Common questions
How long do hot dogs (opened) last in the fridge?
1 week once opened, and 2 weeks while sealed and unopened, in a fridge running at 0–5°C. Count from the day you open it, and use the printed date if it is earlier.
How can I tell if hot dogs (opened) have gone off?
A sour smell, a slimy or sticky surface or grey-green discolouration are all reasons to bin it. Do not rely on this alone: the time guideline matters even when everything looks fine.
Can I freeze hot dogs (opened) to keep them longer?
Yes. For best quality, freeze them for around 1–2 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.
