How long doesFresh whole lobsterlast 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.

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.

Turning the range into a date

Each kind gets its own dated rows here, 3 rows across the 2 the USDA lists under this name, because a date is only worth printing against the window it belongs to.

Is this window about safety or about taste?

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, throw it out rather than taste it: a perishable food can carry enough bacteria to make you ill while it 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. Held at 0 °F food stays safe for as long as it stays frozen, which is why a freezer figure counts as quality on this site whatever the food is. Every figure assumes the food was sound when you stored it, that your refrigerator holds 40 °F or below and your freezer 0 °F or below, and that the package was handled normally.

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 FoodKeeper entry this page is built from prints storage times and nothing else, so anything past them here is USDA and FSIS guidance rather than a figure from the source. The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.

Is that a long time?

Fresh whole lobster, live is the shortest-lived thing the USDA files under Seafood: 1 day, where the item above it, Live clams, mussels, crab, and oysters, holds 2 days and the middle of the 17-item list sits at 3 days.

Items that behave the same way

All 6 of the nearest items keep at least as long as Fresh whole lobster, live, 2 days to 4 days against its 1 day: it is the bottom of its own cluster.

Products the USDA rates in the same places

This is a common shape of record: 52 of the 466 products are rated in the same places, freezer from the day of purchase and refrigerator from the day of purchase, and 7 of the nine slots are left blank on all of them. Sorted by how close their windows are to this one, the nearest are Variety meats, Sausage and Stuffed, raw pork chops, and the rest of that group is what the list below draws on. Of the 8 shown, 8 keep longer than this one.

• Sausage1 day sealed in the fridgeraw bulk type or patties
• Stuffed, raw pork chops1 day sealed in the fridge

The rest of the Shellfish shelf

Every one of the other 10 products on the Shellfish shelf keeps longer outside the freezer than this one, from Shucked clams at 10 days down to Live clams at 2 days. The closest of them by window are Live clams, Scallops and Shrimp, crayfish, and the gap between this product and the rest of its shelf is the thing worth noticing here. Across the whole of Seafood the same product ranks 17 of 17. The middle of the shelf is Shrimp, crayfish, at 3 days.

If it has to keep longer than this

If it has to keep longer than 1 day, the Seafood aisle gives 16 products that hold at least twice as long outside the freezer. The smallest step up is Lean fish at 2 days against this one's 1 day; after it come Fatty fish, Live clams and Scallops. They are printed below in the order the step gets bigger, not alphabetically. The largest step the category offers is Herring at 6 months. Twice as long is the cutoff used here, so a product a few days apart from this one is not treated as a step.

The record this page is built from

The USDA publishes 2 separate rows under this name — records 158 and 161 — and this page carries all of them rather than picking one, because their windows differ. Between them they fill 2 of the nine storage slots with a time. Comparisons and the place in the category are computed for Fresh whole lobster, live, which is the kind the plain name means here, chosen kind by kind rather than by the order the source happens to list them in. 1 slot is marked not recommended, which is an answer rather than a gap.

Where these numbers come from

Every range on this page is published by the USDA FoodKeeper and reproduced unchanged. The multipliers, the rankings, the percentages and the dates are ours, computed from those ranges. Where the source gives a span such as 3 to 5 weeks, comparisons use the upper figure, and the full span is always printed.

Rankings cover only the items the USDA gives a usable figure for, and identical ranges share a place rather than being ordered arbitrarily. Neighbors are chosen by nearest storage time within the same category, never alphabetically: two foods filed next to each other by name usually have nothing to do with each other. The freezer is excluded from ranking because it flattens almost everything.

Where the USDA lists several kinds under one name, they share one page here and every kind keeps its own windows: the source prints them as separate rows, and a page that merged them would be inventing a figure the source never published. Comparisons and the place in the category are computed for the kind the plain name means — the shell egg for eggs, the can for tuna — which is settled name by name rather than by the order the source lists its rows in, and the page names it. Where the plain name means no single kind, the page prints no single figure at all and lists the kinds instead.
