How Long Do Hot Dogs Last?
Hot dogs last 1 week in the fridge after opening and 2 weeks unopened. They freeze well for 1–2 months. Cooked hot dogs keep 3–4 days, and none should sit out over 2 hours.
Hot Dogs — opened
shelf life- Unopened: 2 weeks in the fridge
- Cooked: 3–4 days in the fridge
Fridge at 40°F (4°C) or below · freezer at 0°F (−18°C). Freezer times are for best quality; frozen food stays safe longer.
Hot dogs are fully cooked, cured sausages of finely ground beef, pork or poultry, vacuum packed in a little brine. Being precooked and sealed gives them a long unopened life, but they are a known vehicle for Listeria, a bacterium that keeps growing at refrigerator temperatures, so the opened-package limit matters more than it seems.
How to store hot dogs
- After opening, move the remaining hot dogs and none of the package liquid into a zip-top bag or sealed container; the torn original pack dries them out and leaks.
- Wash your hands after handling the package juice and keep it off counters and other food; USDA flags the liquid as a possible source of Listeria.
- Freeze hot dogs in the unopened pack, or individually wrapped, so you can thaw two at a time. They can be boiled or grilled straight from frozen.
- For a cookout, keep the package in the cooler until grilling and do not put unused hot dogs that sat out for hours back in the fridge.
How to tell if hot dogs have gone bad
- A slimy, sticky coating on the franks that does not rinse away.
- Package liquid that has turned milky or cloudy instead of clear.
- A sour or tangy smell, or a swollen package.
- Color dulling to gray or brown, or dark, dry, wrinkled ends on hot dogs from an opened pack.
Bacteria that cause food poisoning usually do not change the look, smell or taste of food. Go by the time limits first, and the signs above second.

Not safe = perishable: no more than 2 hours at room temperature (1 hour above 90°F / 32°C). Not recommended = possible, but quality suffers or it serves no purpose.
Frequently asked questions
How long are hot dogs good after the package is opened?
Hot dogs are good for 1 week after opening, kept in a sealed bag or container at 40°F (4°C) or colder. That limit applies even if the printed date is a month away, since the date only covers the unbroken vacuum seal. Freeze any you will not eat within the week.
Can you eat hot dogs straight from the package without cooking them?
They are fully cooked, but USDA and CDC advise reheating hot dogs until steaming hot, 165°F (74°C), before eating. The concern is Listeria picked up after cooking at the plant. This is especially important for pregnant women, adults over 65 and anyone with a weakened immune system.
Are hot dogs safe to eat after the expiration date?
Unopened hot dogs should be eaten by their use-by date; with only a sell-by date, USDA allows up to 2 weeks of refrigerated storage at home. Past that, discard them even if they look fine, because Listeria grows in the cold without changing smell or appearance.
What is the white slime or cloudy liquid on my hot dogs?
Milky liquid and a slippery film are signs of bacterial growth, and the package should be thrown away. A small amount of clear brine in a fresh pack is normal, as are white flecks of solidified fat on franks that were chilled. If the film feels slick rather than greasy, do not rinse and eat them.
Can you refreeze hot dogs after thawing?
Yes, if they were thawed in the fridge and have been there less than a week. Texture suffers a little with each freeze, turning slightly spongy. Hot dogs that thawed on the counter or in a cooler that warmed above 40°F (4°C) for more than 2 hours should be discarded.
