Meat & Poultry Lethality Calculator
Calculate cooking time and temperature combinations for meat and poultry using data from the USDA FSIS Revised Appendix A. The calculator returns an answer only when an exact row exists in the 2021 tables. It does not interpolate, estimate, or invent values.

Exact source match · FSIS-GD-2021-0014 · December 2021
This calculator is based on data published in the USDA FSIS Cooking Guideline for Meat and Poultry Products (Revised Appendix A, 2021). It is an informational tool and is not an official FSIS calculator or regulatory determination.
How it works
Options in the form are loaded from verified rows in the database. The backend looks up the active 2021 source version with a deterministic query. If the combination is not an exact table row, the response is no exact match plus the nearest published temperatures. There is no AI in the numerical path.
