Food Safety Compliance Support
How Expert Guidance and Advanced Product Inspection Help Food Manufacturers Build Strong, Compliant Food Safety Programs
Food safety compliance involves more than just meeting regulatory requirements. It focuses on protecting consumers and your brand throughout the entire production process. At METTLER TOLEDO, we use advanced product inspection technology combined with decades of compliance experience to support food manufacturers in developing strong food safety management programs.
Our specialists assist you in identifying potential hazards, defining and verifying critical control points, and aligning inspection processes with GFSI-based standards and regulatory requirements. We support you from system selection through validation and ongoing performance checks, helping you develop a complete compliance framework that promotes both safety and productivity.
How can product inspection help my business comply with GFSI-recognized standards, food safety laws, and local regulations?
METTLER TOLEDO product inspection solutions help food manufacturers meet the globally recognized requirements of GFSI standards such as BRCGS, IFS, SQF, and FSSC 22000, as well as food safety regulations and laws like FSMA and the EU General Food Law. Our technologies support the implementation of HACCP-based food safety management systems that align with Codex Alimentarius principles.
Our advanced metal detection and x-ray inspection systems identify and remove physical contaminants such as metal, glass, and stone. Checkweighing and vision inspection systems verify fill levels, labels, and package integrity. These checks are essential for regulatory compliance and consumer protection.
In addition to quality inspection, we offer support for validation and verification processes, electronic documentation, and automated recordkeeping. These features simplify audits and demonstrate due diligence. Our inline systems deliver 100% inspection without compromising production efficiency, while ProdX software centralizes data collection and offers real-time monitoring to help keep operations audit-ready.

Documentation and Proof of Due Diligence
What documented evidence and records can product inspection systems generate to demonstrate due diligence during audits and investigations?
METTLER TOLEDO product inspection systems automatically generate secure, traceable records of every inspection, reject, and performance check. This helps food manufacturers simplify compliance documentation and audit preparation. Each record is time-stamped and stored as part of a tamperproof audit trail, supporting full traceability and accountability in food safety management systems.
With ProdX™ data management software, real-time production data, including batch and line details, is captured and organized for easy retrieval during food safety audits or regulatory investigations. This digital recordkeeping provides clear evidence of contamination control, fill accuracy, and label verification. It helps businesses demonstrate regulatory due diligence and compliance with standards such as BRCGS, IFS, SQF, and FSSC 22000.
By automating compliance data collection, manufacturers improve audit readiness, reduce manual paperwork, and maintain continuous visibility of inspection performance and product integrity.
Support of the Seven HACCP Principles
How can product inspection technology support the effective implementation of all seven HACCP principles in my food safety plan?
METTLER TOLEDO product inspection systems offer practical and measurable support at every stage of a HACCP-based food safety plan. By integrating inspection and verification directly into production lines, manufacturers can identify hazards early, monitor critical control points effectively, and maintain the records required to demonstrate compliance with GFSI-recognized standards and Codex Alimentarius HACCP principles.
1. Conducting a Hazard Analysis
The first HACCP principle focuses on identifying potential hazards that could affect product safety. METTLER TOLEDO specialists support food manufacturers early on by identifying where process risks and contamination hazards may occur. Our metal detection and x-ray inspection technologies play a key role in controlling physical contamination risks such as metal, glass, and stone.
2. Identifying Critical Control Points (CCPs)
We help manufacturers determine the most effective locations for CCPs within their process (such as raw material intake, in-process manufacturing steps, or end-of-line packaging) to manage contamination risks at critical stages.
3. Establishing Critical Limits
Our systems support the definition of critical limits with product-specific sensitivity settings and inspection parameters. These limits define the acceptable threshold for detection performance to maintain product safety and quality.
4. Monitoring CCPs
Routine monitoring and testing of inline systems performing 100% inspection at production speed helps confirm that devices are functioning as intended. ProdX data management software logs and tracks monitoring results, challenge tests, sensitivity checks, and validation processes.
5. Taking Corrective Actions
When deviations occur, inspection systems trigger alarms and generate event logs to allow for rapid intervention. This immediate response minimizes product waste, maintains control over affected batches, and lowers the risk of recall.
6. Verification Procedures
Regular performance verification is supported through annual assessments of the inspection device by trained technicians. This verification helps to confirm the device operates according to factory specifications and functions as intended.
7. Record-Keeping and Documentation
Secure, timestamped electronic records generated by inspection systems and recorded in ProdX create complete audit trails. These records can be quickly retrieved for internal reviews or external audits, simplifying compliance documentation and demonstrating due diligence.

CCP Identification and Line Positioning
Where should I place product inspection equipment on my production line to create effective Critical Control Points (CCPs) and reduce food safety risks?
Determining the optimal placement of product inspection equipment is essential to establish effective Critical Control Points (CCPs) and minimize food safety risks during production. METTLER TOLEDO helps manufacturers evaluate different placement options—from raw material intake and in-process stages to end-of-line inspection—to maximize risk reduction and operational efficiency.
The ALARA principle, known in radiation safety as the goal to reduce emissions "As Low As Reasonably Achievable," can also apply to contamination detection. In this context, it is referred to as the ALARM principle: "As Low As Reasonably Manageable." This principle guides manufacturers in defining detection limits and choosing CCP locations that reduce contamination risks to a manageable level. It balances food safety goals with technical feasibility, production speed, and cost.
By applying ALARM thinking, manufacturers can make informed decisions about where to position metal detectors and x-ray inspection systems to achieve effective hazard control. This approach creates a risk-based inspection strategy that helps prevent contaminated food products from reaching consumers while maintaining the practicality of daily operations.
How do product inspection systems support robust validation, ongoing verification and routine monitoring of my CCPs?
Product inspection technology plays a key role in confirming that Critical Control Points (CCPs) are effectively designed and operate reliably in daily production. METTLER TOLEDO supports manufacturers throughout this process, from initial validation to ongoing verification and routine monitoring. This helps manufacturers maintain consistent food safety and readiness for audits.
Validation activities confirm that inspection systems can detect specified contaminants under actual product, packaging, and production line conditions. This confirmation gives confidence that the selected critical limits are suitable and achievable for food safety. After validation, METTLER TOLEDO helps with ongoing verification by conducting annual visits and performance checks. These activities provide documented evidence that the inspection system maintains reliable detection capability over time.
Continuous 100% inline inspection combined with routine monitoring completes the process. Each product is inspected in real time; non-conforming packages are automatically rejected. Detailed inspection data, including monitoring activity results, are securely recorded with ProdX™ software for easy access and compliance reporting. This integrated process of validation, verification, and monitoring supports Codex based HACCP requirements. It also meets Global Food Safety Initiative (GFSI) and retailer standards, helping food manufacturers maintain safety assurance and operational efficiency.

Retailer Codes of Practice and Customer Expectations
How does product inspection help me meet retailer codes of practice and demonstrate that I am a reliable, compliant supplier?
Retailers and brand owners often have codes of practice that go beyond food safety laws and internationally recognized standards. These requirements can be highly detailed and prescriptive, setting expectations for contamination control, product integrity, labeling accuracy, and continuous monitoring. Failure to meet these rules can result in failed supplier audits, loss of preferred supplier status, or removal from approved supplier lists.
METTLER TOLEDO product inspection solutions help food manufacturers meet these retailer and customer expectations. Our systems detect and remove physical contaminants, verify correct labeling and packaging quality, and provide documented proof of inspection results to support retailer audits and supplier assessments.
Digital record-keeping and automated performance checks simplify demonstrating consistent compliance and due diligence over time. By combining proven technology with expert support, METTLER TOLEDO helps food producers build retailer trust, support supplier agreements, and maintain access to key markets.
