Ideal for sampling large surface areas (typically > 100 cm²) to estimate total microbial load. Significant Updates in the 2018 Edition
The agar is pressed directly against the test surface with steady, uniform pressure for approximately 10 seconds.
ISO 18593:2018 forms part of a family of standards. It is technically equivalent to and has been adopted as identical national standards in many countries, such as BS EN ISO 18593:2018 (UK), NF EN ISO 18593:2018 (France), DIN EN ISO 18593:2018 (Germany), and I.S. EN ISO 18593:2018 (Ireland). Ideal for sampling large surface areas (typically >

It is important to note that at recovering both viable and culturable bacteria from biofilms—the slimy microbial layers that can form on surfaces. The choice often comes down to which tool is most practical for the specific surface being tested. It is technically equivalent to and has been

Contamination of food products often occurs through contact with surfaces. Pathogens can survive on processing equipment, floors, and walls for long periods. These microorganisms form biofilms that resist routine cleaning and disinfection.
For any professional seeking to implement ISO 18593, obtaining the official, verified PDF is essential to ensure access to the complete, legally correct, and up-to-date text. Using unofficial or outdated copies can lead to non-compliance, flawed procedures, and inaccurate data.
ISO 18593 describes itself as a meaning it is designed for universal application. It is equally effective for testing surfaces that come into direct contact with food, like cutting boards and machinery, and those that do not, such as walls, floors, or even a worker's gloves. The standard explicitly states it does not cover the validation of cleaning procedures, nor does it apply to sampling primary production samples (e.g., live animals) or carcasses, which are covered by other specific ISO standards.
