Common questions

How long do live clams, mussels, crab and oysters last in the fridge?

1–2 days in a fridge running at 0–5°C (USDA FoodKeeper guidance). After that, quality and safety both start to slip, and because the bacteria that cause food poisoning are invisible, ‘it seems fine’ is not a reliable test. When in doubt, throw it out.

How can I tell if live clams, mussels, crab and oysters have gone off?

A strong fishy or ammonia smell, a slimy surface, dull flesh or milky liquid in the pack are all reasons to bin it. Do not rely on this alone: the time guideline matters even when everything looks fine.

Can I freeze live clams, mussels, crab and oysters to keep them longer?

Yes. For best quality, freeze them for around 2–3 months; they stay safe beyond that because freezing halts bacterial growth, and only texture and flavour decline.

Does my fridge temperature really matter?

Yes. These times assume a fridge at 0–5°C, which is what the Food Standards Agency says to set it to. Bacteria grow faster in a warmer fridge, and many fridges run warmer than their dial suggests, so a cheap fridge thermometer is worth having.
