 Foreword  
Development of  the East African Standards has been necessitated by the need for harmonizing requirements 
governing quality of products and services in the East African Community. It is envisaged that through 
harmonized standardization, trade barriers that are encountere d when goods and services are exchanged 
within the Community will be removed.  
The Community has established an East African Standards Committee  (EASC)  mandated to develop and 
issue East African Standards  (EAS) . The Committee is composed of representatives  of the National 
Standards Bodies in Partner States, together with the representatives from the public and private sector 
organizations  in the community .  
East African Standards are developed through  Technical Committees that are representative of key 
stakeholders including government, academia, consumer groups, private sector and other interested parties. 
Draft East African Standards are circulated to stakeholders through the National Standards Bodies in the 
Partner States. The comments received are discus sed and incorporated before finalization of standards, in 
accordance with the Principles and procedures for development of East African Standards . 
East African Standards are subject to review, to keep pace with technological advances. Users of the East 
African Standards are therefore expected to ensure that they always have the latest versions of the standards 
they are implementing .  
The committee responsible  for this document is Technical Committee EASC /TC 018, Nutrition and foods for 
special dietary uses.  
Attention is drawn to the possibility that some of the elements of this document may be subject of patent 
rights. EAC should  not be held responsible for identifying any or all such patent rights.

4.2 Internal quality control  and assurance  
4.2.1 Establishments should  develop, document and implement an internal quality system that will ensure 
the products will comply with the relevant national standards and/or regulation  
4.2.2 The establishment should  ensure while handling the premix/fortificants that:  
a) All premix/fortificants received to an establishment should  be accompanied by material safe ty data sheet 
and certificate of analysis including micronutrient profile and the shelf life of the premix/fortificants. This 
record should  be maintained for at least to shelf life of the product or as may be defined in the 
establishments’ documented infor mation.  
b) A proper schedule of movement of premix/fortificants to and from store is handled in a ‘First In First Out’ 
(in case of batches with same expiry date) and/or “first expiry first out” principle or any other principle that 
should  ensure the premix /fortificants do not keep long in the store. Records of these movements should  
be maintained.  
c) A record of dispatches made to the production, including at least but not limited to the type of 
fortificants/premix; date of production; shift (time); lot num ber where applicable and amount issued. A 
tabular module representation of this information is informatively annexed as Annex A.  
d) Any opened premix/fortificants containers should  be tightly closed to minimize exposure to air and light.  
e) The establishme nt should  ensure that expired premix/fortificant are not utilized and if any premix expires 
in the stores should  be disposed according to relevant regulations and records of its disposal should  be 
maintained for a period of not less than six (6) months aft er its disposal.  
4.2.3 The establishment should  ensu re that in the production site:  
a) the hygiene condition is in compliance with  EAS 39.

 b) the calibration of the equipment used in food fortification such as dosers, weighing scale is updated 
accordingly . Records of calibration should  be maintained. A schedule of inspection of the equipment at 
least on a weekly basis and record of finding should  be kept. A tabular module is attached as Annex B;  
c) periodically in a shift, the dosage should  be inspected /v erified to ensure that it is correct and records 
maintained; this should  apply in batch processing as well;  and 
d) a production log should  be kept indicating to the minimum time and date of production, amount of product 
produced, amount of premix used and product/premix ration and the name/officer responsible. A tabu lar 
module of this information as per Annex C . 
4.3 Planning and realization of safe products  
4.3.1 An establishment should  establish, document and implement a food management system that should  
ensure safe and quality production of fortified foods such as HACCP, ISO 22000.  
4.3.2 As the minimum the documented procedure should  indicate the following:  
4.3.2.1  Flow diagrams, process steps and control measures  
4.3.2.1.1  Flow diagrams should  be clear, accurate and sufficiently detailed. Flow diagrams should , as 
appropriate, include the  following:

b) any outsourced processes and subcontracted work;  
c) where raw materials, ingredients and inte rmediate products enter the flow;  
d) where reworking and recycling take place; and  
e) where end products, intermediate products, by -products and waste are released or removed.  
4.3.2.1. 2 The production/quality control team should  verify the accuracy of the flow diagrams by on -site 
checking. Verified flow diagrams should  be maintained as records.  
4.3.2.2  Control points  
The documented system should  indicate the control points within the production point where control measures 
will be required to ensure consist ency of the fortified products.  
4.3.2.3  Monitoring of the control points  
The food management system should  identify and document control measures (either operational prerequisite 
program or a critical limit) for each control point that should  be capable of  preventing, eliminating or reducing 
fluctuation on the dosage levels to acceptable factory range and should  be within the regulatory limits.  
4.3.2.4  Action s to be taken when critical limits are not met  
4.3.2. 4.1 Planned corrections and corrective actions to be taken when critical limits are not met  should  be 
specified . The actions should  ensure that the cause of nonconformity is identified, that the parameter(s) 
controlled at the control point is (are) brought back under control, and  that recurrence is pre vented.  
4.3.2. 4.2 Documented procedures should  be established and maintained for the appropriate handling of 
non-compliant products to ensure that they are not released until corrective action is taken.

 4.3.2.5  Verification of the food safety management s ystem  
Verification planning should  define the purpose, methods, frequencies and responsibilities for the verification 
activities. The verification activities should  confirm that the control measures are working and new critical 
points (if any) are documen ted and appropriate control measures applied.  
5 External quality control  
5.1 General requirements  
5.1.1 Establishments producing fortified food products should  be visited for inspection with intent to ensure 
compliance to regulatory limits as established.  
5.1.2 These visits should  be carried out at least twice in a year and more frequent where the laboratory test 
result(s) consistently fails to comply with the regulatory limits.  
5.1.3 These inspection visits may be pre -arranged or impromptu to an establishm ent. 
5.1.4 During the inspection the inspector should  be expected to the minimum confirm that the establishment 
is implementing the documented food system, confirm that all the records required by this standard are 
generated and documented according to the  establishment’s policy. A detailed report of inspection should  be 
generated and documented in accordance with the institutions procedures.  
5.2 Sampling   
5.2.1 An inspector on each visit should  sample the fortified food products for purposes on analysis in  an 
external laboratory.  
5.2.2 The samples should  be collected in amber glass bottles or similar appropriate containers drawn from 
the production line at intervals not less than 15 min from a particular point in the line.  
5.2.3 The sample size should  be fo ur (4) bottles of 200 g each, drawn at intervals described in 6.2.2. The 
samples should  be delivered to the testing laboratory for compositing before analysis. The firm being 
inspected may draw parallel samples and composite for their own internal analysis . 
5.2.4 The inspector may draw more than four samples if he/she deems it necessary.  
5.2.5 In the case of points of entry and at market level, sampling of fortified fo ods and premixes, should be 
done in accordance  with either ISO 5555,  EAS 900  or CAC/GL 50.  
5.3 Analysis  
5.3.1 The samples submitted should  be composited and a representative sample drawn from the composite 
in accordance to the methods of analysis being used.
