The current version replaced the first edition (ISO 18593:2004). The 2018 revision introduced several significant enhancements, expanding the standard's utility and reflecting advancements in industry practices.

The International Organization for Standardization (ISO) has published a standard for the microbiology of food and animal feeding stuffs, known as ISO 18593:2018. This standard provides a comprehensive framework for the microbiological analysis of food and animal feeding stuffs, ensuring the safety and quality of these products for human consumption and animal feed. The current version replaced the first edition (ISO
The swab is rubbed firmly over a defined area (usually 10 cm² to 100 cm²) in horizontal, vertical, and diagonal directions while rotating the stick. 3. Sponges
ISO 18593, titled "Microbiology of the food chain — Horizontal methods for surface sampling," provides standardized guidelines for detecting and enumerating microorganisms on surfaces. This horizontal standard applies across the entire food chain, encompassing food processing environments, animal feeding areas, and primary production sites. taking into account:
The standard describes several techniques for surface sampling, with the choice of method depending on the surface structure (flat, porous, complex) and the objective (quantitative vs. qualitative). A. Contact Plate Method (RODAC Plates) Used for flat, non-porous surfaces.
Are you targeting (like Listeria ) or hygiene indicators (like Total Viable Count)? flat surfaces compared to wipes.
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.
Label samples immediately and transport them to the lab under refrigerated conditions ( ) to prevent microbial growth or death [1].
