Refreezing food will result in a reduction of quality.
Due to health risks, no meat (or fish) should be refrozen after it has been thawed.
I assume you mean thawed - unthawed is refrozen! As long as that was the only time they have been frozen, they will be perfectly good. Most shell food and fish is perfectly good after being frozen, but beware, many supermarket fish/shellfish, have been frozen before being defrosted and put on display. Check the label to be sure.
Fish will weigh less after it is thawed because it loses some water when it is thawed.
No, frozen is frozen. But you can refreeze something that has been thawed. You can refreeze thawed meat long as there are still ice crystals on it. Once completely thawed then you need to cook it first then refreeze. This applies to solid pieces only, ground meat once more than half thawed needs to be cooked first then refrozen always.
According to the United States Department of Agriculture, frozen fish fillets that have been thawed under refrigeration and have been defrosted for no more than 2 days, can be safely refrozen. The safety may be fine, but the quality will likely be affected. If the fish was thawed using a different method, then refreezing is not an option. Other sites suggest the fish not be refrozen unless it is cooked.
Consuming fish that has been thawed in the fridge for 5 days can be risky as it may have started to spoil. It is generally recommended to consume fish within 1-2 days of thawing to ensure safety and freshness.
yes
Sure. Partially thaw the fish and then brine it - usually with a mixture of salt and sugar. It should smoke with no problems, and then can either be refrozen or canned.
My freezer was unplugged by a construction worker. I did not catch it for 2 days the food was cold but had defrosted. The fish was in sealed packages but pretty defrosted. Is it ok to refreeze it now or is it dangerous to eat?
