Live lobster past the expiration date
Best-by and sell-by
FoodKeeper gives unopened live lobster 1 day in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Past the date
For perishable live lobster, the storage clock matters more than the label: if it has been in the fridge longer than 1 day, discard it even before the printed date.
How to keep live lobster fresh longer
- It is not safe to cook and eat a whole lobster if it is dead at the time of preparation.
- Keep on ice or in the coldest part of the fridge, at 40°F (4°C) or below.
- Store live shellfish in a bowl covered with a damp cloth, never in water or sealed plastic.
