Introduction
There are increasing demands for detailed information on the nature and origin of food products.
Traceability is becoming a legal and commercial necessity.
The ISO definition of traceability concerns the ability to trace the history, application, and location
of that which is under consideration and for products, this can include the origin of food materials
and non-food parts; thereof, the processing history and the distribution and location of the product
after delivery. Traceability includes not only the principal requirement to be able to physically trace
products through the distribution chain from origin to destination and vice versa, but also to be able to
provide information on what they are made of and what has happened to them. These further aspects of
traceability are important in relation to food safety, quality, and labelling.
The scheme specified in this International Standard does not demand perfect traceability, i.e. that a
particular retail product should be traceable back to a hatchery and or farm and batch of origin.
Pragmatically, it is recognized that mixing of animals or materials is often commercially necessary
at a number of stages in the distribution chains, e.g. in grading at first sale prior to sale and in the
processing of raw materials into products. As a result, there will be occasions where whole chain
traceability of materials and products is neither possible nor commercially practical. These limitations
are to be recognized and taken into consideration when auditing against this International Standard
and are not to preclude compliance so as to disadvantage, otherwise compliant operators. Where such
mixing necessarily occurs, the food business shall generate a trade unit or units only from the point that
identification of units is possible. The requirement for traceability is that the business records the IDs
of created or received trade units that can be input into each subsequently created unit, thereafter and
vice versa. The particular product or products are then traceable through the supply chain (as far as is
practical) to generate information on the maximum number of stages of the chain as possible.
Given the variety of molluscan products and of their distribution chains that operate within and between
different countries and varying legal requirements, the information specifications cannot itemise all the
information that may possibly be required in every situation. This International Standard provides a
generic basis for traceability. Flexibility is allowed for businesses to record further information in their
own non-standardised files, but keyed to the same unit IDs.
The information remains in the ownership of the food business that generated it, but is available when
required by law for the purposes of traceability (in the event of a food safety problem) or by commercial
agreement between businesses. The structure, names, and content of the information is standardised so
that it can be readily communicated from business to business through the distribution chains ensuring
common understanding of terms and meanings.
Commercial arrangements for businesses to communicate information through the distribution chains
are to be encouraged, particularly for the information desired by the trade to be visible at the various
transaction points in the chains, but that is not the subject of this International Standard.
Though this International Standard is designed with electronic representation and communication of
data in mind, the specifications can be met by paper systems.
INTERNATIONAL STANDARD ISO 18538:2015(E)
Traceability of molluscan products — Specifications on
the information to be recorded in farmed molluscan
distribution chains
1 Scope
This International Standard specifies the information to be recorded in farmed molluscs supply chains
(excluding cephalopods) in order to establish the traceability of products originating from farm-raised
molluscs. It specifies how molluscan products traded are to be identified and the information to be
generated and held on those products by each of the food businesses that physically trade them through
the distribution chains. It is specific to the distribution for human consumption of molluscs and their
products from farm through to retailers or caterers.
The types of businesses identified in this International Standard for farmed molluscan distribution
chains are the following:
— farming;
a) broodstock suppliers/natural seed collectors;
b) hatcheries and nurseries;
c) molluscan farm;
d) harvesting;
— depuration and shucking etc.;
— processors;
— transporters and store operators;
— traders and wholesalers;
— retailers and caterers;
— logistics including materials brought from other domains;
— feed production.
Any given molluscan distribution chain can be made up of some or all of the above components, but not
necessarily in the sequence listed.

5 Principle
The fundamental principle of chain traceability is that trade units (TU) shall be identified by unique codes
(UI). This code may be globally unique in itself (for instance, the GS1 SGTIN or EPC numbers) or it could be
unique in that particular scope only which means that it should be no other TUs in that part of the chain
that can have the same number. If the scope (the product type, the company, the chain, the sector, the
country, or similar) is assigned a globally unique number, the combination of the globally unique scope
number and the locally unique TU number shall constitute a globally unique identifier for the TU.
NOTE 1 The UTUI term is introduced to indicate a TU identifier which is or can be made globally unique.
Trade units (TUs) can be grouped together to make logistic units (LUs) or LUs can be grouped together
to make higher level LUs. A fundamental principle of chain traceability is that logistic units shall be
identified by a unique code. This code shall be a national code which can be globally unique in itself
(similar to the GS1 SSCC code) or it could be unique in that particular scope only, which means that
there should be no other LUs in that part of the chain that may have the same number. If the scope (the
product type, the company, the chain, the sector, the country) is assigned a globally unique number, the
combination of the globally unique scope number and the locally unique LU number shall constitute a
globally unique identifier for the LU.
NOTE 2 The ULUI term is introduced to indicate a LU identifier which is or can be made globally unique.
The key to the operation of this traceability scheme is the labelling of each unit of goods traded, whether
of raw materials or finished products, with a unique ID. This shall be done by the food business that
creates each unit. Businesses that transform units such as processors who convert the units of raw
materials received into the products dispatched shall create new units and shall give them new IDs.
As indicated above, the simplest way of implementing UTUIs and ULUIs is to use the GS1 SGTIN/EPC
and SSCC codes. This practice is recommended, but is not mandatory. The central principle behind this
International Standard is that businesses which create TUs or LUs should assign unique numbers to them.
Each of the food businesses that create or physically trade in those units throughout the distribution
chains from catcher through to retailer or caterer shall generate and hold the information necessary for
traceability. The information is to be held on paper or electronically, keyed to the unit IDs.
6 Requirements
6.1 Identification of the units traded
Businesses that bring in supplies of farmed molluscan products from outside of the domain of the
specifications and trade them onwards shall identify each unit traded and record associated information
elements as indicated in Table 3 to Table 12.
6.2 Recording of information
To distinguish between the different categories of information, all information elements are classified
as either “shall”, “should”, or “may” with definition (see Table 1).

including new elements in this category is low.
Businesses that physically trade in molluscan products shall generate and hold the required information
appropriate to the type of business for each of the units traded. The detailed information requirements
are tabulated in Table 2.

For the purpose of unique identification to establish an extendable framework for data element identification, each table
has been identified with a three letter alphanumeric code. This code plus three digits is used to give a unique number to each
data element.
The information specifications separately tabulate the information to be recorded by each of these
types of business. Some businesses may carry out the functions of more than one of the types listed,
for example, distribution businesses can act as wholesalers and as transporters in which case those
businesses shall record the relevant information requirements for each of the functions carried out.
NOTE 1 This International Standard is limited in scope to the distribution for human consumption of molluscs
and their products. The molluscs information specifications are substantially the same from processing onward.
Pragmatically, it is recognized that some supplies of molluscan products and supplies of ingredients,
etc. will come from outside of the domain and may lack the required IDs and information records.
To accommodate this, a business that brings in molluscs and materials from outside of the domain is
required to generate and hold the key information necessary for the traceability of the units brought in
and if they are to be traded on to label those units with the required IDs.
NOTE 2 These specifications are designed with electronic representation and communication of data in mind, but
this is not a requirement when using the International Standard. The specifications can also be met by paper systems.
Note that the specification is for data to be generated, recorded, and stored at the respective link. For
all links, except “Breeders”, relevant data shall be generated in a previous link in the supply chain and
passed along with the trade unit/logistic unit.
NOTE 3 In these tabulations, there is no repetition of the information originally recorded to describe the units
created and their history, although businesses receiving those units later in the distribution chain will often need
some of that information. The information is keyed to the unit IDs and can be supplied by commercial agreement
between the businesses without having to re-input the data.
6.3 Controlled relaying and depuration
Bivalve molluscs concentrate contaminants from the water column in which they grow. These
contaminants may then cause illness to humans when the bivalves are eaten. Depuration is effective in
removing many faecal contaminants from shellfish. Depuration means the reduction of microorganisms
sand and other contaminants to a level acceptable for direct consumption by the process of holding live
bivalve molluscs for a period of time under approved controlled conditions in natural or artificial sea water
suitable for the process which may be treated or untreated. Relay systems (natural or in containers) and
land-based depuration establishments are efficient methods of achieving microbiologically safe bivalve
molluscs that are harvested from approved areas. Each registered facility that depurates or relays
molluscs should follow their quality management program and appropriate documentation should be
maintained for the process. The details of traceability of depuration process are shown in Table 5.
6.4 Broodstock supplier and natural seed collectors/suppliers
For the purposes of this International Standard, broodstock suppliers are considered to be
establishments/self help groups/farmer groups/fisherman that produce/collect broodstocks that are
supplied to hatcheries for further maturation and production of spat. They may carry out basic operations
like collection and maintenance of broodstock under good management practices in a sustainable way.
Prior to dispatch, broodstock suppliers can carry out their own operations or get it done through
approved agencies/laboratories for absence of OIE-listed diseases, quality, grading, etc.
The trade units created by broodstock suppliers can range from a few hundred to several thousand
passed into the hands of the next food business, i.e. hatcheries.
For the purposes of this International Standard, natural seed collectors/suppliers are considered to be
establishments that produce/collect seeds from natural sources that are supplied to farms for further
maturation. They may carry out basic operations like collection and maintenance of natural seed in a
responsible way to ensure sustainability.

6.6 Molluscan farms
For the purposes of this International Standard, molluscan farms are considered to be businesses that
receive molluscs/spat and keep them during the growing stage and dispatch the grown molluscan
spat/adults at required quantities to the processor/trader/retailer, etc.
The molluscan farms can change the nature of molluscan products by carrying out operations such as
feeding, grading, etc. Molluscan farms create new trade units that can range from a few tons to several
hundred tons passed into the hands of the next food business.
