Over the past year, there has been an increasing amount of recalls due to foreign objects. While these foreign objects may not result in any major injuries, the cost of conducting a recall warrants companies putting in more effort in foreign object control. This goes beyond just having a metal detector installed into the process.
First, many metal detectors do not get the attention they need. A really nice guide for metal detectors is "The Guide to Reducing Metal Contamination in the Food Processing Industry" published by Safeline.
X-ray equipment is much more affordable than it once was, and it can pick-up items metal detectors can't, such as glass, hard plastic, stones, etc. They are even suitable for metal and foil containers.
But detection is just one part of a foreign object control program. Other important elements include raw material inspection, preventive maintenance, employee training to prevent accidental drops, and controls at ingredient addition steps to prevent foreign material from packaging and inline preventive devices such as magnets and sifters.
All of these systems need to be properly maintained and verified for performance. Additionally, consumer complaints must be reviewed with an investigation and appropriate corrective action for any foreign material issues.
