Good for qualitative analysis, but can be less efficient at removing bacteria from smooth, flat surfaces compared to wipes. 2. Contact Plate Method (RODAC Plates) Best For: Flat, smooth, and dry surfaces.
The standard, titled "Microbiology of the food chain — Horizontal methods for surface sampling," establishes standardized procedures for detecting and counting culturable microorganisms on surfaces within the food industry. It is a critical guideline for environmental monitoring programs aimed at preventing food contamination. Core Sampling Techniques
Microbiology of the food chain — Horizontal methods for surface sampling
Surface Sampling for Listeria monocytogenes in Food Production - Journal of Food Protection. ISO 11290-1:2017 Microbiology of the food chain.
The standard outlines three main techniques for surface sampling, each suited to different surface types and contamination levels. 1. Contact Plate Method
The standard outlines specific validated methods for harvesting microorganisms from surfaces. The choice of method depends on the surface texture, accessibility, and the target organism density. 1. Contact Plate Method
