Economic analysis of fresh fish transportation

The aim of the project Optimization of fresh fish transport is to improve the handling of fresh fish products in container transport and thereby increase their shelf life and the possibility of further transport by sea from Iceland. In work component 4, the development of fresh fish transport from Iceland is analyzed according to the mode of transport and the main market areas for fresh fillets and pieces. An economic analysis of the use of pots and foam boxes is carried out with regard to packaging and transport costs. Exports of fresh whitefish fillets and pieces have increased rapidly over the past decade. Year after year, the amount of fresh fillets and chunks imported from Iceland by sea increases. A product that was almost exclusively transported by air a decade ago is now almost equally transported by ship. The results show that the amount of fresh fillets and pieces transported by ship from Iceland almost increased sixfold from 2004 to 2014. In 2013 and 2014, about 90% of the fresh fillets and pieces transported by ship were transported to two markets; Britain and France. The results of a cost analysis show that it is considerably cheaper to pack a product in a pot than a foam box. Transport costs are also lower in most cases when comparing pots with foam boxes. It is more than half as low when comparing the cost of transporting a container of pots on the one hand and 3 kg of foam boxes on the other. However, there are some limiting factors in the use of pots. All things being equal, pots are not likely to replace a foam box except in part due to practical aspects of product distribution. In some cases, however, transport in pots could be very suitable.

The aim of the project Optimization of fresh fish transport is to improve handling of sea transported fresh fish products, thereby improving their quality and increasing the possibility of sea transport from Iceland. The aim of work package no. 4 is to analyze main markets and the development of fresh fish transport from Iceland. Also compare cost of traditional packaging in expanded polystyrene (EPS) boxes to pack the product in tubs containing slurry ice. Export of fresh white fish fillets and loins from Iceland has increased rapidly over the last decade. More and more fillets and loins are transported with ships. What used to be an exclusive air freight business is now almost equal (air vs. sea). The results show that the volume of fillets and loins transported with ships from Iceland nearly six folded from 2004 to 2014. In 2013 and 2014 almost 90% of the export went to two markets; Britain and France. Results show that cost of packing product in tubs is significantly lower than using EPS boxes. Transportation cost was also lower in most cases when using tubs than EPS, as much as half of the cost when compared to the smallest EPS box (3 kg) in a full container. Some factors limit the practicality of using tubs rather than EPS. It is unlikely that tubs will replace boxes unless introducing matching distribution options. In some cases using tubs can be both practical and very cost efficient.

Functionality testing of selected Chill ‐ on technologies during a transport ‐ simulation study of palletized cod boxes: qPCR for fish spoilage bacteria, SLP model and QMRA to evaluate pathogen growth in spiked cod

In this study, tests were carried out on technical solutions developed in the EU project Chill ‐ on, where a simulation experiment was set up to simulate the actual transport of fish from Iceland to Europe. The temperature fluctuations experienced by the fish were aimed at mimicking transport from Iceland to France by ship. Pallets of cod fillets in foam plastic boxes were transported to the Westman Islands by ship and back to Matís in Reykjavík. Samples from these pallets were then compared with control samples that had been stored in Matís' refrigerated conditions. Cod nuggets were also packed in consumer packs (trays) immediately after processing and then after 6 days and were stored in subcooled or refrigerated conditions. Microbial growth experiments were also performed in which Listeria monocytogenes, Escherichia coli and Salmonella Dublin were added to cod necks stored in foam boxes in conditions similar to the storage and transport processes during export. Temperature measurements, sensory evaluation, microbial and chemical measurements were used to present data to test and verify the QMRA / SLP models and quantification of Pseudomonas bacteria using qPCR technology.

The aim of the cod wet trials and the corresponding shelf life study was to include scenarios to test and demonstrate the functionality of some Chill ‐ on technologies in a simulated cod supply chain. Temperature fluctuations were induced according to the actual scenario in the supply chain of cod from Iceland to France via sea freight. The study included sample groups created at the point of processing after packaging in EPS boxes. The reference group was stored at Matís under superchilled conditions. Simulation trials for downward distribution were performed at Matís upon receipt of the pallets shipped to the Westman Isles from Reykjavik (Iceland ‐ Europe freight simulation) and compared with the reference group. Repackaging of loins in retail trays was performed on days 0 and 6 with storage under superchilled and chilled conditions, respectively. In addition, a pathogen challenge trial was performed by spiking loins (5 kg) with Listeria monocytogenes, Escherichia coli and Salmonella Dublin, followed by storage in EPS boxes under temperature conditions simulating export and distribution. Temperature recordings along with microbial, chemical and sensory analyzes from the groups evaluated provided necessary data to test and validate the QMRA / SLP models and the quantitative molecular (qPCR) method to estimate counts of pseudomonads.
