Know what the reference can tell you
FoodSafety.gov describes FoodKeeper as a storage reference developed by USDA FSIS with Cornell University and the Food Marketing Institute. It covers food and beverages and is intended to support freshness and quality through proper storage.
It is available on the web and as a mobile app. Its entries describe general product categories. The reference cannot scan your package, monitor the refrigerator, know when a seal was opened, or identify a recall automatically.
Search for the food in its current state
Distinguish dry rice from cooked rice, raw poultry from cooked leftovers, and unopened packages from opened ones. Similar names can lead to different storage locations and ranges.
Read the whole entry, including pantry, refrigerator, freezer, after-opening, or after-preparation context. Keep manufacturer directions when they are more specific to the exact product.
Add the handling history FoodKeeper cannot see
Confirm that refrigerated food stayed at 40°F (4°C) or below and frozen food at 0°F (-18°C) or below. Account for room-temperature exposure, power interruptions, leaking packages, and cross-contamination.
A matching entry does not resolve uncertain temperature history. Use outage guidance, recall notices, or professional advice when the event calls for it.
Save enough context to check again later
Transfer the product name, storage state, opened or prepared date, and source link into an inventory. The resulting reminder should prompt a review of the item and current guidance.
Recheck the source when making a later decision because web guidance and product instructions can change. Unless the reference makes that claim, do not describe a calculated date as guaranteed safe or expired.

Questions that need a little more context
Is FoodKeeper a safety detector?
No. It cannot observe temperature, contamination, package condition, or handling history.
Who developed it?
USDA FSIS, Cornell University, and the Food Marketing Institute, according to FoodSafety.gov.
Should its range replace the package label?
No. Keep and follow product-specific directions and use the reference for additional context.
Why save the source link with an inventory note?
A copied number loses product state, temperature assumptions, and update context. Saving the source makes it possible to recheck the exact entry when the household decision occurs later.
