Monitoring Seafood Safety – SEIS / EEA RELEVANCE- Amund Maage National Institute of Nutrition and Seafood Research (NIFES), PO Box 176, Sentrum, N-5804 Bergen, Norway
NIFES today: • Totally about 150 employed • Additional Master-students Univ. of Bergen • Turnover 2008: 130 mill NOK
Ministry of Fisheries and Coastal Affair’s statutes for NIFES: “NIFES is the government’s centre of research and expertise within fish nutrition, healthy seafood and seafood safety. The basis for the institutes activity should be research and development, and include analyses, risk assessment, reference laboratory for analytical methods and assist with matters related to emergency preparedness. NIFES activity should support the work of the ministry and other governmental agencies in order to secure consumers safe and healthy seafood through the entire food chain from feed to fork, including the fisheries.”
NIFES MAIN WORK: FISH AS FOOD FOOD FOR FISH In some aspects Food Authorities and Environmental Authorities ca use the same data. NIFES is ready to give data to SFT/EEA/SEIS (but time prioriteis is on Food) Documentation and surveillance

MONITORING PROGRAMMES – SEAFOOD SAFETY (QUALITY), NORWAY-EEA RELEVANCE ? • NIFES - Seafood data, from 1994 (Ministry of Fisheries) - expanded basal studies, NSS-Herring • Programmes on behalf of the Norwegian Food Safety Authority • Research projects – different funding • Other relevant programmes- e.g. financed by the Ministry of Environment
NIFES’ SEAFOOD DATA AIM: • Document the content of contaminants in Norwegian seafood • Fulfil needs for independent data from food authorities, fisheries authorities, fishery and aquaculture industry and markets • Be able to establish time trends and uncover research needs • Data on www.nifes.no/seafooddata
August 2004: Searchable database established, available from link on www.nifes.no, of data from NIFES monitoring programmes. • So far 13 undesirable components and about 20 species have been included. • New data added every year – Also Part of Barents Sea Management Plan
PROJECT DESCRIPTION: Funding: Mainly through the Ministry, and some funding through FHF-fund Volume: about 3000 samples (94-08) from the 20 most economically important species (includes industrial species) Area: Barents Sea, Norwegian Sea and North Sea; and farmed salmon included (see map) Sampling: First years through Directorate of Fisheries Inspectors, but later during Institute of Marine Research (IMR), Bergen, research program/vessels contract fish fleet. Sampling Frequency: cod, herring, mackerel and salmon every year (since 2001), saithe and red fish every 3. year, and others like e.g. horse mackerel sampled every 7.-8 year. Substances analysed: e.g. dioxins, PCBs, +++ Future volume: Increasing…. Need for baseline data for several species (2007 plan 700 + samples)

Undesirable substances determined in wild fish from open seas and farmed fish • Inorganic compounds: • Mg, Al, Ca, V, Cr, Mn, Fe, Co, Cu, Zn, As, Se, Sr, Mo, Ag, Cd, Sn, • Ba, Hg, Pb, U • Species of As, Hg og Sn • Organic compounds: • Pecticides; HCB, HCH, DDT (Extended from 2005 incl. • toxaphene) • PCBs(28, 52, 101, 118, 138, 153,180) • Dioxines og dioxin like PCBs, (from 2002) • Polybrominated flame retardants (from 2004), • PAH (from 2005) • Fluorinated compounds (from 2007) • Radioactive isotopes: IMR-data, (Cesium137, technetium99)
CHEMICAL METHODS – development 2007/2008 – Accreditaion, LOQ • Increased number of: • Brominated compounds • Toxaphenes • Fluorinated compounds (PFOS) • More efficient extractions • New veterinary residues • Further arsenic speciation • Emerging substances……

Ongoing surveillance programmes on behalf of the Norwegian Food Safety Authority: • Control program on undesirable and desirable substances in complete feedingstuff, fishmeal and fish oil for farmed fish • Program on undesirable substances in blue mussel (Mytilus edulis) (EU- Directive 91/492 EEC and 79/923 EEC) • Program on drug residues and chemical undesirable substances in farmed fish (Directive 96/23 EC) • EU-program on dioxin and dioxin like PCBs in foodstuffs and feedingstuffs ( 2006) • * Processed Seafoods (herring, mackerel, smoked fish) • Oils • Metals & Brominated compunds in seafood • REPORTED TO NORWEGIAN FOOD SAFETY AUTHORITYEU (i.e. dioxins) • : ONGOING

Surveillance program - farmed fish Salmon (90 %) and trout (10 %) in accordance with 96/23/EC Cod will be included 1 sample for each 100 tons of fish produced (for 2006 ~6000 samples). Pooled samples (n=5) have been analysed (for 2006 ~1200 pooled samples).
29 parameters are tested Including: Results: Well below limits for those components where limits exists (e.g. dioxin, Pb, Cd, Hg, DDT). No antibacterial or antiparasitic components have been detected.
Surveillance programBlue mussel (Mytilus edulis) (EU directive 91/492) • 50 farming locations along our coast tested every year • Analyced for: • Metals (Cr, Cu, Zn, As, Ag, Cd, Hg, Pb ) • Organic pollutants • Microbiology • Algal counts (water) and toxins in shells Results: Little problems with microbiolgy and chemicals: Exeption might be inorganic arsenic Algal toxins causes problems

SEIS COMPATIBLE (www.nifes.no/Seafooddata) YES • Managed close to source • Collected once and shared • Available to public authorities • Enable fullfillment of legal reporting obligations • Readily accessable to end users • Use of common, free access-source software
SEIS CHALLENGES: • General aspects on factors influencing levels of contaminants in fish; size, age, trophic level, sex, season, maturity, point source • Challenge on the sampling station aspect: (Single fish move, schools move, change in patterns) We need to follow the fish • Interpretation of data – nutrition/enviroment • (Double reporting ? Sending data to more sources)
