My fish arrived partially thawed; can I refreeze it?

Although we ship our Wild Red fillets with dry ice, it is not uncommon for it to evaporate in transit. The key to the preservation of both the quality and nutritional value of the salmon is in the vacuum sealed pouch. This vacuum prevents the loss of nutrients and moisture from the salmon. In fact, provided that it is still cold to the touch, the salmon may be safely returned to a frozen state with no perceptible loss of quality.
