How long doDipslast in the fridge?
Why the freezer is not an option here
The USDA marks the freezer as not recommended for this item, so the whole answer is a single field: 2 weeks in the refrigerator from the day of purchase. It is not a warning: food held at 0 °F stays safe, so a not-recommended is a verdict on what would come out of the freezer.
Every storage figure the USDA publishes for this item
The refrigerator is the only place the USDA gives this item a storage time, as it does for 64 of the 466 foods the USDA lists.

Turning the range into a date
One row, one deadline: 2 weeks in the refrigerator from the day of purchase, counted from the day it went in rather than the day it was made.

Is this window about safety or about taste?
The answer at the top of this page reads 2 weeks in the fridge. What decides that is the food and not the shelf the source files it on: Dips, sour cream based is an animal food, or made with one. 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.
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 Dips, sour cream based past its 2 weeks in the fridge 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. 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?
8 items in the Dairy Products & Eggs list keep exactly as long as this item, 2 weeks, so they all share place 12 of 29 rather than being put in an order the data does not support. Among the 340 foods the USDA also gives a refrigerator figure, it keeps longer than 53% of them.
Items that behave the same way
All 4 of the 6 items nearest this item keep exactly as long as it does, 2 weeks, so the ranking around it is a tie rather than an order.
Products the USDA rates in the same places
14 other products are rated in exactly these places — refrigerator from the day of purchase — out of the 466 in the file, so this is an uncommon shape of record. The nearest of them by keeping time are Cream cheese, Commercial brand vacuum-packed dinners and Lettuce. 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. The longest-keeping of them is Cream cheese at 2 weeks.

The rest of the Dairy Products & Eggs shelf
The USDA puts this product on the Dairy Products & Eggs shelf together with 28 others, and 11 of them keep longer outside the freezer. The shelf runs from Powdered milk at 5 years down to Pudding at 2 days. Nearest this product by window are Buttermilk, Cottage cheese and Cream cheese, which is the order the list below is printed in. Across the whole of Dairy Products & Eggs the same product ranks 12 of 29. The middle of the shelf is Whipped topping, at 2 weeks.

If it has to keep longer than this
If it has to keep longer than 2 weeks, the Dairy Products & Eggs aisle gives 10 products that hold at least twice as long outside the freezer. The smallest step up is Whipped cream at 4 weeks against this one's 2 weeks; after it come Pimento cheese, Eggs and Butter. They are printed below in the order the step gets bigger, not alphabetically. In the other direction, 5 entries in the category keep half as long or less, Kefir and Eggnog among them. The largest step the category offers is Powdered milk at 5 years.

The record this page is built from
This page is built from a single FoodKeeper row, record 16 — the source’s own number for it, not a position — one of the 661 rows in the snapshot. That row fills 1 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. 1 slot is marked not recommended, which is an answer rather than a gap.
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.
