Thus, while ISO 18593 specifies how to sample, the where and how often must be determined by the food business operator through a risk‑based approach.
Once collected, samples must be handled carefully to prevent target microorganisms from dying or multiplying before analysis.
provides internationally agreed-upon "horizontal methods"—meaning they are designed to be widely applicable across different types of food products and animal feeding stuffs—for sampling surfaces. It offers clear guidance on how to properly collect samples using techniques like contact plates, swabs, sponges, and cloths. The goal is to detect and count any viable microorganisms present, which is a fundamental activity for both routine hygiene monitoring and investigating potential contamination sources. The latest version is the second edition, ISO 18593:2018 , which was confirmed in 2023. Thus, while ISO 18593 specifies how to sample,
Unlike vertical standards that target specific pathogens or products, horizontal standards offer universal protocols applicable across diverse matrices. ISO 18593 ensures that surface sampling data is consistent, reproducible, and legally defensible worldwide. The Importance of Environmental Monitoring

ISO 18593 is an international benchmark that provides detailed, horizontal methods (applicable across a broad range of sectors) for sampling surfaces in the food chain environment. It is designed to detect and enumerate viable microorganisms, including pathogens and spoilage organisms, ensuring that the data derived from environmental monitoring is reliable and reproducible.
: Any item in contact with food or likely to be a contamination source, including premises and operators. Exclusions cover cleaning validation, primary production sampling (see ), or carcass sampling (see ISO - International Organization for Standardization Key Sampling Techniques Unlike vertical standards that target specific pathogens or
Ensure reliable transport coolers and ice packs are ready before starting the sampling round. Conclusion
Agar plates pressed directly against flat surfaces; useful for quantitative estimation but limited by surface shape.
: When sampling surfaces immediately after cleaning and disinfection, it is essential to use a neutralizer in the sampling medium to prevent residual disinfectant from killing the microorganisms before they can be recovered.
Searching for is your first step toward defensible, reliable environmental monitoring. This document is not just a bureaucratic requirement—it is a technical shield against false hygiene passes and unexpected outbreaks.
