How to tell if cooked lobster tails are bad

Smell

Sour, yeasty or 'off' instead of how it smelled when cooked.

Texture

Slimy film, or liquid separating where it should not.

Colour

Dull or darkened patches, or any discoloured spots.

Mould

Any fuzzy growth — discard the whole container, not just the spot.

Cooked lobster tails past the expiration date

Best-by and sell-by

FoodKeeper gives unopened cooked lobster tails 2–3 days 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 cooked lobster tails, the storage clock matters more than the label: if it has been in the fridge longer than 2–3 days, discard it even before the printed date.

How to keep cooked lobster tails fresh longer

  • Refrigerate within 2 hours of cooking (1 hour above 90°F) in shallow, airtight containers.
  • Keep the fridge at or below 40°F (4°C); the door shelf is the warmest spot.
  • Reheat leftovers to 165°F (74°C) and only reheat what you will eat.
