Research-grade calculators for Salmonella dose-response risk, MicroTally® sampling efficacy, HPS virulence classification, and antimicrobial log-reduction validation — grounded in USDA-ARS MSQRU peer-reviewed science from Dr. Tommy L. Wheeler, Ph.D., Research Leader at USMARC, Clay Center, NE.
Live wholesale meat prices and carcass weight data by species. Auto-populates Carcass Type (SF12-S.004) with USDA average dressed weights for antimicrobial intervention modeling — Beef ~925 lb, Pork ~215 lb, Poultry ~6.3 lb.
Source: USDA AMS Livestock Mandatory Price Reporting. Reference data used as fallback.
USDA FSIS Salmonella Verification Testing Program — national baseline prevalence and concentration data by species and product category. Auto-populates SF12-S.001 concentration, SF12-S.002 prevalence %, SF12-S.003 log CFU/g by serotype, and SF12-S.004 initial carcass load.
Source: USDA FSIS Salmonella Verification Testing Program. Quarterly updated reference data (2023 annual report).
Compares FSIS NARMS baseline prevalence against MicroTally® and traditional detection probabilities from SF12-S.002. Shows the gap between what USDA reports is present vs what your current sampling program would actually detect.
Tip: A large gap between NARMS prevalence and your detection probability is the core ROI argument for MicroTally® adoption — use results in SF12-E.001.
Quantitative microbial risk assessment (QMRA) — estimates infection probability from Salmonella exposure in meat products using the Beta-Poisson dose-response model validated by USDA-ARS MSQRU research.
Compares pathogen detection probability between MicroTally® cloth-based samplers (commercialized by FREMONTA Corp) and traditional sponge/swab methods using binomial detection models — based on USDA-ARS MSQRU validation data.
Estimates probability of illness from Highly Pathogenic Salmonella (HPS) strains vs. non-HPS strains using serotype-specific severity weighting — based on the HPS Assay commercialized with Hygiena LLC from USDA-ARS MSQRU research.
Calculates expected log reduction of Salmonella from antimicrobial interventions at slaughter (lactic acid, peracetic acid, hot water, SCC) using USDA-FSIS validated performance parameters and USDA-ARS MSQRU decontamination research.
Built on USDA-ARS MSQRU research from Dr. Tommy L. Wheeler, Ph.D., Research Leader at USMARC, Clay Center, NE — including the science behind MicroTally® cloth-based sampling (commercialized by FREMONTA Corp), Salmonella PiLOT/CAT threshold testing, and the HPS Assay (commercialized by Hygiena LLC). These 4 scientific models translate federal meat safety research into quantitative risk assessments: from QMRA dose-response modeling to antimicrobial log-reduction validation. Part of AgrStak's 431-model platform — patent pending.
