A new investigation reveals that the fish sold on supermarket counters as fresh fish could be produced up to nine days before it is purchased by customers and that is has probably been frozen.

The study, by Premier Analytical Services and commissioned by Iceland Foods to look into the freshness of defrosted frozen fish versus fresh fish, tested four types of fish from four supermarkets: Iceland, Asda, Tesco and Sainsbury's, The Daily Mail reported.

The researchers claim that Iceland's frozen seabass, salmon and tuna is kept better in the fridge after being defrosted than fresh fillets from other supermarkets

The analysis found that frozen seabass and tuna lasted as long as fresh samples from Sainsbury's, and retained nutrients better than fresh fish from Tesco and Asda.

Sainsbury's, however, had the freshest tuna, seabass and trout, while Asda had the joint freshest salmon, along with Iceland.

The test revealed which samples of fish retained the most nutrients after 22 hours in the fridge.

A test on seabass found that Iceland's frozen fillet and Sainsbury's fresh fish counter sample both had mild odours and only slightly deteriorated after 22 hours.

But Asda's fresh fish counter seabass had 'significant' deterioration, while Tesco's fresh fish had a 'strong fish odour' that was 'pungent' and 'not fresh' after the same length of time.

It was the same for tuna, with both Iceland's frozen sample and Sainsbury's fresh fillet deteriorating the least after 22 hours.

On the other hand, the fresh Tesco and Asda fresh fish counter fillets meanwhile saw 'slight' deterioration.

When it came to the trout test, Sainsbury's fresh fillets kept the longest and retained their nutrients after a day in the fridge.

Iceland's Tesco's and Asda's samples had 'slight' deterioration meanwhile.

Salmon was the fish that retained most nutrients and kept for the longest overall, according to the study.

But fish counter fillets from Tesco and Sainsbury's showed 'slight' deterioration after a day, while a frozen sample from Iceland saw no significant change. Asda's fresh fish did not show any significant change either.

The test looked at the nutrient content of the fish samples before and after they had been kept in the fridge for 22 hours to note by how much the nutrients decreased by, if at all.

Neil Nugent, head development chef at Iceland said: 'We are keen to shine a light on the benefits of frozen fish - and highlight the nutritional benefits, quality and great variety available.

“Customers who buy straight out of a freezer will enjoy fish that's been preserved soon after it was caught for maximum freshness,” Nugent concluded.
