The standard outlines several validated techniques for retrieving microbial samples from various surface types. 1. Contact Plate Method Smooth, flat, non-porous surfaces.
: Sampling at the farm level is covered by ISO 13307.
ISO 18593 provides practical, standardized methods for surface sampling in the food chain, critical for validating sanitation, monitoring hygiene and reducing microbial risks. Effective implementation requires selecting suitable sampling devices, validating recovery, and integrating results into a risk-based food safety management system. : Sampling at the farm level is covered by ISO 13307
By adhering strictly to the verified guidelines of ISO 18593, food manufacturers can build robust Environmental Monitoring Programs (EMPs) that safeguard public health and preserve brand integrity.
: Inoculating selective culture media or performing rapid detection tests based on the specific target pathogens. Importance of a Verified PDF Version By adhering strictly to the verified guidelines of
Adherence to ISO 18593 moves an organization beyond visual inspection. While a surface may look clean, it can harbor pathogens like Listeria monocytogenes or Salmonella .
ISO standards are often adopted as identical national standards. You can purchase the PDF from your local NSB, which often results in a shorter delivery time. Below is a table listing some NSBs where you can purchase ISO 18593:2018: While a surface may look clean
The standard outlines specific techniques based on the type of surface being tested, its accessibility, and the target organism. 1. Contact Plates
The standard mandates that transport media must neutralize residual disinfectants. The verified PDF lists approved neutralizers:
Once samples are collected, they must be transported to the laboratory under refrigerated conditions ( 1∘C1 raised to the composed with power C 8∘C8 raised to the composed with power C ) and processed within 24 to 48 hours.
