The standard, officially titled "Microbiology of the food chain — Horizontal methods for surface sampling," provides the essential framework for environmental monitoring in food production. Updated in 2018, this standard defines the "how-to" for collecting samples from equipment, floors, and walls to detect or count microorganisms like Listeria , Salmonella , yeasts, and molds. Scope and Application of ISO 18593
The standard details four primary methods for surface sampling, each suited to different surface types: The standard, officially titled "Microbiology of the food
It is used to estimate the level of contamination on surfaces that could represent a source of recontamination for the food itself. Standard Sampling Techniques carcass sampling (covered by ISO 17604)
Includes food processing plants, commercial kitchens, and animal feed facilities. The standard, officially titled "Microbiology of the food
This standard is a "horizontal method," meaning it applies across the entire food chain—from raw material processing to final packaging—rather than being restricted to one specific product.
It does not cover primary production (covered by ISO 13307 ), carcass sampling (covered by ISO 17604), or virus sampling (covered by ISO 15216-1).
