The international standard ISO 18593:2018 , titled "Microbiology of the food chain — Horizontal methods for surface sampling," establishes a uniform framework for detecting and enumerating culturable microorganisms on surfaces within food industry environments. By providing standardized sampling techniques, it enables food business operators to identify potential contamination sources and verify the effectiveness of their hygiene protocols. Scope and Application
The International Standard ISO 18593 provides guidelines for the microbiological analysis of food and animal feed products. The standard, titled "Microbiology of food and animal feeding stuffs — Horizontal method for enumeration of microorganisms", was first published in 2004 and was last updated in 2020.

The Gulf Standardization Organization (GSO) has adopted the 2018 edition as . This is an identical adoption with no technical modifications, approved in October 2024, confirming that the 2018 version remains the state of the art in the Gulf region.
ISO 18593 is an international standard that specifies horizontal methods for sampling surfaces in the food chain environment using contact plates (also known as Rodac plates) and swabs. The key phrase "horizontal method" means it is designed to be applicable across various food sectors—meat, dairy, seafood, ready-to-eat meals, and animal feeding stuffs—without modification. Scope and Application The International Standard ISO 18593
A crucial aspect of ISO 18593 is the requirement to neutralize residues of sanitizers and disinfectants on sampled surfaces. The Role of Neutralizers

Contact plates (often Replicate Organism Detection and Counting, or RODAC plates) are plastic dishes filled with agar that creates a convex meniscus protruding above the rim.

The entire designated area is wiped firmly in vertical and horizontal directions.
: As the standard does not prescribe sampling frequency or locations, develop a risk‑based environmental monitoring plan that identifies critical sampling sites (e.g., food‑contact surfaces, nearby non‑food‑contact surfaces, and areas near drains or HVAC outlets).
