Good detergents don’t work – what lies on the invisible side

In the food industry, hygiene problems are often associated with the wrong detergent. However, practice shows that in many cases microbiological deviations, shorter product shelf life, or even product quality issues occur not because of the product itself, but due to incorrectly performed cleaning processes.

In such cases, bacteria remain on surfaces or inside equipment, and the problems usually become visible only during laboratory tests or after the product has already reached the market.

In practice, three main causes are most common:

• Residues on surfaces

Layers of fats, proteins, or other organic residues create a favorable environment for bacterial growth, even when the surface appears visually clean.

• Incorrectly selected cleaning solutions

When an unsuitable detergent is used or it is applied to the wrong surface, contaminants are only partially removed, and deposits build up inside the equipment.

• Failure to follow procedures in daily practice

When hygiene actions are performed differently each shift, parameters are not controlled, or established instructions are not followed, results become inconsistent and bacterial contamination increases.

Conclusion: hygiene results depend not only on the chosen detergent, but also on how it is used. Properly selected products work effectively only when clear processes, correct parameters, and consistent daily routines are followed.
