FoodStorageCheck quotes one primary source and links two supporting ones. We do not mix in blog folklore, manufacturer marketing, or crowd-sourced guesses.
Primary: USDA FSIS FoodKeeper data
The FoodKeeper dataset is maintained by the U.S. Department of Agriculture’s Food Safety and Inspection Service with Cornell University and the Food Marketing Institute. It powers the federal FoodKeeper app. Our current snapshot:
| Dataset | FSIS FoodKeeper Data on catalog.data.gov (English JSON resource) |

- FoodSafety.gov FoodKeeper page — the official companion to the dataset.
Update process
A single command re-downloads the official file, records its size, checksum, and retrieval time in a machine-readable manifest, re-runs normalization and every validation rule, and regenerates a data-quality report. If any blocking error appears, the refresh is rejected and the previous snapshot stays live. The application never fetches from USDA at page-load time, so an upstream outage can’t change or break the answers you see.
Independence
FoodStorageCheck is an independent project. It is not affiliated with, operated by, or endorsed by USDA, FSIS, or FoodSafety.gov. We quote their public-domain data with attribution because it is the most rigorous storage reference available. See how we process it on the methodology page, or report a correction.
