Take a moment and imagine a world where every single food product is free from harmful foreign body contaminants or quality errors. This is a world where consumers never experience issues with their end products and manufacturers and brands never worry about their business reputations, or worse, legal action.

Sounds perfect, right? This utopia doesn’t have to be so far off.  With the right steps and with advanced product inspection solutions, manufacturers can go a long way in producing high quality and safe goods.

Learn even more about due diligence in our white paper, "The Principles of Due Diligence for Food Safety and Quality Control". 

What is due diligence in manufacturing?

The concept of due diligence is the actual act of carrying out comprehensive quality control checks to verify that a product is safe. This includes that a product is free from foreign body contaminants, at the correct weight and accurately labeled.

The Technology

The Technology

Product inspection technology is the key to maintaining standards of product quality and safety while boosting productivity. Advanced metal detection technology serves as a critical tool in identifying ferrous and non-ferrous metal and stainless-steel contaminants that could pose significant risks to consumers. Smart x-ray inspection empowers manufacturers to detect a wider range of foreign bodies plus simultaneously completing a variety of product integrity checks. Automated vision inspection systems act as vigilant guardians, meticulously examining product quality through visual analysis, detecting label defects and inconsistencies in the content on the label that might have eluded human eyes. Meanwhile, high-performing precision checkweighers play a pivotal role in verifying product weight compliance, averting instances of under-fills or over-fills that could compromise consumer satisfaction or regulatory adherence.

Improving Due Diligence through Checkweighing in the Food Industry

The responsibility for food manufacturers to produce safe and high-quality products is constantly growing. In order to meet the retailer specifications, it's imperative that they take all necessary precautions to ensure their products are in compliance with weighing regulations and are contaminant-free. This is where the METTLER TOLEDO Due Diligence Kit comes in, providing integrated monitoring options that meet the safety and quality assurance regulations in the food industry for product inspection.
The Due Diligence of the Machines

The Due Diligence of the Machines

While the product inspection machines themselves are designed for accuracy, their due diligence relies on certain security factors. A number of features can be integrated into product inspection solutions to provide a series of checks that confirm that the systems are operating correctly at all times, for example, reject confirmation unit, reject check sensors etc. Password-controlled reject bins provide an added layer of security, preventing unauthorized access and maintaining the integrity of the inspection process. Regular calibration and maintenance help ensure that machines remain accurate and reliable over time, minimizing the risk of false rejects or missed defects. Training and competency programs for operators are crucial to effectively utilize the machines, maximizing their potential and avoiding human errors.

Product inspection technologies can also be connected to quality inspection data management software to complete real-time monitoring of inspection results. This allows manufacturers to identify trends, detect anomalies and take corrective actions promptly. 

The Due Diligence Defense

The Due Diligence Defense

Due diligence in product inspection serves as a robust defense mechanism, protecting consumers and preserving brand reputation. Compliance with industry regulations and standards is a fundamental aspect of due diligence, making sure that products meet the required safety and quality benchmarks. Maintaining traceability and documentation throughout the inspection process allows manufacturers to demonstrate compliance and facilitate recalls or investigations if necessary. By adopting risk mitigation strategies, such as implementing multiple inspection technologies and establishing comprehensive quality control processes, manufacturers can minimize the potential for errors and hazards. Continuous improvement is equally important, as manufacturers should embrace feedback, invest in research and development and continuously enhance their inspection systems and processes to stay ahead of emerging challenges.
