Research Project: Produce Safety Research Collaboration with New Leaf Food Safety Solutions

Location: Environmental Microbial and Food Safety Laboratory

2012 Annual Report

1a.Objectives (from AD-416):
The objective of this cooperative research project is to facilitate the adoption of food safety interventions through pilot plant scaled experimental trials.

1b.Approach (from AD-416):
Non-pathogenic E. coli will be inoculated on fresh produce. The product will be washed in the pilot plant scaled wash system, subjecting to various sanitizers and wash technologies. The E. coli cells will be recovered from produce and wash water and quantified using standard plating or enrichment procedures.

3.Progress Report:

A pH controller has been donated by New Leaf Food Safety Solutions Inc. to the ARS. The equipment is now installed and operational at ARS facility. Two lines allow side-by-side comparison of T128 and citric acid for adjustment of pH in chlorinated wash water in our pilot plant produce washer. USDA-ARS scientist also traveled to New Leaf Food Safety Solutions facility to conduct pilot plant tests for preliminary assessment of the wash sequence on pathogen reduction.
