There are a few things to consider when determining how long seafood can sit out. The first is the type of seafood you are serving. Different types of seafood have different levels of spoilage and contamination. Seafood that is fresh, such as tuna, will have a longer shelf life than a fish that has been frozen and thawed multiple times.
The second thing to consider is whether or not the seafood was previously frozen. Freshly caught fish should always be eaten as soon as possible after being caught because they have a short lifespan before they begin to spoil. However, if seafood is going to be frozen before it reaches your plate, it can last much longer than fresh catch would allow.
For example, if you buy a bag of frozen shrimp at the store and leave it in your freezer for several weeks or months without cooking or eating it, it will still maintain its quality when thawed out and cooked properly. This is because freezing causes ice crystals to form inside the cells of the food product and these crystals kill harmful bacteria and parasites by rupturing cell walls and bursting them open so they cannot survive in our stomachs where they would cause illness or disease if consumed.
