Temperature history from three air and three sea freights of fresh cod loins and haddock fillets ... more Temperature history from three air and three sea freights of fresh cod loins and haddock fillets in expanded polystyrene boxes from Iceland to the U.K. and France were analyzed to find out the effect of different factors on the temperature profile and predicted remaining shelf life (RSL) of the product. It was also aimed to pinpoint hazardous steps in the supply chains. Significant difference (P < 0.001) was found in: the temperature at different locations inside a certain box; mean product temperature between boxes of a certain shipment; and the boxes' surface temperature at different positions on a pallet for the whole logistics period. The predicted RSL depends on the time and temperature history of the product, shortest for sea transportation and longest for an air shipment with precooled product. Several critical steps were found in air freighting: the flight itself, loading/unloading operations and holding storage at unchilled conditions.

The work aimed at testing the possibility of extending the application of the TTI kinetic model, developed for specific temperature range of isothermal conditions, at low temperatures. The results showed that the TTI presented reproducible responses after being charged and during the discolouration process under different conditions, which revealed the reliability of the indicator. The TTI reflected well the temperature conditions of the studied scenarios, which indicates its potential application to continuously monitor the temperature history of the fresh fish supply chain. The kinetic model gave good fits in non-abused scenarios at temperatures below 2°C, presenting the potential for application of the model in determining the right charging level to suit a product's shelf life at low temperatures.

TTI placed on the bottom of the packs effectively reflected the temperature condition of the product. TTI with the initial square value of 61 was suitable for continuous monitoring of the quality and shelf life of the product repacked on day 6 after processing. The estimated product shelf lives based on TTI and on the square-root model for relative rate of spoilage of fresh seafood were well correlated.

Furthermore, ex ante cost-benefit analyses (CBAs) of adopting new traceability systems are conducted for two firms, operating at different steps of the seafood supply chains, to obtain preliminary knowledge on the net benefits of the project and on how costs and benefits are distributed among the actors. Design/methodology/approach -This is a case-based study. Findings -The surveyed companies perceive improving supply chain management as the most important benefit of traceability. Other benefits are increase of the ability to retain existing customers; product quality improvement; product differentiation; and reduction of customer complaints. However, the quantifiable benefits are perceived differently by the actors at different steps in the supply chains, e.g. implementing radio frequency identification (RFID) tags on pallets in the seafood trading company case study shows tangibly quantifiable benefits. Originality/value -The paper is useful for both practitioners and academics regarding perceived benefits of traceability in fish supply chains. The research provides initial insight into seafood companies' perspectives on the benefits of adopting RFID-based traceability solutions. The paper suggests that the financial burden of implementing traceability may be borne by the processing firms, while gains are reaped by firms in the distribution business closer to the end consumer. This could provide a partial explanation as to why traceability has been slow to gain ground as a visible value-adding marketing tool, and is mainly being driven by food safety regulations.

The framework was based on a broad literature review from the food processing industry. The proposed framework was then applied to evaluate the traceability system at a Vietnamese fresh farmed Pangasius catfish producer and validated by evaluating the ability to track and trace through the company. In addition, the studied traceability system was analyzed on its compliance with regulation on traceability of importing countries such as EU regulation No. 178/2002, as well as with the TraceFish standard. The paper also aimed to propose how to use recorded data more efficiently to improve quality management and supply chain management. The results show that the framework works well in the specified case, but further investigation for other cases is desirable. The company traceability system meets with EU regulation No. 178/2002, but not with the TraceFish standard as global trade item numbers (GTIN) are not used for dispatched products. It is suggested that the company also stores recorded data in electronic form in parallel with paper form to facilitate data access. It is proposed that the temperature data during storage and transportation are used to estimate the warm up time and the remaining shelf life (RSL) of the products.
