One of the most critical aspects highlighted in ISO 18593 is the use of neutralizing agents. If a surface was recently cleaned, chemical residues (like chlorine or quaternary ammonium) can inhibit microbial growth on the test media. This leads to "false negatives." The standard requires specific diluents to neutralize these chemicals immediately upon contact, ensuring the final count accurately reflects the viable microorganisms present.

ISO 18593 is the international standard governing horizontal methods for sampling techniques from surfaces in the food chain environment. It provides a standardized framework for testing surfaces using contact plates, swabs, and sponges to detect and enumerate viable microorganisms. This protocol is essential for food manufacturers, laboratories, and safety auditors to ensure hygiene control and prevent cross-contamination. Scope and Application iso 18593 pdf
