⚖ Food Safety Gap
☣ USDA FSIS — Pathogen Thermal Inactivation Benchmarks

USDA FSIS validated D-values and z-values for key foodborne pathogens from published Appendix A/B performance standards and scientific literature. Auto-populates D-value, z-value, and reference temperature in the Thermal Death Time (TDT) calculator, and sets the target organism dropdown.

Select pathogen and food matrix to load USDA FSIS thermal inactivation benchmarks.

Source: USDA FSIS Appendix A (1999, updated). D/z-values from validated thermal processing literature. Always verify with current FSIS performance standards for your specific product.

🍙 USDA FoodData Central — Nutrient Reference Values

USDA FoodData Central typical nutrient composition for common food categories. Auto-populates fat, saturated fat, carbohydrates, fiber, sugars, protein, and sodium in the Nutrition Label Generator (per 100g basis, adjustable by serving size).

Select food category and serving size to load USDA FoodData Central nutrient values.

Source: USDA FoodData Central. SR Legacy and Foundation Foods data. Values are per 100g unless adjusted by serving size. Live API attempted; reference data used as fallback.

⚖ Food Safety Gap Analysis

Compares your product's pH and water activity against USDA/FDA HACCP critical control limits to identify pathogen growth risk zones. Load FSIS data first for pathogen-specific context.

Load FSIS pathogen data first, then enter your product pH and water activity in the pH/aw calculator and click Build Safety Gap.

Tip: Cross-reference the gap output with your HACCP plan. Products in the "caution" zone for pH (4.0–4.6) or aw (0.85–0.92) may require additional critical control points.

๐Ÿฆ  Thermal Death Time Calculator

Model SF3-S.001

Calculate microbial lethality using D-values and z-values. Determine required processing time for target log reduction at a given temperature.

Time at reference temp to reduce population by 1 log (90%)
Temperature change for 1-log change in D-value
USDA requires 7-log for Salmonella in poultry, 5-log in ground beef

๐Ÿ“… Shelf Life Prediction

Model SF3-S.002

Predict product shelf life at different storage temperatures using the Arrhenius model. Estimate Q10 acceleration factor for accelerated shelf life testing.

Rate increase per 10ยฐC rise. Typical: 1.5-4 for food degradation
For ASLT: test at elevated temp to predict normal shelf life

๐Ÿ’ง Water Activity (aw) Calculator

Model SF3-S.003

Estimate water activity from moisture content and composition. Assess microbial safety limits and predict product stability.

๐Ÿท๏ธ Nutritional Label Calculator

Model SF3-S.004

Calculate Nutrition Facts values per serving. Computes calories, % Daily Values, and FDA-compliant rounding rules for food labeling.

โš—๏ธ pH & Acidity Safety Assessment

Model SF3-S.005

Assess food safety based on pH and water activity classification. Determine if a product is acid/acidified food and applicable FDA regulations.

Optional โ€” expressed as % of primary acid
