Contact plates (often called Replicate Organism Detection and Counting, or RODAC plates) are rigid dishes filled with agar that protrudes slightly above the rim.
The International Standard ISO 18593 provides guidelines for the microbiological analysis of food and animal feed products. The standard, titled "Microbiology of food and animal feeding stuffs — Horizontal method for enumeration of microorganisms", was first published in 2004 and was last updated in 2020.
