ISO 18593:2018 PDF Download

ISO 18593:2018 is a standard that outlines the horizontal methods for surface sampling in the field of microbiology of the food chain. It provides guidelines on sampling techniques using various tools such as contact plates, stick swabs, sponges, and cloths to detect and enumerate culturable microorganisms on surfaces.

The standard defines the "environment" as any item that comes into contact with the food product or is likely to be a source of contamination or recontamination, including materials, premises, and operators. However, it does not cover the validation of cleaning and disinfection procedures.

Additionally, ISO 18593:2018 specifies that it does not apply to sampling techniques for primary production samples, which are covered by ISO 13307, nor does it cover sampling techniques for carcasses, which are covered by ISO 17604. Sampling techniques for the analysis of noroviruses and hepatitis A viruses are also excluded and are covered by ISO 15216-1.

It is important to note that the standard does not provide specific guidance on sampling frequency, the number of sampling points, or the need to rotate sampling points. These factors are determined on a case-by-case basis.
