How long doHot dogslast in the fridge once opened?

Freezing changes the unit, not just the number

Freezing does not just add time to this item, it changes the unit the answer is written in: 2 weeks in the sealed fridge against 2 months in the freezer, 4.3 times longer, months in place of weeks.

Every storage figure the USDA publishes for this item

The USDA rates this item cold or frozen and never at room temperature: no pantry figure exists for it, as for 222 of the 466 foods in the data that get no pantry time at all. Within Meat it is filed under Smoked or Processed.

• In the freezer1 month to 2 months
• Unopened · in the fridge2 weeks
• Once opened · in the fridge1 week

Turning the range into a date

Two clocks run on this item: one from the day it went into storage and one from the day the seal broke. Both are listed below, 3 rows in all.

Is this window about safety or about taste?

The answer at the top of this page reads 1 week in the fridge once opened. What decides that is the food: the source files Hot dogs under Meat, a heading it keeps for perishable food. Past it, throw it out rather than taste it: a perishable food can carry enough bacteria to make you ill while it still looks and smells fine.

The figure in the freezer here is a quality window. The same page carries windows of more than one kind, so which sentence applies depends on which row you are reading, not on the food. Held at 0 °F food stays safe for as long as it stays frozen, which is why a freezer figure counts as quality on this site whatever the food is. Every figure assumes the food was sound when you stored it, that your refrigerator holds 40 °F or below and your freezer 0 °F or below, and that the package was handled normally.

It is past the date. Now what?

Say the calculator above puts Hot dogs past its 1 week in the fridge once opened window, or the container sat out on the counter overnight. Throw the container out without tasting it, and count any hours it already spent out of the refrigerator as part of that window rather than on top of it.

The USDA's limit for perishable food standing at room temperature is 2 hours, or 1 hour when the kitchen is above 90 °F, and that clock runs whatever the storage figure says. Freezing stops the clock but does not turn it back: food already past its window is not rescued by putting it in the freezer. The FoodKeeper entry this page is built from prints storage times and nothing else, so anything past them here is USDA and FSIS guidance rather than a figure from the source. The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.

Is that a long time?

Among the 17 items the USDA files under Meat, this item ranks 5 by how long it keeps outside the freezer. Pastrami holds 40 days, Pork roll holds 7 days. Among the 340 foods the USDA also gives a refrigerator figure, it keeps longer than 53% of them.

Items that behave the same way

Every one of the 6 nearest items keeps the same or less, 3 days to 7 days against the 2 weeks of this item, which makes it the durable end of the cluster.

• Pork rollkeeps 7 days in the fridge once opened
• Baconkeeps 1 week in the fridge once opened
• Corned beef, in pouch with pickling juiceskeeps 5 days sealed in the fridge
• Venison, round, rump, loin, or rib roastkeeps 3 days sealed in the fridge
• Retort pouches or boxeskeeps 3 days in the fridge once opened
• Bratwurstkeeps 2 days in the fridgefresh

Products the USDA rates in the same places

5 other products are rated in exactly these places — freezer from the day of purchase, refrigerator from the day of purchase and refrigerator after opening — out of the 466 in the file, so this is an uncommon shape of record. The nearest of them by keeping time are Turkey bacon, Salami and Chicken. They are listed below with their own answers, closest first, which is why this list differs from the one on their pages. Of the ones shown, none keeps longer than this one does.

• Turkey bacon7 days in the fridge once openedup to 2 weeks sealed in the fridge
• Salami3 days in the fridge once openedup to 2 weeks sealed in the fridge
• Chicken1 day sealed in the fridgewhole
• Turkey1 day sealed in the fridgewhole
• Cheese5 kinds1 week to 12 months

Closest by shape, but not an exact match — they share most of these places, not all of them.

• Corned beef5 days sealed in the fridge
• Venison3 days sealed in the fridge

The rest of the Smoked or Processed shelf

The USDA puts this product on the Smoked or Processed shelf together with 6 others, and 2 of them keep longer outside the freezer. The shelf runs from Prosciutto at 3 months down to Sausage at 2 days. Nearest this product by window are Bacon, Corned beef and Pork roll, which is the order the list below is printed in. Across the whole of Meat the same product ranks 5 of 17. The middle of the shelf is Corned beef, at 7 days. The shelf is the source's own subcategory, Smoked or Processed inside Meat.

If it has to keep longer than this

If it has to keep longer than 2 weeks, Meat offers 4 products that hold at least twice as long outside the freezer. The nearest step up is Pastrami at 40 days against this one's 2 weeks, and the rest are Prosciutto, Jerky and Meat products. A short list like this one is itself the finding: the category has few longer options. In the other direction, 12 entries in the category keep half as long or less, Bacon and Corned beef among them. The largest step the category offers is Meat products at 5 years.

The record this page is built from

This page is built from a single FoodKeeper row, record 98 — the source’s own number for it, not a position — one of the 661 rows in the snapshot. That row fills 3 of the nine storage slots with a time, and the binding figure on it is printed by the source in weeks, which is the unit this page keeps rather than converting it to days. It is filed under Smoked or Processed inside Meat, which is where every shelf comparison on this page comes from.

Where these numbers come from

Every range on this page is published by the USDA FoodKeeper and reproduced unchanged. The multipliers, the rankings, the percentages and the dates are ours, computed from those ranges. Where the source gives a span such as 3 to 5 weeks, comparisons use the upper figure, and the full span is always printed.

Rankings cover only the items the USDA gives a usable figure for, and identical ranges share a place rather than being ordered arbitrarily. Neighbors are chosen by nearest storage time within the same category, never alphabetically: two foods filed next to each other by name usually have nothing to do with each other. The freezer is excluded from ranking because it flattens almost everything.

Where the USDA lists several kinds under one name, they share one page here and every kind keeps its own windows: the source prints them as separate rows, and a page that merged them would be inventing a figure the source never published. Comparisons and the place in the category are computed for the kind the plain name means — the shell egg for eggs, the can for tuna — which is settled name by name rather than by the order the source lists its rows in, and the page names it. Where the plain name means no single kind, the page prints no single figure at all and lists the kinds instead.
