GmbH: Specialists for cleaning monitoring
In 1997 we asked ourselves: How can one neglect the
most important step when reprocessing surgical instruments?
If it´s not clean, it can´t be sterile
was a common phrase but there was not much standardisation,
quality assurance, or enough science behind cleaning
Ten years on PEREG GmbH
is the leading company for cleaning
monitoring when reprocessing surgical instruments.
This was achieved by believing in the importance of
cleaning and knowing the science behind it. In cleaning
we do not use standardised parameters as in sterilisation,
therefore monitoring a cleaning process needs to be
achieved in a different way: Tests for cleaning efficacy
must be adapted to the practical situation.
A test soil correlating to blood is one important
step but blood behaves differently in various cases
such as being cleaned from an ordinary steel surface
compared to cleaning the inside of an instrument.
Also blood residues after an inefficient cleaning
process do not have much in common anymore with fresh
blood. We took these important factors into consideration
and developed a special range of indicators and test
methods for washer-disinfectors, ultrasonic cleaners
and manual cleaning procedures:
-Indicator product line combines
a standardised test soil correlating to blood
with challenge devices simulating a range of surgical
The unique SonoCheck
verifies efficacy where ultrasonic
energy and cavitation is part of the cleaning
product line is especially designed to detect
traces of blood residue after a cleaning process which
is a clear sign for inefficient cleaning and a hygiene
detects protein residues in
applications where blood is not the main contaminant.
Backup is provided from the PEREG
GmbH laboratory where not only research
and development are carried out but
also detergents and cleaning methods are tested for
their efficacy. Validation and routine monitoring
of cleaning efficacy according to EN
ISO 15883 can now be handled safely. Patient
safety is our profession.
