BOISE, ID — In light of the launch of the ISSA Clean Standard, the Healthy Facilities Institute (HFI) is providing ATP Sampling Tips, according to a press release.

"ATP swabs are widely used in the cleaning industry to perform an Integrated Cleaning and Measurement™ (ICM) program and are part of the ISSA Clean Standard… [However] swab sampling [can have] a very large number of variables that can affect the meaning of the contamination data derived from swab samples…" said Dr. Jay Glasel, Professor Emeritus in the Department of Microbial, Molecular and Structural Biology at the University of Connecticut Medical School in Farmington, Connecticut, and Managing Member and Founder of Global Scientific Consulting LLC.

"For example, if the swab sampling pickup and deposit efficiencies vary greatly from sample to sample, the data becomes meaningless no matter how many samples we obtain even though the samples are scored using a perfectly accurate instrument — for example, an ATP luminometer. This is another example of 'garbage in, garbage out,'" Glasel added.

In order to ensure consistency in ATP measurement, the selection of the actual high touch points that will be tested using an ATP device should be done randomly and in a manner that ensures that selected areas are located throughout the facility, the release stated.
