About Food Shelf Life Checker

A free, fast, privacy-friendly answer to one of the most common kitchen questions: “Is this still good?”

Food Shelf Life Checker started from a simple, recurring frustration. People constantly search for how long a specific food lasts — mushrooms in the fridge, cooked chicken in leftovers, an opened jar of sauce — and end up scrolling through ad-heavy single-food articles for one number. This site gathers that guidance into a single tool you can search in seconds, then adds something most articles skip: a date estimator that turns a storage window into an actual use-by date based on when you bought or cooked the food.

The tool runs entirely in your browser. Nothing you type is uploaded, tracked, or stored on a server, and you can use it offline once the page has loaded.

Where the data comes from

Storage windows are based on widely published, USDA FoodKeeper-style food-safety guidance and are kept deliberately conservative. They are general estimates for typical home conditions, not laboratory guarantees. Real shelf life depends on your refrigerator’s temperature, how fresh the food was when you bought it, and how it was packaged. The tool is meant to be used alongside your own senses, as explained in the guides on food storage and spotting spoilage.
