Quantitative assessment of the effectiveness of intervention steps to reduce the risk of contamination of ready-to-eat baby spinach with Salmonella

► Quantitative risk assessment of interventions at a baby spinach packinghouse was conducted. ► The tool allows producers to evaluate scenarios for risk of contamination with Salmonella. ► Results demonstrate that common packinghouse practices are not sufficient to avoid risk of an outbreak. ► Cross-contamination is the most probable scenario for prevalence of contamination on an entire lot of daily production.
