Contact time The time span during which the item is in contact with the detergent or the
disinfectant.
Enzymes Molecules, which are added to cleaning agents to ease the removal
of specific organic material. Assures same cleaning effect at a lower
temperature.
Disinfectant Usually a chemical agent that destroys harmful microorganisms but might
not kill bacterial spores.
Disinfection Thermal or chemical destruction of microorganisms. Disinfection is
less lethal than sterilisation, because it destroys most recognised
microorganisms but not necessarily all microbial forms (e.g. bacterial
spores).
Detergent A cleaning agent that has no antimicrobial effect, but in diluted solutions
good cleaning properties.
EHEDG Abbreviation for the European Hygiene Engineering and Design Group.
EHEDG is a consortium of equipment manufacturers, food industries,
research institutes as well as public health authorities promoting safe
food by improving hygienic engineering and design in all aspects of food
manufacture.
Electro polishing Electro polishing is an electrochemical process by which the high points
within the microscopic surface texture are removed and the corners rounded.
This results in Reduced Product Adhesion, Ease of Cleaning and Improved
Corrosion Resistance.
Exposure time Period in a sterilisation/disinfection process during which the item is
exposed to the sterilant/disinfectant at the specific sterilisation/disinfection
parameters.
Flow path The path the sample flows from the tank or process equipment to the sample
recipient.
Germicidal The property of an agent to destroy microorganisms.
Microbial load The number and types of viable microorganisms with which an item is
contaminated; also called bioload or bioburden.
Microorganisms Animals or plants of microscopic size. As used in food and pharmaceutical
industries, generally refers to bacteria, fungi, viruses and bacterial spores.
Peracetic acid A commonly used disinfectant, which is efficient at low temperature and
short contact time. Relatively harmless as it decomposes into carbon dioxide
(CO
2
) and water (H
2
O).
Process media The product in the process equipment and the product from which a sample
is taken.
Representative sample A sample which when it reaches the laboratory is still identical to the process
media. A sample which is in no way contaminated or altered during neither
the sampling process nor the transport to the laboratory.
Sanitization The application of a chemical agent that reduces the number of bacterial
contaminants to a safe level as judged by the public health authorities. The
official sanitizer protocol indicates that 99.999% of the specific test bacteria
be killed in 30 seconds under the conditions of the test.
SIP Abbreviation for Sterilise-In-Place. The process of rendering a process
component (like a sampling valve) sterile without removing it from the
production line.
