Initial Contamination. PG - 100036 LID - S0362-028X(22)10150-X [pii] LID - 10.1016/j.jfp.2022.100036 [doi] AB - The Poultry Food Assess Risk Model (PFARM) project was initiated in 1995 to develop data collection and modeling methods for simulating the risk of salmonellosis from poultry food produced by individual production chains. In the present study, the Initial Contamination (IC) step of PFARM for Salmonella and chicken gizzards (CG) was conducted as a case study. Salmonella prevalence (Pr), number (N), and serotype/zoonotic potential (ZP) data (n = 100) for one sample size (56 g) of CG were collected at meal preparation (MP), and then Monte Carlo simulation (MCS) was used to obtain data for other sample sizes (112, 168, 224, 280 g). The PFARM was developed in Excel and was simulated with @Risk. Data were simulated using a moving window of 60 samples to determine how Salmonella Pr, N, and ZP changed over time in the production chain. The ability of Salmonella to survive, grow, and spread in the production chain and food, and then cause disease in humans was ZP, which was based on U. S. Centers for Disease Control and Prevention data for salmonellosis. Of 100 CG samples tested, 35 were contaminated with Salmonella with N from 0 to 0.809 (median) to 2.788 log per 56 g. Salmonella serotype Pr per 56 g was 16% for Kentucky (ZP(mode) = 1.1), 9% for Infantis (ZP(mode) = 4.4), 6% for Enteritidis (ZP(mode) = 5.0), 3% for Typhimurium (ZP(mode) = 4.9), and 1% for Thompson (ZP(mode) = 3.7). Results from MCS indicated that Salmonella Pr, N, and ZP among portions of CG at MP changed (P
