No. ISO 18593 states surfaces should be dry and visibly clean. Heavy soil (fat, blood) will ruin agar absorption. Clean surfaces first, then sample.

In the realm of food safety, what you cannot see can indeed hurt you—and your consumers. The silent transfer of pathogens such as Listeria monocytogenes , Salmonella , and E. coli often begins not in the raw product itself, but on the surfaces that touch the product. From conveyor belts and slicing knives to the gloves of food handlers, surface contamination is a critical vector for foodborne illness.

Use the chosen method (swab, sponge, contact plate) to cover the defined area.

The swab method is a versatile technique for irregular, porous, or hard-to-reach surfaces like corners, crevices, valves, or equipment. A sterile stick swab (e.g., cotton or nylon) is moistened in a neutralizing solution. It is then rubbed several times over a defined area, rotating it to trap microorganisms. The swab is returned to a transport tube, and in the lab, it is vortexed to release the organisms. The result is expressed as CFU per swab or per cm².

When reviewing the official ISO 18593 PDF document, you will find it systematically structured into key technical sections: Defines the boundaries of the horizontal method. and in the lab

: Ensure that the swabs, plates, or sponges you purchase are explicitly validated for recovery rates and do not contain toxic components that kill bacteria.

A petri dish filled with agar media (contact plate) is pressed directly onto the surface.
