In food processing, contamination control cannot rely on detection alone. By the time a foreign object is found, the issue has already happened. Stronger food safety starts earlier with better tool control, traceability, visual management, and hygienic zoning.

Sequential numbering, shadow boards, and colour coding help food manufacturers prevent foreign body contamination before it becomes a larger risk. Together, these simple systems improve accountability, reduce cross-contamination risk, and support a more controlled production environment.

In food manufacturing, colour isn’t a branding choice or a “nice-to-have.” It’s a food safety control measure - one of the simplest ways to reduce foreign body contamination risk before product ever reaches a metal detector or X-ray inspection step. The original article frames this perfectly: blue PPE and equipment increase contrast, strengthen visual checks, and reduce reliance on reactive detection systems.

This post explains why blue is the industry standard, where it makes the biggest difference, and how to use colour coding as part of a robust GMP and HACCP approach.

In food production, a knife isn’t just a tool. It’s a foreign body risk (broken tips, missing blades, lost parts) and a health & safety risk (lacerations, unsafe blade changes, sharps disposal failures).

That’s why robust knife control systems tend to look the same across well-run sites:
unique IDs, controlled issue/return, controlled blade changes, routine reconciliation, and a clear “missing knife/blade” response.

If you’re searching for a metal detector verification check log template (or an X-ray verification check sheet) you’re probably in one of two situations:

1. You’re tightening controls ahead of an audit, or
2. Something went wrong on the line and you don’t want a repeat.

Either way, the goal is the same: prove your detection step is working today, on this product, on this line, with records that hold up under scrutiny.

“Detectable” is one of the most misunderstood words in food safety. This post strips the jargon away and explains  how metal-detectable and X-ray-detectable polymers actually work, where each one helps, where they don’t, and how QA teams should specify and validate them without creating false confidence.

If you’re approving pens, scrapers, seals, gaskets, O-rings, cable ties, or PPE made from “detectable plastic”, this is the bit you want to get right.

Foreign body control usually fixates on the obvious culprits: pens, blades, hairnets, clipboards. Fair. They’re visible, portable, and easy to police.

But the nastier failures often come from the quiet stuff: seals, gaskets and O-rings - the engineering consumables that sit inside valves, pumps, fillers and connectors, get hammered by heat/chemicals/pressure, and then shed fragments when nobody’s looking.

Foreign body control usually fails in the most boring way possible: a small item goes missing, nobody knows when, and the evidence trail is vibes. BRCGS Issue 9 tightened expectations around portable handheld items in open product areas (Clause 4.9.6.2) - not just pens, but the wider universe of “stuff that can fall into product.”

Cable ties are the ultimate “tiny part, big consequence” item. They live inside panels, around guards, on conveyors, and in maintenance pockets—exactly where vibration, washdown, and human nature conspire to turn them into surprise foreign bodies. This guide is a practical playbook for food and pharma sites that want fewer near-misses, fewer line stops, and cleaner audit outcomes.

From our headquarters in Pocklington, Yorkshire, we supply metal detectable and X-ray visible products not only across the UK, but also to food and pharmaceutical manufacturers throughout Africa and the Middle East. Our job is simple: help you reduce foreign body contamination risks, strengthen your audits and protect your brand – wherever your lines are running.

Food-safety failures rarely happen because a standard was missing or a procedure didn’t exist. They happen because people didn’t follow the process consistently, often under pressure, fatigue, or time constraints. Regulations, certifications, and audits set the framework — but food-safety culture determines whether that framework holds up on a busy production floor. This article explores how training, digital audits, and small behavioural reinforcements work together to build a food-safety culture that’s resilient, audit-ready, and practical in real-world operations.
