Keeping fish fresh from sea to table is a complex process that demands strict temperature control, careful handling and up to date recordkeeping. Cold chain fish handling regulations ensure that seafood stays safe and of high quality throughout transport, storage and processing. Regulators such as the U.S. Food and Drug Administration (FDA), the European Union (UE) and national food authorities enforce specific temperature limits, traceability requirements and hygiene practices. Par exemple, the FDA’s Food Code requires cold foods to be held at 41 °F (5 °C) ou ci-dessous, while EU hygiene regulations mandate maintaining the cold chain for fishery products. This guide answers your questions about compliance, temperature rules, documentation and emerging trends in 2025.

What Are the Temperature Rules for Fresh and Frozen Fish?
Fresh fish must be kept as close as possible to 0 °C. The EU’s Regulation 853/2004 requires unpackaged chilled fishery products not immediately processed to be stored under ice and packaged fresh fish to be chilled to a temperature approaching melting ice. The Finnish Food Authority clarifies that unpackaged fish should be held between 0 °C et 2 °C (the “temperature of melting ice”), while packaged fresh fish and thawed products may be kept between 0 °C et 3 °C. A short term rise to 2–5 °C is acceptable but must be corrected quickly.
Pour poisson surgelé, the global benchmark is −18 °C (0 °F). The FSMA Sanitary Transportation Rule requires vehicles and equipment to maintain temperatures necessary to prevent unsafe food during transport. The EU hygiene regulation emphasises that frozen food must remain frozen during storage and distribution. Industry guides like Tempk summarise these rules: fresh fish should stay between 0 °C et 5 °C, while frozen fish must be held at or below −18 °C. The FDA Food Code standard of 41 °F (5 °C) for cold foods also applies to fish.
Temperature Categories and What They Mean for You
The table below summarises common temperature categories and their implications for fish quality and compliance.
| Plage de température | Regulatory Guidance | Impact on Fish Quality & Sécurité |
| 0 °C à 2 °C (32 °F à 35.6 °F) | Ideal for unpackaged fresh fish; must be stored under ice | Maintains optimum freshness and inhibits bacterial growth; required for most high value fresh fish. |
| 0 °C à 3 °C (32 °F à 37.4 °F) | Acceptable for packaged fresh fish and thawed products | Slightly higher temperature tolerated due to packaging; shelf life depends on packaging atmosphere. |
| 2 °C à 5 °C (35.6 °F à 41 °F) | Short term deviation category; FSMA Food Code requires cold foods to be ≤ 5 °C | Quality may decline; safe if corrective action is taken quickly. |
| ≤ −18 °C (0 °F) | Global standard for frozen fish; FSMA and EU require maintenance of freezing temperatures | Keeps fish fully frozen, preserving texture and nutrients; prevents histamine formation in species like tuna. |
| > 5 °C (41 °F) | Considered non compliant for cold foods | Increases risk of spoilage, bacterial growth and histamine; corrective action required. |
Practical Handling Tips
Pack fish in crushed ice or gel packs during transport and storage. NOAA recommends burying freshly caught fish in ice at 32 °F (0 °C) and placing them in coolers for transport. Replenish ice regularly and ensure drainage to prevent waterlogged flesh.
Use insulated containers and monitor temperature. Keep fish in the coldest part of the refrigerator near 32 °F and avoid leaving seafood at room temperature.
Separate raw and cooked seafood. To prevent cross contamination, store raw fish in leak proof containers below cooked or ready to eat items.
Avoid temperature abuse during thawing. Thaw frozen fish in the refrigerator or under cold running water, not on the counter, and cook it promptly.
How Do Regulatory Frameworks Govern the Fish Cold Chain?
NOUS. FSMA and Food Code
Le Loi sur la modernisation de la sécurité alimentaire (FSMA) transformed U.S. food safety regulation by shifting the emphasis from reaction to prevention. For cold chain fish handling, the key FSMA elements are:
Règle de transport sanitaire – requires shippers, loaders, carriers and receivers to use vehicles and equipment that maintain appropriate temperatures and prevent contamination. Written procedures must specify temperature conditions, monitoring methods and recordkeeping.
Règle de traçabilité des aliments (Section 204) – mandates additional recordkeeping for certain high risk foods, including some seafood products. Entities must keep Key Data Elements (KDE) for each Critical Tracking Event (CTE) and provide this information within 24 heures sur demande. The FDA proposed extending the original compliance deadline from January 2026 à juillet 2028.
Programme de vérification des fournisseurs étrangers (FSVP) – importers must verify that foreign suppliers meet U.S. normes de sécurité. Pour le poisson, this includes verifying proper cold chain management and documentation.
Analyse des risques et points de contrôle critiques (HACCP) – seafood processors must follow the Seafood HACCP regulation, identifying hazards (Par exemple, histamine formation, pathogen growth) and critical control points (Par exemple, storage temperature, conditionnement). Maintaining cold temperatures is integral to controlling these hazards.
EU Hygiene and Traceability Regulations
The EU’s regulatory framework is built on Règlement (CE) Non 852/2004 on the hygiene of foodstuffs and Règlement (CE) Non 853/2004, which sets specific requirements for fishery products. Les points clés comprennent:
Maintaining the cold chain – food that cannot be safely stored at ambient temperatures must remain at appropriate cold temperatures throughout production, transport et stockage. Pour le poisson, this means immediate cooling after catch and continuous refrigeration.
Storage under ice – unpackaged chilled fish must be stored under ice; packaged fresh fish must be chilled to a temperature approaching melting ice.
HACCP and Good Hygiene Practices – food business operators must implement HACCP and maintain records demonstrating compliance.
Traçabilité numérique – the EU’s fisheries control system was modernised in January 2024, making electronic catch declarations and digital traceability mandatory across the supply chain. Importers must use the CATCH system for catch certificates by January 2026.
Other International Standards and Certifications
Codex Alimentarius provides international guidelines on fish and fishery product hygiene, aligning with HACCP principles.
British Retail Consortium (CRB) et des aliments sûrs et de qualité (SQF) certification schemes require effective cold chain controls and traceability. Le 2025 update notes that these standards increasingly demand integration of IoT monitoring and digital records.
Marine Mammal Protection Act (MMPA) Import Provisions – from January 1 2026, les États-Unis. will prohibit imports of fish from fisheries lacking comparable marine mammal protection measures. While not strictly a cold chain rule, compliance may involve additional documentation and monitoring.
Why Does Traceability Matter for Cold Chain Compliance?
Traceability ensures that every fish can be tracked from catch to consumer. Robust records help identify sources of contamination, verify that temperature controls were maintained and support recalls when necessary. Dans 2025, traceability has become not only a regulatory obligation but also a market differentiator.
Combating Seafood Mislabeling
UN 2025 meta analysis of U.S. seafood found that approximately 39.1 % of sampled seafood was mislabeled, with species substitution accounting for 26.2 %. Mislabeling often involves substituting expensive fish with cheaper species, which can mask safety issues (Par exemple, histamine risk) and mislead consumers. Accurate labeling requires matching catch documentation, numéros de lots, and species identification through DNA testing. Maintaining cold chain temperatures helps preserve physical and genetic integrity, making identification easier.
Section FSMA 204: Éléments de données clés (KDE)
Under FSMA’s food traceability rule, businesses must capture and link KDEs—such as lot codes, product descriptions, harvest dates, and temperature readings—to each Critical Tracking Event (recevoir, transformation, expédition). These records must be provided to the FDA within 24 heures de demande. Digital systems simplify compliance by automating data capture and retrieval.
EU Digitalisation and Catch Certificates
L’UE 2024 reform mandates electronic recording and full digital traceability for all fishery products, including catch certificates, transport documents and processing records. From January 9 2026, importers must use the CATCH IT tool to submit catch documentation. Failing to provide verifiable records may result in import refusals or penalties. Effective traceability also supports consumer demand for sustainability and ethical sourcing.
Best Practices for Building a Traceable Cold Chain
Based on industry recommendations and Folio3 FoodTech’s guidelines for 2025, the following practices enhance traceability:
Accurate catch documentation – record date, temps, méthode de pêche, species and location immediately at harvest.
Unique batch identifiers – assign batch numbers, QR codes or RFID tags to each lot, updating parent child relationships when splitting or merging batches.
Standardised data formats – adopt GS1 coding and shared digital templates to ensure data compatibility across the supply chain.
Suivi en temps réel – use GPS, temperature sensors and blockchain to monitor product movement and environmental conditions.
Training and collaboration – educate all stakeholders on their role in traceability, provide digital tools and maintain open communication.
These practices reduce errors, speed up audits and help you meet both FSMA and EU traceability requirements.
What Equipment and Practices Ensure Safe Handling?
Véhicules, Containers and Temperature Monitoring
Under the FSMA Sanitary Transportation Rule, shippers must ensure that vehicles and equipment are suitable for maintaining product temperatures and preventing contamination. Camions frigorifiques, conteneurs isolés, gel packs and dry ice help maintain the correct temperature range. Modern fleets often incorporate Capteurs de température IoT that provide real time data and alerts when deviations occur. Chaîne de blocs et AI-driven analytics facilitate predictive maintenance and optimization of routes and cooling systems.
Packaged vs. Unpackaged Fish
Comme indiqué, unpackaged fish must be stored under ice, while packaged fresh fish may be kept slightly warmer. Packaging atmosphere matters: emballage sous atmosphère modifiée (CARTE) with reduced oxygen and increased CO₂ slows microbial growth, allowing storage at 3–5 °C without compromising safety. Vacuum sealed bags also extend shelf life by reducing oxidation.
Preventing Cross Contamination
Cross contamination can occur through contact with other foods, surfaces or water. Les principales précautions comprennent:
Separate storage – keep raw fish and shellfish away from cooked or ready to eat products.
Sanitize equipment and surfaces – clean cutting boards, knives and containers between uses. Use color coded tools to separate raw and cooked seafood.
Hygienic handling – employees should wear gloves, hair nets and protective clothing; wash hands frequently; and avoid touching face or other surfaces.
Regular audits and training – schedule internal audits to verify adherence to hygiene procedures and update training based on findings.
Documentation and Calibration
Maintenir calibrated thermometers and temperature logging devices est essentiel. Document calibration schedules, corrective actions and maintenance activities. Many operations integrate calibration reminders into digital management systems. En vertu de la FSMA, temperature monitoring records form part of the preventive controls plan; inaccurate or missing records can lead to citations.
Dealing with Short Term Temperature Deviations
Minor temperature excursions can occur during loading, unloading or equipment malfunction. Regulatory guidance allows short term deviations (Par exemple, 2–5 °C for fresh fish) if corrective action is taken quickly. Les meilleures pratiques incluent:
Rapid diagnosis and correction – identify the cause, adjust equipment or add ice, and document the incident.
Assess product impact – evaluate sensory quality and potential safety risks (Par exemple, histamine formation). Discard fish showing signs of spoilage.
Record the event – log the deviation, corrective actions and results to demonstrate due diligence during audits.
