COUNCIL DIRECTIVE of 15 July 1991 laying down the health conditions for the production and the placing on the market of live bivalve molluscs (91/492/EEC)THE COUNCIL OF THE EUROPEAN COMMUNITIES, Having regard to the Treaty establishing the European Economic Community, and in particular Article 43 thereof, Having regard to the proposal from the Commission (1), Having regard to the opinion of the European Parliament (2), Having regard to the opinion of the Economic and Social Committee (3), Whereas, with a view to achieving the internal market and more especially to ensure the smooth operation of the common organization of the market in fishery products established by Regulation (EEC) No 3796/81 (4) as last amended by Regulation (EEC) No  2886/89 (5), it is essential that the placing on the market of live bivalve molluscs should no longer be hindered by disparities existing in the Member States in respect of health requirements; whereas this will enable production and placing on the  market to be better harmonized and bring about competition on equal terms while ensuring quality products for the consumer. Whereas Council Directive 79/923/EEC of 30 October 1979 on the quality required of shellfish waters (6) lays down that it is necessary to establish the health requirements to be observed for shellfish products; Whereas these requirements should be laid down for all stages during harvesting, handling, storage, transport and distribution of live bivalve molluscs in order to safeguard the public health of consumers; whereas these requirements shall apply equally  to echinoderms, tunicates and marine gastropods; Whereas it is important, should a health problem occur after the placing on the market of live bivalve molluscs to be able to trace back the establishment of dispatch and the harvesting area of origin; whereas it is therefore necessary to introduce a  registration and labelling system which will enable the route of a batch after harvesting to be followed; Whereas it is important that the public health standards for the final product must be specified; whereas, however, scientific and technological knowledge is not always advanced enough to lay down definitive solutions for certain health problems and  whereas it is therefore necessary, in order to guarantee optimal protection of public health, to set up a Community system to ensure rapid adoption and where necessary reinforcement of the health standards to safeguard human health from virus  contamination or other hazards; Whereas live bivalve molluscs obtained from harvesting areas which do not permit direct, safe consumption may be rendered safe by submitting them to a purification process or by relaying in clean water over a relatively long period; whereas it is  therefore necessary to define production areas from which molluscs can bet gathered for direct human consumption, or from which they have to be purified or relayed; Whereas it is primarily the responsibility of the producers to ensure that the bivalve molluscs are produced and placed on the market in compliance with the health requirements prescribed; whereas the competent authorities must, by carrying out checks and inspections, ensure that producers comply with those requirements; whereas the competent authorities must in particular submit harvesting areas to a regular control to ensure that molluscs from these harvesting areas do not  contain microorganisms and toxic substances in quantities which are considered to be dangerous to human health; Whereas control measures organized on a Community level must be introduced to guarantee the uniform application in all Member States of the standards laid down in this Directive; Whereas the rules, principles and safeguard measures established by Council Directive 90/675/EEC of 10 December 1990 laying down the principles governing the organization of veterinary checks on products entering the Community from third countries (7),  should apply to the case in question; Whereas in the context of trade between the Member States, the rules laid down in Council Directive 89/662/EEC of 11 December 1989 concerning veterinary checks in intra-Community trade, with a view to the completion of the internal market (8) as amended by Directive 90/675/EEC should also be applied; Whereas live bivalve molluscs produced in a third country and intended to be placed on the market in the Community must not qualify for more favourable conditions than those applied in the Community; whereas provision must be made for a Community  procedure for checking the conditions in third countries of production and of the placing on the market, in order to allow the Community to apply a common import system based on conditions of equivalence; Whereas, so that account may be taken of particular circumstances, derogations should be granted to certain establishments already operating before 1 January 1993 so as to allow them to adapt to all the requirements laid down in this Directive; Whereas, in the case of living animals that are edible whilst they are alive, a derogation should be made, with regard to the durability date, to the rules of Council Directive 79/112/EEC of 18 December 1978 on the approximation of the laws of the  Member States relating to the labelling, presentation and advertising of foodstuffs for sale (9) as last amended by Directive 91/72/EEC (10); Whereas provision should be made for the possibility of adopting transitional measures in order to cover the absence of certain implementing rules; Whereas the Commission should be entrusted with the task of adopting certain measures for implementing this Directive; whereas to that end, procedures should be laid down introducing close and effective cooperation between the Commission and the Member  States within the Standing Veterinary Committee, HAS ADOPTED THIS DIRECTIVE: CHAPTER I General provisionsArticle 1 This Directive lays down health conditions for the production and placing on the market of live bivalve molluscs which are intended for immediate human consumption or for further processing before consumption.

After purification or relaying, all the requirements set out in Chapter V of this Annex must be met; (c) can be collected but placed on the market only after relaying over a long period (at least two months), whether or not combined with purification, or after intensive purification for a period to be fixed in accordance with the procedure provided  for in Article 12 of this Directive, so as to meet the requirements under (a). Live bivalve molluscs from these areas must not exceed the limits of a five-tube, three-dilution MPN-test of 60 000 faecal coliforms per 100 g of flesh. 2.  Any change in the demarcation of production areas and the temporary or definitive closure thereof must be immediately announced by the competent authority to those affected by this Directive and in particular to producers and operators of  purification and dispatch centres. CHAPTER II REQUIREMENTS FOR HARVESTING AND TRANSPORTATION OF BATCHES TO A DISPATCH OR PURIFICATION CENTRE, RELAYING AREA OR PROCESSING PLANT   1.  Harvesting techniques must not cause excessive damage to the shells or tissues of live bivalve molluscs. 2.  Live bivalve molluscs must be adequately protected from crushing, abrasion or vibration after harvesting and must not be exposed to extremes of hot or cold temperature. 3.  Techniques for harvesting, transporting, landing and handling live bivalve molluscs must not result in additional contamination of the product, nor in a significant reduction in the quality of the product, nor in any changes significantly affecting  their ability to be treated by purification, processing or relaying. 4.  Live bivalve molluscs must not be re-immersed in water which could cause additional contamination between harvesting and landing. 5.  The means of transport used for transporting live bivalve molluscs must be used under conditions which protect the latter from additional contamination and crushing of shells. They must permit adequate drainage and cleaning. In the event of bulk transport over long distances of live bivalve molluscs to a dispatch centre, purification centre, relaying area or processing plant, the means of transport must be equipped in such a way as to ensure the best survival conditions  possible, and in particular must comply with the requirements laid down in Chapter IX, Section 2 of this Annex. 6.  A registration document for the identification of batches of live bivalve molluscs during transport from the production area to a dispatch centre, purification centre, relaying area or processing plant is issued by the competent authority upon  request by the gatherer. For each batch, the gatherer must complete legibly and indelibly the relevant sections of the registration document which must contain the following information: - the gatherer's identity and signature, - the date of harvesting, - the location of the production area in as precise detail as is practicable, - the shellfish species and quantity indicated in as precise detail as is practibcale, - the approval number and place of destination for wrapping, relaying, purification or processing. The registration documents must be numbered permanently in sequence. The competent authority must keep a register indicating numbers of registration documents together with the names of the persons collecting live bivalve molluscs and to whom the  documents were issued. The registration document for each batch of live bivalve molluscs must be date-stamped upon delivery of a batch to a dispatch centre, purification centre, relaying area or processing plant and must be kept by operators of such  centres, areas or establishments for at least 60 days. However, if gathering is carried out by the same staff operating the dispatch centre, purification centre, relaying area or processing plant of destination, the registration document may be replaced by a permanent transport authorization granted by the  competent authority. 7.  If a production or relaying area is closed temporarily, the competent authority must refrain from issuing registration documents for that area and immediately suspend the validity of all registration documents already issued. CHAPTER III CONDITIONS FOR RELAYING LIVE BIVALVE MOLLUSCS The following conditions must be met: 1.  live bivalve molluscs must be gathered and transported in accordance with the requirements of Chapter II of this Annex; 2.  techniques for handling live bivalve molluscs intended for relaying must permit the resumption of filter-feeding activity after immersion in natural waters; 3.  live bivalve molluscs must not be relaid at a density which does not permit purification; 4.  live bivalve molluscs must be immersed in seawater at the relaying area for an appropriate period which must exceed the time taken for levels of faecal bacteria to become reduced to the levels permitted by this Directive taking account of the fact  that the standards of Chapter V of this Annex must be met; 5.  the minimum water temperature for effective relaying must, where necessary, be determined and announced by the competent authority for each species of live bivalve mollusc and approved relaying area; 6.  areas for relaying live bivalve molluscs must be approved by the competent authority.

IV.  Requirements for dispatch centres 1.  In addition to the requirements under Sections I and II, the following conditions must be met: (a) conditioning must not cause any contamination of the product; conditioning facilities must be used in accordance with procedures recognized by the competent authorities, with special regard to the bacteriological and chemical quality of the sea  water used in those facilities; (b) equipment and containers in the conditioning facilities must not constitute a source of contamination; (c) procedures for calibration of live bivalve molluscs must not result in additional contamination of the product or in any changes affecting the ability of the product to be transported and stored after wrapping; (d) any washing or cleaning of live bivalve molluscs must be carried out using pressurized clean sea water or potable water; cleaning water may not be recycled. 2. Dispatch centres must accept only those batches of live bivalve molluscs which are accompanied by the registration document referred to in Chapter II, section 6 of this Annex and coming from an approved production area, relaying area or purification  centre. 3. Dispatch centres must have their own laboratories or secure the services of a laboratory equipped with the necessary facilities for checking, inter alia, whether the molluscs comply with the microbiological standards of Chapter V of this Annex.  Laboratory facilities outside the centres must be recognized by the competent authority. However, these requirements do not apply to dispatch centres obtaining their molluscs exclusively and directly from a purification centre where they have been examined after purification. 4. Dispatch centres must keep the following data at the disposal of the competent authority: - results of microbiological tests on live bivalve molluscs from an approved production area or relaying area; - dates and quantities of live bivalve molluscs delivered to the dispatch centre and corresponding registration document numbers; - dispatch details. These data must be classified chronologically and preserved for a period to be laid down by the competent authority, but not less than three months. 5. Dispatch centres situated aboard vessels shall be subject to the conditions laid down in point 1 (b), (c) and (d) and in points 3 and 4. The conditions laid down in I and II shall apply mutatis mutandis to such dispatch centres although special  conditions may be laid down in accordance with the procedure laid down in Article 12 of this Directive. CHAPTER V REQUIREMENTS CONCERNING LIVE BIVALVE MOLLUSCS   Live bivalve molluscs intended for immediate human consumption must comply with the following requirements: 1.  The possession of visual characteristics associated with freshness and viability, including shells free of dirt, an adequate response to percussion, and normal amounts of intravalvular liquid. 2.  They must contain less than 300 faecal coliforms or less than 230 E. Coli per 100 g of mollusc flesh and intravalvular liquid based on a five-tube, three-dilution MPN-test or any other bacteriological procedure shown to be of equivalent accuracy. 3.  They must not contain salmonella in 25 g of mollusc flesh. 4.  They must not contain toxic or objectionable compounds occurring naturally or added to the environment such as those listed in the Annex to Directive 79/923/EEC in such quantities that the calculated dietary intake exceeds the permissible daily  intake (PDI), or that the taste of the molluscs may be impaired. In accordance with the procedure laid down in Article 12 of this Directive, the Commission shall determine the testing methods for checking the chemical criteria and the limit values applicable. 5.  The upper limits as regards the radionuclide contents must not exceed the limits for foodstuffs as laid down by the Community. 6.  The total Paralytic Shellfish Poison (PSP) content in the edible parts of molluscs (the whole body or any part edible separately) must not exceed 80 microgrammes per 100 g of mollusc flesh in accordance with the biological testing method - in  association if necessary with a chemical method for detection of Saxitoxin - or any other method recognized in accordance with the procedure laid down in Article 12 of this Directive. If the results are challenged, the reference method shall be the biological method. 7.  The customary biological testing methods must not give a positive result to the presence of Diarrhetic Shellfish Poison (DSP) in the edible parts of molluscs (the whole body or any part edible separately). 8.  In the absence of routine virus testing procedures and the establishment of virological standards, health checks must be based on faecal bacteria counts. Examinations for checking compliance with the requirements of this Chapter must be carried out in accordance with proven methods which are scientifically recognized. For the uniform application of this Directive sampling plans as well as the methods and analytical tolerances to be applied in order to check compliance with the requirements of this Chapter must be established in accordance with the procedure laid down  in Article 12 of this Directive. The effectiveness of the faecal indicator bacteria and their numerical limits as well as the other parameters laid down in this Chapter must be kept under constant review and, where scientific evidence proves the need to do so, be revised following the  procedure laid down in Article 12 of this Directive. When there is scientific evidence indicating the need to introduce other health checks or to amend the parameters in this Chapter for the purpose of protecting public health, such measures must be adopted in accordance with the procedure laid down inArticle 12. CHAPTER VI PUBLIC HEALTH CONTROL AND MONITORING OF PRODUCTION   A public health control system must be established by the competent authority in order to verify whether the requirements laid down in this Directive are complied with. This control system  must include: 1.  periodic monitoring of live bivalve mollusc relaying and production areas in order to: (a) avoid any malpractice with regard to the origin and destination of the live bivalve molluscs; (b) check the microbiological quality of the live bivalve molluscs in relation to the production and relaying areas; (c) check the possible presence of toxin-producing plankton in production and relaying waters and biotoxins in live bivalve molluscs; (d) check the possible presence of chemical contaminants, the maximum authorized level of which will be fixed, in accordance with the procedure laid down in Article 12 of this Directive, by 31 December 1992. For the purposes of points (c) and (d), sampling plans must be established by the competent authorities for checking such possible presence at regular intervals or on a case-by-case basis in the event of irregular periods of harvesting. 2.  Sampling plans as provided for in point 1, must in particular take account of: (a) likely variations in faecal contamination at each production and relaying area; (b) possible variations in production at relaying areas in the presence of plankton containing marine biotoxins. The sampling must be carried out as follows: (i) monitoring: periodic sampling organized to detect changes in the composition of the plankton containing toxins and the geographical distribution thereof. Information leading to a suspicion of accumulation of toxins in mollusc flesh must be followed  by intensive sampling; (ii) intensive sampling: - monitoring plankton in the growing and fishing waters by increasing the number of sampling points and the number of samples, and - toxicity tests using the molluscs from the affected area which are most susceptible to contamination. Placing on the market of molluscs from that area may not be re-authorized until new sampling has provided satisfactory toxicity test results; (c) possible contamination of the molluscs in the production and relaying area; If the result of a sampling plan shows that placing on the market of live bivalve molluscs may constitute a hazard to human health, the competent authority must close the production area, as regards molluscs concerned, until the situation has been  restored. 3.  Laboratory tests in order to check compliance with the requirements for the end product as laid down in Chapter V of this Annex. A control system must be established to verify that the level of marine biotoxins does not exceed safety limits. 4.  An inspection of establishments at regular intervals. These inspections must include in particular checks: (a) to verify whether the approval conditions are still being complied with; (b) on the cleanliness of the premises, facilities, equipment and on staff hygiene; (c) to verify whether the live bivalve molluscs are handled and treated correctly; (d) on the correct application and functioning of purification or conditioning systems; (e) on the ledger books referred to in Chapter IV section III, 12 of this Annex, (f) on the correct use of health marks. These checks may include the taking of samples for laboratory tests; the results of these tests are notified to the persons responsible for the establishments. 5.  Checks on the storage and transport conditions for consignments of live bivalve molluscs. CHAPTER VII WRAPPING 1.  Live bivalve molluscs must be wrapped under satisfactory conditions of hygiene. The wrapping material or container must: - not impair the organoleptic characteristics of the live bivalve molluscs, - not be capable of transmitting substances harmful to human health to the live bivalve molluscs, - be strong enough to give adequate protection to the live bivalve molluscs. 2.  Oysters must be wrapped with the concave shell downwards. 3.  All wrappings of live bivalve molluscs must be sealed and remain sealed from the dispatch centre until delivery to the consumer or retailer. CHAPTER VIII PRESERVATION AND STORAGE  1.  In any storing rooms, live bivalve molluscs must be kept at a temperature which does not adversely affect their quality and viability; the wrapping must not come into contact with the floor of the store room,  but must be placed on a clean, raised surface. 2.  Reimmersion in or spraying with water of live bivalve molluscs must not take place after they have been wrapped and have left the dispatch centre except in the case of retail sale at the dispatch centre.  CHAPTER IX TRANSPORT FROM THE DISPATCH CENTRE   1.  Consignments of live bivalve molluscs intended for human consumption must be transported wrapped as sealed parcels from the dispatch centre until offered for sale to the consumer or retailer. 2.  The means of transport used for consignments of live bivalve molluscs must have the following characteristics: (a) their interior walls and any other parts which might come into contact with the live bivalve molluscs must be made of corrosion-resistant materials; the walls must be smooth and easy to clean; (b) they must be suitably equipped to provide efficient protection of the live bivalve molluscs against extremes of hot and cold, contamination with dirt or dust, and damage to the shells from vibration and abrasion; (c) the live bivalve molluscs must not be transported with other products which might contaminate them. 3.  Live bivalve molluscs must be transported and distributed using closed vehicles or containers which maintain the product at a temperature which does not adversely affect their quality and viability. The parcels containing live bivalve molluscs must not be transported in direct contact with the floor of the vehicle or container but must be supported on raised surfaces or by some other means which prevents contact. Where ice is used in transporting consignments of live bivalve molluscs, it must have been made from potable water or clean sea water. CHAPTER X MARKING OF CONSIGNMENTS   1.  All parcels in a consignment of live bivalve molluscs must be provided with a health mark so that the original dispatch centre may be identified at all times during transport and distribution until retail sale.  Without prejudice to Directive 79/112/EEC, the mark must contain the following information: - the country of dispatch, - the species of bivalve mollusc (common name and scientific name), - the identification of the dispatch centre by the approval number issued by the competent authority, - the date of wrapping, comprising at least the day and the month. By way of derogation from Directive 79/112/EEC the date of durability may be replaced by the entry 'these animals must be alive when sold'. 2.  The health mark may be printed on the wrapping material or be put on a separate label which is then affixed to the wrapping material or put inside the wrapping. It may also be of a twist-tie or staple design; self-adhesive health marks must not be  used, unless they are not detachable. All types of health mark must be for single use only and may not be transferred. 3.  The health mark must be durable and waterproof, and the information presented must be legible, indelible and in easily decipherable characters. 4.  The health mark attached to consignments of live bivalve molluscs which are not wrapped in individual consumer-size parcels must be kept for at least 60 days by the retailer after splitting up the contents of the consignment.
