International Standard Iso 18593 Microbiology Of Food And Animal Pdf Info
You have SOPs for cleaning, but how do you know they work? ISO 18593 provides the verification data. If a deep clean is performed, post-clean sampling should show a significant reduction in Total Viable Count (TVC).
ISO 18593 (specifically titled Microbiology of the food chain — Horizontal methods for surface sampling) is an international standard that outlines the technical specifications for sampling surfaces in food production environments.
The standard provides a "horizontal method," meaning the techniques described are applicable across a wide range of food industries—from animal feed to human food production—rather than being specific to just one product type. You have SOPs for cleaning, but how do you know they work
The standard details three primary methods for detecting and enumerating microorganisms on surfaces:
Q1: Can I use ISO 18593 for viral sampling (e.g., norovirus)? A: No. The standard is designed for bacteria and fungi. Viruses require molecular swabbing methods (e.g., ISO 15216). Limitations: Cannot be used on porous wood, cracked
Q2: Does the standard give pass/fail limits? A: No. ISO 18593 only defines how to sample. Your company or regulator sets the microbiological limits (e.g., <10 CFU/plate for food contact surfaces).
Q3: Is ATP bioluminescence covered by ISO 18593? A: No. ATP is a rapid hygiene method, not a microbiological one. However, you can use ISO 18593 swabs to periodically validate your ATP system. A "horizontal" standard means a small laboratory testing
Q4: I work only with animal feed (dry pellets). Does this apply? A: Yes. The "food chain" includes animal feeding stuffs. However, for dry, dusty surfaces, you may need to modify swab wetting – the standard provides guidance for this.
A "horizontal" standard means a small laboratory testing animal feed can use the same method as a multinational meat processor, allowing fair trade and shared data.
