How long does Fresh whole lobster last in the fridge?

The USDA rates 2 kinds of this separately
The USDA files 2 separate entries under this name — live and frozen — and they do not keep for the same time: Fresh whole lobster, live holds 1 day outside the freezer, Fresh whole lobster, frozen holds 1 day to 2 days.
The edge of its own category
Fresh whole lobster, live is the shortest-lived entry in the Seafood list: 1 day outside the freezer, against 2 days for Live clams, mussels, crab, and oysters, the item immediately above it. All 16 of the others keep longer. It stands 17 of 17 on its shelf, one step below Live clams, mussels, crab, and oysters at 2 days. Live and frozen are the same food in the source list.
Every storage figure the USDA publishes for this item
The USDA rates this item cold or frozen and never at room temperature: no pantry figure exists for it, as for 222 of the 466 foods in the data that get no pantry time at all. The source also indexes it as live and frozen.

What the USDA adds in words
The USDA attaches 1 handling note to this item, reproduced below word for word. It is about safety rather than quality, which is the distinction this data is easiest to get wrong. These are the source's own sentences, not ours, and they are the part of the FoodKeeper record that a table of durations cannot carry.
Fresh whole lobster, live, in the refrigerator, from the day you bought it. It is not safe to cook and eat a whole lobster if it is dead at the time of preparation.
Can you freeze fresh whole lobster?
Some kinds, yes. The USDA gives fresh whole lobster (frozen) 2–4 weeks in the freezer from the day you buy it; held at 0 °F food stays safe beyond that. For fresh whole lobster (live) it advises against freezing. Freeze it in moisture-proof wrap; fatty fish turns rancid sooner than lean fish, which is why its freezer time is shorter.
How to tell if fresh whole lobster has gone bad
Go by the date first: fresh whole lobster keeps 1 day in the fridge. A sour, ammonia-like or strongly fishy smell, milky slime, or flesh that no longer springs back means it goes out. Cook fish until it reaches 145 °F and flakes with a fork.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 1 day in the fridge. What decides that is the food and not the shelf the source files it on: Fresh whole lobster, live is an animal food, or made with one. Past it, it is not safe to eat: throw it out without tasting, because bacteria build up while food still looks and smells fine.
The figure in the freezer here is a quality window. The same page carries windows of more than one kind, so which sentence applies depends on which row you are reading, not on the food.
It is past the date. Now what?
Say the calculator above puts Fresh whole lobster, live past its 1 day in the fridge window, or the container sat out on the counter overnight. Throw the container out without tasting it, and count any hours it already spent out of the refrigerator as part of that window rather than on top of it.
The USDA's limit for perishable food standing at room temperature is 2 hours, or 1 hour when the kitchen is above 90 °F, and that clock runs whatever the storage figure says. Freezing stops the clock but does not turn it back: food already past its window is not rescued by putting it in the freezer. The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.

Where these numbers come from
Every storage time on this page is the USDA’s own published figure from the FoodKeeper data, one of the 9 it keeps per food, reproduced unchanged and never an estimate of ours. Where the USDA lists several kinds under one name, each kind keeps its own windows, and the page names the kind its answer is for. The dates and multipliers are ours, computed from those ranges.
