UK – Thermo Fisher Scientific, an American biotechnology product development company has unveiled its latest metal detection technology which has met stringent standards set by UK leading retailer Marks & Spencer.

The “gold standard” requirements set by Marks & Spencer command some of the toughest food safety codes of practice for foreign object detection.

The technology will help food manufacturers supplying packaged products to retailers to -meet rigorous standards and Codes of Practice set by food retailers worldwide.

The Thermo Scientific Sentinel Multiscan Metal Detector can rapidly scan up to five frequencies at a time with an updated software and hardware features to meet the stringent standards.

Sentinel is a high-performance contaminant detection solution ideally suited to applications with high product effect, such as meat, dairy, bakery, confectionary and fresh fruits and vegetables. 

“Inspecting with the Sentinel Multiscan Metal Detector enables food manufacturers to demonstrate to retailers that their foreign object detection technology will help to avoid brand-damaging and costly recalls,” said Bob Ries, lead product manager, metal detection and X-ray inspection, Thermo Fisher Scientific. 

“As the trend towards adopting codes of practice grows, we are supporting the highest level of market need for compliant foreign object detection solutions across our portfolio of inspection and detection technologies.”

The codes of practice typically specify which type of foreign object detection system should be used, how it must function to ensure rejected products are removed from production and how the systems should “fail” safely under all conditions.

The codes also dictate how results should be audited, which records must be kept and the desired sensitivity for various metal detector apertures sizes.

Thermo Fisher noted that it has updated some of its technology including APEX Metal Detectors and NextGuard X-ray inspection systems with new features to ensure compliance with the retailer codes.

According to the company, this provides more options for food manufacturers based upon their manufacturing specifications and application.

Thermo Fisher, which is one of the leading companies in the genetic testing and precision laboratory equipment markets recently acquired Slovakia based mass spectrometry software provider HighChem.
