Food safety: Why metal is still the biggest and most likely contaminant

by Fortress Technology, UK

Metal remains the biggest and most likely contaminant risk within food processing and packing plants today. But why is that? In the raw ingredient phase, food is exposed to different processes - from cutting meat, filleting fish, grinding spice or mixing dry and wet baking ingredients. Later down the line, you may be cutting larger quantities into more convenient single serve portions or preparing ready-cut vegetables - again introducing a possible metal contaminant into the food supply chain.

 


As industrial metal detector specialists, Fortress Technology answers some of the most common questions pitched to them by food factories:

How has the rapid uptake of automation impacted food safety on food processing lines?
Using equipment to improve efficiencies, and product costs in some situations, the need for sufficient checks and preventative maintenance practices becomes mandatory. Previously, a team of manual operators would visually inspect wear of machine parts and wire mesh from sieves for example, yet with fewer manual workers on a line, the risk of metal contaminants increases.

Installing a metal detection system is the first line of defense. However, it is equally important to use metal detection in conjunction with a quality assurance program, ensuring proper procedures are in place for controlling rejects, and as a fool-proof process to determine the source of any contaminants picked up. Equipped with this information, appropriate actions can be taken to protect against costly product recalls and damage to brand reputation.

How have retailer requirements changed and what’s the impact on food safety standards?
In recent years, retailers have become more risk-averse when it comes to food safety and quality, imposing their own – increasingly stringent – protocols and standards on suppliers. Food processors can feel overwhelmed by the sheer extent of choices, food safety initiatives and third-party audits that they must contend with.

Companies need to ensure that the required form of inspection and necessary specifications are in place. A retailer ‘safety net’ will also often include assurances about regular system checks to ensure that all QA systems – including metal detection – are functioning correctly.

Some retailers may put pressure on suppliers, or potential suppliers, to invest in x-ray contaminant detection. Being able to demonstrate the reliability and improved sensitivity of installed metal detectors (with FM software, for example) may be one way to resist this sort of pressure.
