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

Location: Environmental Microbial and Food Safety Laboratory

2013 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 donated by New Leaf Food Safety Solutions Inc. has been installed at the ARS fresh-cut pilot plant. The equipment is now fully operational and allows side-by-side comparison of T128 and citric acid for adjustment of pH in chlorinated wash water during fresh-cut produce processing. The equipment was further used during the testing of a novel feed-forward control of chlorine dosing program.
