Hygiene audit

A complete hygiene audit…
…for controlled cleaning of your installations!

Realco/Realzyme offers a Hygiene Audit that aims to identify potentially critical equipment and confirm or rule out the presence of contamination in the installation.

Realco/Realzyme casts an unbiased eye over the methods and cleaning protocols used.

This complete hygiene audit offers:

1) Six (6) sampling methods/analysis of ten (10) points (critical areas)

a. ATP test
The ATP test estimates the quantity of organic residue and the microbial flora.

b. Dipslides

A dipslide is a plastic slide covered in a nutrient agar. It is applied to the surface to be tested.
It will reveal traces of microbial contamination.

Larmes dipslides

c. Detecting slime-forming bacteria (SLYM-BART®)
This method aims to detect the presence of microorganisms that are capable of forming biofilms.



d. Turbidity in SLYM-BART® tubes
Quantified in terms of Nephelometric Turbidity Units. The turbidity depends on the extent of growth of the bacteria that form the biofilm.

e. Other observations of SLYM-BART® tubes
Observation of SLYM-BART® tubes under UV light reveals a contamination via Pseudomonas sp. fluorescens (classic germs found in biofilm contaminations). Other observations can also be made.


This tool is used to measure the performance of cleaning teams. This patented technology colors areas that are inadequately cleaned with a blue coloration, so that management can ensure effective cleaning of the food-preparation areas.

2) A constructive look at the protocols implemented.
