This is a critical tool that reduces incident response times from hours to minutes, eliminates “paper HACCP”, and ruthlessly enforces expiry dates on the shop floor.
Digital Traceability and HACCP: Always ready for an audit
The greatest value of MES for the food industry is immediate traceability (traceability) and the digitisation of quality processes. Standards such as IFS or BRCGS require full “one step up, one step down” genealogy, which in multi-ingredient production using rework is a nightmare to track in paper registers.
The MES system delivers this in real time, offering:
- Instant Mock Recall: Generating a full mass balance and a list of customers who received a suspect batch is down to just a few clicks.
- Electronic CCP/CP: Measurements from metal detectors, scales, or pasteurisers (temperature, time, pH) are recorded automatically.
- System locks: If critical limits are exceeded at a CCP point, the system automatically blocks the batch, preventing it from moving to the next stage without a decision under the CAPA procedure.
- Full Audit Trail: Every action in the system is assigned to a specific operator, building a reliable production history for auditors.
Batch management and strict FEFO enforcement
The specific nature of Food & Beverage (F&B) production is primarily a race against time and expiry dates. ERP works well for planning, but it is MES that manages reality on the so-called gemba.
In a food warehouse, FIFO rarely works – what matters is FEFO (First-Expired, First-Out).
How MES optimises batch management:
- Enforces raw material retrieval on operator terminals strictly in accordance with the FEFO rule.
- Blocks the possibility of using a batch that does not comply with the quality status (e.g. one that is in quarantine).
- Manages flexible shelf life calculation (shelf life) depending on the target market and guidelines from the ERP.
- Integrates with labellers and scales, eliminating the risk of a discrepancy between the expiry date in the system and the print on the packaging.
Recipes and Allergens under full control
In many plants, actual knowledge of recipes still lives in foremen’s notebooks. MES introduces the concept of a Master Recipe – a centrally managed, approved template that is precisely translated into the parameters of a specific production line.
Thanks to this, the system automatically:
- Controls the consumption of premixes, additives, and allergens, supporting the planning of production and cleaning sequences.
- Records rework as a fully-fledged process component, monitoring its maximum limits in a batch.
- Minimises the risk of product recalls by ensuring absolute consistency between the raw materials used and the information on the label.
Where ERP ends and MES begins
To fully understand the role of MES, one must look at the system architecture in the plant. ERP operates at the financial and logistical level and takes a bird’s-eye view of production. MES “sits” directly above the lines, communicating with machines (PLCs), scales, and people.
Comparison of system roles:
| Area | ERP System | MES System (F&B) |
| Perspective | Months, weeks, days | Shifts, hours, minutes, seconds |
| Tracking object | SKU, production order | Specific batch (lot), trolley, vat, pallet |
| Quality | Defect reporting, general statuses | CCP control, deviation workflow, process locks |
| Execution | Issue from warehouse to production | Precise dosing according to Master Recipe, FEFO validation |
Checklist: How not to ruin an MES implementation in F&B
An MES implementation is not an IT project. It is a fundamental change in how technologists, the quality department, and line operators work. The most common mistake is focusing solely on performance optimisation (OEE) and ignoring food safety modules, which are crucial for F&B, in the first phase of the project.
Best practices and questions for the vendor:
- Clean up your Master Data: Do not transfer Excel mess into the new system. Standardising recipes, expiry date rules, and statuses is a sine qua non condition.
- Check support for Mock Recall: Ask the vendor exactly how many clicks are needed in their system to generate a full list of customers linked to a specific batch of defective raw material.
- Start with a high-risk pilot: Choose a production line where allergen control, short shelf lives, and CCPs are of the most critical importance.
- Involve technologists and QA from day one: A system defined solely by maintenance and IT departments will not solve the quality issues that auditors care about.
From audit theory to production practice: iPLAS
Awareness of how a safe and efficient food plant should operate is fundamental, but real change requires the right tool. One that will not overwhelm the organisation with redundant features, but will precisely address its bottlenecks. It is in response to these challenges that iPLAS was created – a modern platform developed by engineers from SPIID (a winner of the Forbes Diamonds 2025 ranking). The system retrieves data in real time directly from machine controllers and manual stations, instantly turning it into clear reporting dashboards available 24/7 in a web browser. Its greatest strength, however, is its pragmatic modularity. Instead of implementing a heavy, monolithic system, you invest in the core and choose only those modules you need at any given moment – from precise OEE monitoring and downtime reduction to managing specific production cells. It is a solution that takes the paperwork off your team’s shoulders and grows flexibly with your plant.
