Can cooked shrimp that was frozen be refrozen again in the cooked food?!

Yes, its safe. I do it with casseroles and what not but the shrimp comes out much better if you defrost the dish in the refrigerated first and then reheat in the oven instead of microwave if possible. I even do it with seafood gumbo and reheat.

The answer to your question is yes.

However, here is some background on this .....

When you get home from the grocery store you can freeze “fresh” shrimp, but you can not re-freeze “previously frozen” uncooked shrimp. Shrimp, like all fish, should be cooked and eaten within 2 days of buying it. Unless you live on the seashore and buy from a local day fishermen practically all fish have been frozen onboard the fishing boats otherwise it would not keep as they go out for days at a time sometimes weeks.. So very little fish that arrives in your fish store counter/market is 'fresh' and has been previously frozen unless you are close to the sea.

Once something is cooked from fresh its state changes to another.

Generally, the deterioration of fresh fish is characterised by an initial loss of the fresh flavour, which is species-specific but may in general be described as "sweet" and "seaweedy". However, the compound trimethylamine (TMA) is an important component of the typical fishy smell of marine fish that has been stored for some time.

TMA is a product of bacterial metabolism of the compound trimethylamine oxide (TMAO), which occurs in appreciable amounts in marine fish as part of their osmoregulatory system. More specifically, TMAO may help to prevent the fish from becoming dehydrated in a salty environment. The microorganism that converts TMAO to TMA is usually a cold-tolerant Gram-negative bacterium. So, in short, if a fish smells fishy - it is an indication that it is going off.

Later in the spoilage process other components, such as the sulphurous notes from hydrogen sulphide, may add to the smell. As fish decay, the nitrogenous compounds in their bodies are converted into amines--organic (carbon-based) molecules containing nitrogen. As the process of decay continues, amines of lower and lower molecular mass are produced. Because compounds with lower molecular mass are generally more volatile than those of higher molecular mass, these smaller molecules are smellier. So, as time passes, the fish get more and more pungent.

Fresh fish does not smell because the amines they contain have a high enough molecular mass to prevent them from evaporating at room temperature.

No smell or very light smell is ok. I will not buy from any place that I can smell. If your local fish counter smells of fish it is dirty and the fish going off.

Buying frozen cooked shrimp with shells or pre-cleaned without shells (cooked meat usually pink to orange) saves a lot of messing about. Re-cooking it again within the other food it can be frozen for up to several months depending on the 'star' grade of your freezer. As correctly pointed out here, recooking food diminishes the taste in some foods especially fish/shellfish.

Fish/shrimp will not smell of anything if they are frozen immediately after being caught or have just been defrosted. I will never buy previously frozen fish/shrimp if they have been defrosted for more than 8 hours or have a hint of a fish smell.

Health wise, it is no problem. Once reheated the shrimp will probably overcook. If possible, I would freeze the cooked shrimp and the rest of the dish separately. When reheating your dish, add the shrimp back into your reheated dish at the end, just long enough to heat through.

Frozen food tastes less better than fresh food like shrimps. Because ice penetrates into the meat and less taste you get out of it. Then putting into frozen again will repeat this cycle. Your shrimp maybe better off in your fridge. Keeping it cold. And not go off.

I wouldn't. Refreezing food that was frozen and cooked not only reduces the flavor, but it might not be healthy.

Yes! Once it's cooked it's no problem.

Yes they can.

sure..but shrimp does get tougher with each cooking or reheating....
