If Listeria is present in your food production facility, it will most likely be found in your drains. The reason for this is that drains act as a collection points for most of the Listeria-contaminated water on site, and then provide the nutrients and moisture required for the Listeria to grow.
Even though cleaning drains is an unpleasant and complex task, it is critical for Listeria control. Dirty drains can be a source of Listeria contamination, and flooded drains can spread listeria via pools of contaminated water on the floor. Drains should (if possible) only be cleaned during production downtime, and you’ll need to give aerosols time to settle before rinsing and disinfecting your food contact surfaces.
