Fish cold chain in the Azores: proving the service was delivered

Complaints put fish preservation under scrutiny

On 9 September 2026, PS/Azores published a parliamentary request by José Ávila concerning alleged failures in cold handling for fish air cargo travelling to and from Graciosa Island. According to the statement, exporters and importers say that the paid service may not always have been delivered regularly or adequately, including during transfers at Lajes Airport. These complaints still require investigation; they are not, by themselves, a technical finding about every shipment.

Without a history, a paid fee does not prove preservation

An invoice shows that a service was purchased, but it does not confirm the fish's actual temperature during waiting, transfer and flight. Operational evidence should answer basic questions: when did the cargo enter refrigerated storage, what temperature was measured, how long was it outside that environment, who held custody and what action followed a deviation? Without that sequence, it is difficult to distinguish a real failure, a delay, an isolated reading or a complaint without sufficient evidence.

A transfer is a change of custody

The greatest risk is not always in flight. It can arise at the dock, on the journey to the airport, while awaiting screening, during an intermediate transfer or at delivery. Every transition should have an accountable party, a time window and defined thermal limits. Real-time alerts allow intervention before quality becomes unrecoverable; a continuous history then supports a decision to release, inspect, downgrade or quarantine the lot.

The lot must carry evidence of its condition

The origin traceability promoted by FoodSteps (https://foodsteps.pt/) becomes more useful when it also follows condition throughout the journey. A Digital Product Passport can connect origin, species, lot, operator, temperature records, incidents, inspections and the final decision. Buyers and insurers then do not have to rely solely on conflicting accounts after delivery.

The goal is to prove service and accountability

The response to the Graciosa case should not stop at saying refrigeration is available. It should demonstrate, operation by operation, whether the purchased service was actually applied and whether agreed limits were met. That evidence protects producers, carriers, airport operators and buyers: it reduces disputes, accelerates claims and prevents fish without a reliable history from moving further into the food chain.
