How long do Tortillas last in the fridge once opened?
Turning the range into a date
Tortillas (flour) keep 3 months in the fridge once opened. Each kind gets its own dated rows here, 5 rows across the 2 the USDA lists under this name, because a date is only worth printing against the window it belongs to.

The USDA rates 2 kinds of this separately
Tortillas, corn keeps 25 days, which is shorter than the window this page answers with. The USDA files 2 separate entries under this name — flour and corn — and gives every one of them the same window outside the freezer, 3 months. They are separate rows in the source rather than separate answers to the question.
The freezer helps less here than you would expect
The freezer buys less here than its reputation suggests: 2 times what the opened fridge gives, 3 months against 6 months, both still measured in months. For this item freezing is an extension rather than a different way of keeping it. On the same shelf it sits 19 of 23, between Teff at 4 months and Buckwheat at 2 months. Tortilla and corn are the same food in the source list.
Every storage figure the USDA publishes for this item
All three places the USDA recognizes are rated here — pantry, refrigerator and freezer — which only 65 of the 466 foods in the data manage. The source also indexes it as corn.

Can you freeze tortillas?
Yes. The USDA gives tortillas (flour) 6 months in the freezer from the day you buy them, and held at 0 °F food stays safe beyond that: the figure is about quality. Freeze it well wrapped while it is still well inside its fridge window: the freezer keeps quality, it does not restore it.
How to tell if tortillas have gone bad
Go by the date first: tortillas keep 3 months in the fridge once opened. A sour or off smell, mold, slime or an odd color mean it goes out. The bacteria that make people sick change none of these, so past its window it goes out even if it seems fine. Never taste to test.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 3 months in the fridge once opened. What decides that is the food and not the shelf the source files it on: Tortillas, flour is acid, dry, sweet, alcoholic or pure fat. Past it, whether it has gone bad is yours to judge by look and smell: this window rates quality, not the day it turns hazardous.
The figure in the fridge here is not settled by this record. 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.
It is past the date. Now what?
Say the calculator above puts Tortillas, flour past its 3 months in the fridge once opened window. Past that the calendar stops deciding and the food itself does. Insects or webbing in the package, a musty or rancid smell, or clumping that says damp got in mean it goes out whatever the date says.
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 whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.
Two places, and one of them is the wrong one
The USDA rates two places for Tortillas, corn in one state and they disagree: 60 days to 90 days in the fridge against 25 days to 45 days in the pantry. Of the two, the refrigerator is the longer. Both figures are the USDA's own, so this is a choice of where to put the food rather than a disagreement about how long it keeps.

Where these numbers come from
Every storage time on this page is the USDA’s own published figure from the FoodKeeper data, one of the 9 it keeps per food, reproduced unchanged and never an estimate of ours. Where the USDA lists several kinds under one name, each kind keeps its own windows, and the page names the kind its answer is for. The dates and multipliers are ours, computed from those ranges.
