0 Foreword  
 
Cuttlefish and squid  are marine molluscs of the class Cephalopoda with eight arms and two tentacl es.  
 
This Tanzania Standard was prepared in order to ensure safety and quality of frozen cuttlefish and squid 
produced and/ or traded in Tanzania.  
 
In the preparation of this Tanzania Standard, considerable assistance was derived from IS 8076 - Frozen 
cuttle fish and squid - Specification  and stakeholders producing the product.  
 
In reporting the results of a test or analysis made in accordance with this Tanzania Standard, if the final 
value, observed or calculated is to be rounded off, it shall be done in accordance with TZS 4.  
 
1 Scope
