Common questions
How long do fresh clams, mussels and oysters last in the fridge?
5–10 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 fresh clams, mussels 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 fresh clams, mussels and oysters to keep them longer?
Freezing is not recommended for this food; the texture tends to suffer badly. Buy or cook only what you will use in time.
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.
