Common mistakes when implementing ISO standards

One of the most common but underestimated mistakes is the implementation of ISO as a separate system that is parallel to real production.

On paper, everything looks perfect: there are regulations, cleaning schedules, instructions, and control points. However, within a shift, production operates according to different rules, influenced by the pressure of the plan, limited cleaning time, equipment specifications, and human factors.

This is particularly evident in sanitary cleaning. For example, the regulations may require a certain amount of time for the cleaning solution to be effective, but the line is started earlier due to a tight schedule. Or the cleaning scheme is formally approved, but employees adapt it because certain areas of equipment are difficult to clean well within the existing process.

In practice, such areas become a source of constant sanitary problems. Even with strict adherence to regulations and the use of high-quality chemicals, the operator cannot guarantee uniform treatment of all surfaces.

This is especially difficult with foam washing. If the area is not adapted for this method, the foam is distributed unevenly. Some areas remain dirty even after several cycles.

One of the most common mistakes when implementing ISO standards in food production is replacing actual sanitization with visual inspection.

In practice, this means that if the surface is covered with foam and appears clean, the process is considered complete. This approach quickly becomes habitual because it is convenient: it is easy to check, there is no need for measurements, and it does not complicate the work of employees.

At the same time, overprocessing has direct consequences that are often overlooked in economic accounting:

• accelerated wear of seals, hoses, and connections;
• increased maintenance costs for equipment;
• disruption of the production process;
• decreased overall shift efficiency.

One of the hidden problems when implementing ISO in food production is the design of a system that is focused on a «stable and trained employee.» However, in reality, it is almost impossible to find such an ideal employee on the production line.

In the documentation, the processes are described in a logical and consistent manner, with the use of instructions, regulations, sanitary treatment schemes, and checklists. It is assumed that the operator is well-versed in the sequence of actions, understands the critical parameters, and strictly follows the established procedures.

One of the main mistakes when implementing ISO in food production facilities is shifting control from the quality of the result to the formal implementation of sanitary procedures.

In most systems, this seems correct: the washing has been carried out, the checklist has been completed, the parameters have been marked, and there are no deviations. From a documentation perspective, everything looks fine.

However, the main question remains unanswered: was the same result achieved after each sanitary treatment?

In the standard interpretation, ISO systems are more focused on confirming the execution of procedures than on measuring the stability of results. This is particularly evident in sanitary processing, where visual inspection and checklists are insufficient to assess the actual quality of cleaning.

In many food production facilities, there is a paradoxical situation: the company successfully passes external ISO audits, but internally, it feels that the sanitary system is not proactive, but rather constantly reactive to problems.

Formally, all requirements are met: there are regulations, logs are filled, and sanitary procedures are carried out according to the schedule. From the point of view of the audit, the system appears to be manageable and in line with the standards.

However, in practice, quality management often begins only after a problem arises, whether it is a remark from an auditor, an internal discrepancy, or, in extreme cases, a complaint.

The implementation of ISO in food production is often perceived as a completion – the certificate confirms that the system works. But in practice, compliance with the standard does not guarantee the manageability of sanitary processes.

Most errors are united by one reason – the gap between formal requirements and the real logic of production. When ISO exists separately from technologies, sanitary systems and equipment, the system relies on compromises, manual solutions and constant compensations.
