Foreign Body Materials: Management Principles and Root Cause Investigations

On Demand Until August 24, 2022

Duration:60 minutes

While zero defects is the ultimate goal, nearly every food business will experience a foreign body incident at some point. Most businesses focus on microbiological hazards as they are the most well-known food safety risk, but foreign bodies also pose a risk and should not be ignored.

A good food defense program is key to preventing foreign body intrusions, but once an object is discovered, what happens next?

This webinar discusses foreign body principles and introduces two fast and effective tools, FTIR and XRF, which are used to assist in the root-cause investigation and identification.

Key learning objectives:
  • Food safety impact of foreign bodies
  • Foreign body principles: build awareness, promote best practices and develop prevention plans
  • Analytical tools with a focus on XRF and FTIR to assist in root cause investigations
  • Real factory-level case study examples
