1. General Information General Information
1.1 Legislation Concerning the Use of Substances in Annex I
Article 7, point 1, pursuant to Council Directive 96/23/EC.
The legislation regarding the use of pharmaceuticals is stipulated in the Parliamentary Act
Governing the National Pharmacy Service and Medicinal Products, Act No. 54 from 1991, and the
Parliamentary Act Governing Food, Act No. 46 from 1985.
The Parliamentary Act Governing the National Pharmacy Service and Medicinal Products ensure
that only registered and/or approved pharmaceuticals (hereinafter, "medicines") may be imported
into the Faroe Islands. All said medicines shall be dispensed through the National Pharmacy
Service, which is a public, administrative authority regulated by the above-named authorising
legislation. The National Pharmacy Service utilizes the services of the Faroese Customs and Tax
Administration to assist in the control of the importation of medicines. The National Pharmacy
Service controls the monopoly for both the importation and the dispensing of prescribed medicines.
The use of said medicines is not only controlled by the Parliamentary Act Governing the National
Pharmacy Service and Medicinal Products, but also the Parliamentary Act Governing the National
Veterinary Service. Only authorised veterinarians may write prescriptions for medicines. Currently,
only two licensed fisheries veterinarians work within the aquaculture industry in the Faroe Islands.
The National Pharmacy Service may only dispense medicines prescribed by licensed veterinarians.
The Chief Veterinary Officer receives a copy of all prescriptions, and is able, therefore, to monitor
the various stock farms in the Faroe Islands.
The Chief Medical Officer, the Chief Veterinary Officer, and the Chief Pharmaceutical Officer
approve the various types of medicines that are used in fish farming and stipulate the withdrawal
time before harvest for the various medicines. Medicines that are not approved for fish farming may
not be used.
The National Food-, Veterinary-, and Environmental Agency (FVEA) receives a report, or copies of
the prescriptions, issued from the veterinarians, and are sent notices about harvesting of fish from
the factories. The factories are responsible for their own checks and for accepting only animals for
which the producer is able to guarantee that withdrawal times have been observed.
All stock farms are registered with the Agricultural Agency,
http://www.bunadarstovan.fo/pub/index.php?id=45 (see attachment 1).
They are subject to Parliamentary Act no.16, from 23 February 2001, concerning animal diseases,
prevention and combating diseases in animals and market supervision of animals and animal
extracts and the environmental protection laws, which the National Food-, Veterinary- and
Environmental Agency administers.
Moreover, pursuant to the Faroese Food Act (Act No. 46 from 1985), the National Food-,
Veterinary- and Environmental Agency conducts regular inspections of all fish processing plants in
the Faroe Islands. All fish processing plant are approved according to directive 91/493,
http://www.hfs.fo (see attachment 2).
1. General Information The fish processing plants label the packages of their products in compliance with labelling
regulations so that the contents can be traced back not only to the fish processing plant, but also to
the originating stock farm.

CHIEF PHARMACEUTICAL OFFICER: See Attachment 1, in the residue control plan 2002,
dated 19th March 2002. (FEA file 401-200100175)
CHIEF VETERINARY OFFICER: See Attachment 2, in the residue control plan 2002, dated
19th March 2002. (FEA file 401-200100175)
NATIONAL FOOD, VETERINARY AND ENVIRONMENTAL AGENCY (FVEA):
According to the COMMISSION DECISION of 23 JULY 1993, based on 93/494/EØF, the FVEA
Food Department is approved by the EU as a competent inspection authority with respect to fish
products.
The Food Department of FVEA employs four scientists, and six food and fish inspectors.
Inspections are made pursuant to the Faroese Food Act, which is similar to the former Danish Food
Act. See Attachment 3, in the residue control plan 2002, date 19th of March 2002. (FEA file 401-
200100175)
The Fish Disease Department of FVEA employs 3 scientists, and 1 fish inspector.
Inspections are made pursuant to the Parliamentary Act no.16 from 23 February 2001; concerning
Animal diseases and Departmental order no. 131, from 23rd December 2003, concerning disease-
preventative operations on stock farms, and no. 130, from 23rd December 2003, concerning
prevention and control of Infectious Salmon Anaemia, ISA.

The FVEA is under the Faroese Ministry of Industry and Trade. The Chief Veterinary Officer is
part of the Ministry of Industry and Trade.
See also the decision No. 1/2001 of the EC-Faeroe Islands joint committee (2001/127/EF),
Attachment 4, in the residue control plan 2002, date 19th of March 2002. (FEA file 401-
200100175).
1.3 National Tolerance Limits (MRL´s) for Authorised Substances and Environmental
Article 7, point 4, pursuant to Council Directive 96/23/EC. Detection limits are also tolerance limits for unauthorised types of veterinary medicinal products. For the authorised medicines, the Maximum residue limit (MRL) as defined in Annex I in Commission Regulation (EC) 2377/90 and later amendments, or, if such has not been defined, the provisional MRL, as defined in Annex III of the above-mentioned regulation, is regarded as the tolerance limit. For substances listed in Annex IV of the above-mentioned regulation, the detection of any residue is unacceptable. The tolerance limit for environmental pollutant is defined by the EU Decision 93/351/EEC. Heavy metal is defined in Commission Regulation (EC) No 78/2005 of 19 1. General Information January 2005, amending regulation (EC) No 466/2001 as regards heavy metals. Commission
Regulation (EC) No 199/2006 of 3 February 2006 amending Regulation (EC) No 466/2001 setting
maximum levels for certain contaminants in foodstuffs as regards dioxins and dioxin-like PCBs
For substances not embraced by the above-mentioned regulations and guidelines, a positive
detection will initiate an investigation and assessment of whether the findings needs to be
communicated to representatives of customers, or whether an action directed towards the producers
would suffice.
The detection limits using current analytical methods are shown in section 2.3.
If any samples are found to contain unacceptable residues of medicines or substances used in the
production, necessary corrective steps are taken immediately, both with respect to the fish from
which the sample was taken and the stock farm that raised the fish.
Corrective action is taken pursuant to §11 of the Food Act, which states:
It is not allowed to sell food for general use if it is suspected it will cause illness or poisoning, or if
the food, due to pathological changes, putrefaction, pollution, incorrect preparation or by other
means can [be] judged unfit for human consumption.
It should be noted that for medicines there have been no positive test results in the years 1987 –
2005.
There have been no reported incidences where the stipulated withdrawal times before harvest have
not been fulfilled. There have been no reported incidents of the use of unlawful substances.
1.4 Official Sampling Procedure in the Field, Including Information on How Samples Are
Secured After Collection
(Using Flow Charts) (Des 98/179/EC) Samples of fish and feed are collected in accordance with instructions given by National Food-, veterinary-, and Environmental Agency. Inspectors employed by FVEA, collect the samples from fish farms or processing plant. To comply with regulations governing inspections of stock farms and their use of medicines, inspectors from the National Food-, Veterinary- and Environmental Agency take samples as required. 1.4.1 Sampling Procedures The inspector visits the stock farm, accompanied by a representative from the stock farm. Fish are taken from the ring(s) that should be tested. Care is taken to obtain fish that do not appear to be diseased. The fish is, gutted. Or the inspector visits the processing plant, and takes a random sample of bled and beheaded fish and liver. Samples are taken from at least five fish from a designated ring. One sample consists of a small piece of each fish or its liver. Each test sample is placed in an impermeable plastic bag and well sealed. The sample bags are numbered 1, 2, 3, 4, 5, etc. Bagged samples of representative fish from the same ring are collected in one large plastic bag. 1. General Information This large plastic bag is labelled as follows: the test date, the name of the stock farm, the
registration number of the stock farm, the ring number, the sample number, the inspector's name,
the medicine(s) to be detected, i.e., oxitetracyclin: antibiotic.

The muscle and liver-samples are kept frozen at the laboratories until analysis. The feed is kept cool
< (4°C).
Rules concerning collection of official samples are laid down.

2.2 Details of Analysis Methods - Screening /Routine and Confirmation, with Action Levels
and Detection Limits
Article 7, point 5, pursuant to Council Directive 96/23/EC. 2. List of Official Laboratories 2.2.1 Screening of Stilbenes and Steroides in Fish The diethylstilbestrol assay is intended for qualitative estimation of diethylstilbestrol (DES), hexestrol (HEX), dienestrol (DIEN) and nortestosterone in urine, bile, feed, liver and fish. Fish samples are hydrolysed by enzyme, extracted, defatted and extracted. Hydrolysed substances are clean up with liquid extraction and solid phase extraction before derivatising and terminal points measuring with gas chromatography and mass spectrometry detection (GC-MS) 2.2.2 Confirmation of Stilbenes and Steroides in Fish In addition the confirmation process includes clean up on HPLC, before derivatising and analysing on GC-MS. 2.2.3 Screening test for the detection of Chloramphenicol in Fish muscle by ELISA Fish muscle is homogenised in ethyl acetate. After solvent change to iso-octane/chlorobutane, chloramphenicol is back-extracted into buffer and analysed by ELISA. 2.2.4 B 1 Antibacterial substances The analysis method used is method 6-G-001. The method is a bioassay and was developed at the Norwegian Directorate for Fisheries. Liver tissue is used for the assay. When residues of antibacterial substances are present in the animal, liver tissues usually contain higher concentration of the residue than muscle tissues. In special cases, muscle tissue can also be used. A piece of liver sample is placed on an agar medium containing a sensitive strain of bacteria. If present, antibacterial substances in the tissue will diffuse out into the medium and during the subsequent incubation the growth of the bacteria will be inhibited in a zone around the tissue. The strains of bacteria are: • E. coli to detect qiunolones (oxolinic acid, flumequine). pH in the medium is 7,2. Detection limit is 200 ng/g (µg/kg) • Bacillus cereus to detect tetracyclines and florfenicol. pH in the medium is 5,85. Detection limit is 200 ng/g (µg/kg) • Micrococcus luteus to detect sulfonamides. pH in the medium is 7,3. When residues are detected the sample is sent to the Fødevareregion Ringsted in Denmark for verification and identification. This is done with HPLC. 2.2.5 Screening for Ivermectin ans Emamectin in Salmon by LC/FLUORESCENCE The samples are extracted using anhydrous sodium sulphate and acetonitrile. Extracts are cleaned up by alumina chromatography followed by solid phase (SPE) using C18 cartridges. Residues of samples are derivatised with N-methylimidazole and trifluoroacetic anhydride and then analysed by liquid chromatography (HPLC) with fluorescence detector. Quqlity control and standards are run with each batch to ensure validity of results. 2.2.6 Determination of PCBs, Organochlorine and Pyrethorid pestiside residues in fish The pesticide is extracted from the sample matrix (10g) by blending the test portion with a solvent mixture of (300ml) acetone and hexane. 2. List of Official Laboratories The extract is then collected into a suitable vessel and reduced in volume by evaporation with
nitrogen. A portion of the extract is cleaned up using Gel Permeation Chromatography and Silica
Solid Phase Extraction. An internal standard is then added to the sample extract. Pesticide residues
are then determined in the sample extract by gas chromatography using mass spectrometry
detection and quantification.
The method is suitable for the determination of organochlorine, organ phosphorous, carbamate and
pyrethroid pesticide residues in fish. The limits of quantification for fish are: Organohlorine
pesticide residues: 10µg/kg.
2.2.7 Analytical methods for Organochloriniated pesticides and toxaphenénes congeners.
Method: E-448-A
2.2.8 Analytical methods for PCDD's/PCDF's
The measurements are done by high resolutions mass spectrometry (HRMS), which guarantees high
specificity and high sensitivity.

The aflatoxins are extracted from a grinded sample with acetonitrile-water (60+40, v/v) for one
hour. The extract is then filtered and diluted with PBS-buffer. A 50 ml portion of this diluted extract
is transferred to an immunoaffinity column. The aflatoxins are then eluted from the column with
totally 1.25 ml of pure methanol and finally diluted with 1,75 ml distilled water.
The aflatoxins is analysed on a reversed phase HPLC system with fluorescents detector and a Kobra
Cell. (ME05_018)

3.1 Description of Measures Taken by Competent Authorities When Residues Are Detected
Article 7, point 7-8, pursuant to Council Directive 96/23/EC. We have not detected any medicines in any samples of stock farm fish. No changes have occurred in allowable withdrawal times before harvest. Should a sample test be positive, this would be taken quite seriously. Necessary corrective steps would be taken immediately to protect the consumer. The affected stock farm would be forbidden to sell fish. These food products would be designated unfit for human consumption, pursuant to § 11 of the Food Act, which states: It is not allowed to sell food for general use if it is suspected it will cause illness or poisoning, or if the food, due to pathological changes, putrefaction, pollution, incorrect preparation or by other means can [be] judged unfit for human consumption. 3.1.1 Category A Substances: All fish from the sampled population will be declared unfit for human consumption and destroyed. (However, it may be necessary and prudent to conduct further testing to verify the initial test results.) 3.1.2 Category B1 Substances: If the fish are alive, they will be held for the requisite withdrawal time before harvest pursuant to regulations in force, and until no detectable residues of the medicines remain. If the fish from the sampled population have already been harvested, they will be declared unfit for human consumption and destroyed. The stock farms that produced the affected fish will be properly and thoroughly tested to determine the exact reasons for the positive result, prior to being granted permission to use medicines. Suitable arrangements will be made with the stock farm in order to ensure against repeat occurrences. 4. Scope of the Residue Plan Scope of the Residue Plan

Group of Residues Covered (as listed in Annex I). Breakdown of Substances Monitored in Each Group by Animal Species and Product (Table). Article 7, point 5, pursuant to Council Directive 96/23/EC. 4.1.1 The following changes have been made from the previous report: The survey of used medicines in 2004, from the Chief Pharmaceutical Officer was not carried out before September 2005, due to problems with the computer data. The survey of used medicines in 2004 and 2005 is stated in this report (see attachment 8) 4.1.2 The category A, substances: The likelihood to detect Stilbenes, Steroides or Chloramphenicol in salmon or trout, from aquacultur is very low. Therefor, and also based on previous experience and data from from the Chief Pharmaceutical Officer, we do have decided to pool 5 or 6 samples in each analysis. 4.1.3 Sulfonamides The inhibition zone against the sulfadimidiene sensitab is smaller than usual. The sulfonamid tesults has to be taken with some reservations, but referring to data from the Chief Pharmaceutical Officer, attachment 8, we dont have used any sulfonamid the last three years.
