made in accordance with this standard, if the 
final value observed or calculated is to be rounded off, it shall be done in accordance with 
TZS 4 (see clause 2).  
 
1. Scope  
 
This standard specifies quality and safe ty requirements, methods of sampling and test  of 
cucumber varieties (cultivars) grown from Cucumis sativus  L. to be supplied fresh to the 
consumer.   Cucumbers for industrial processing  and gherkins are excluded.  
 
 
2. Normative references

4.1 General requirements  
 
In all classes, subject to the special provisions for each class and the tolerances allowed, 
the cucumbers shall be: 
 intact  
 sound;  
 clean ; 
 fresh in appearance, and firm ; 
 practically free from pests  and damage caused by them   
  free of bitter taste (subject to the special provision for Class II under clause 4.4.1.3 ) 
 free of  abnormal external moisture  
 free of any foreign smell and/or taste.  
Cucumbers shall be sufficiently developed but their seeds shall be soft.  
 
The development and condition of the cucumbers shall be such as to enable them  to: 
 withstand transportation and ha ndling  
 arrive in satisfactory condition at the place of destination.  
 
4.2 Classification  
Cucumbers are classified in three classes, as defined below:  
 
4.2.1 “Extra” Class  
Cucumbers in this class  shall be of superior quality. They shall be characteristic of  the 
variety and/or commercial type.  
They shall be: 
 well developed  
 well-shaped and practically straight (maximum height of the inner arc: 1 mm per 
10cm of length of the cucumber).  
 
They shall be free from defects, including all deformations and particularly those caused 
by seed formation, with the exception of very slight superficial defects, provided these do 
not affect the general appearance of the produce, the quality, the keeping quality and 
presentation in the package.  
 
4.2.2 Class I  
Cucumbe rs in this class  shall be of good quality. They shall be characteristic of the variety  
and/or commercial type . 
They shall be: 
• reasonably developed  
• reasonably well -shaped and practically straight (maximum height of the inner arc: 10mm 
per 10cm of length  of the cucumber).  
 
The following slight defects  may be allowed, provided these do not affect the  general 
appearance of the produce, the quality, the keeping quality and presentation in the 
package:  
 
• a slight defect in shape, but excluding that caused by  seed development  
• slight defects in colouring; but the light -coloured part of the cucumber, where it  touched 
the ground during growth, is not considered a defect  
 
• slight skin defects    
 
 
 
4.2.3 Class II   
 This class includes cucumbers that do not qualify  for inclusion in the higher classes but  
satisfy the general requirements specified in clause 4.1 . 
The following defects may be allowed, provided the cucumbers retain their essential  
characteristics as regards the quality, the keeping quality and presentation:  
 
 defects in shape, but excluding those by serious seed development; slightly 
crooked cucumbers having a maximum height of the inner arc of 20 mm per 10 cm 
of length are allowed  
 defects in colouring up to one third of the surface; but the ligh t-coloured part of the  
cucumber, where it touched the ground during growth, is not considered a defect  
 skin defects.  
 
Crooked cucumbers having a height of the inner arc of more than 20mm per 10cm of 
length are allowed, provided they have no more than sligh t defects in colouring and have 
no defects or deformation other than crookedness, and are separately packed.  
 
 
4.3 Provisions concerning sizing  
Size is determined either by weight or by a combination of diameter and length.  
 
Uniformity in size is compulsory for Classes “Extra” and I.  
 
To ensure uniformity in size between produce in the same pa ckage, one of the following 
two options should be applied:  
 
a) Sizing by weight  
: 
 In the package where the smallest cucumber weigh s 400g or more , the variation 
in weight  shall not exceed 150g  
 In the package where  the smallest cucumber weigh s between 180g and less than 
400g, the variation in weight shall not exceed 100g  
Cucumbers below 180 g should be reasonably uniform in weight.  
 
b) Sizing by dia meter and length  
The range in length shall not exceed 5cm, and cucumbers should be reasonably uniform  
in diameter.  
 
 
4.4 Provisions concerning tolerances  
At all marketing stages, tolerances in respect of quality and size shall be allowed in each 
lot for produce not satisfying the requirements of the class indicated.

II quality.  
 
 
 
4.4.1.2  Class I  
A total tolerance of 10%, by number or weight, of cucumbers not satisfying the 
requirements of the class b ut meeting those of Class II is allowed. Within this tolerance

Class II quality nor the general  requirements, or of produce affected by decay.  
 
4.4.1.3 Class II  
A total  tolerance of 10%, by number or weight, of cucumbers satisfying neither the 
requirements of the class nor the general requirements is allowed. Within this tolerance 
not more than 2% in total may consist of produce affected by decay or of produce with 
tips having bitter taste.  
 
 
4.4.2 Size Tolerances  
For all classes (if sized) ; a total tolerance of 10%, by number or weight, of cucumbers not 
satisfying the requirements as regards sizing is allowed.  
 
 
4.5 Provisions concerning presentation  
 
4.5.1 Uniformity  
The contents of each package shall be uniform and contain only cucumbers of the same  
origin, variety or commercial type, quality and size (if sized).
