How to fix: Mop Water Disposal — Improper Location or Method

Mop water, floor washing water, or other liquid waste was disposed of in a food prep sink, handwashing sink, or other unapproved location rather than the mop sink or utility sink.

What this violation means

FDA Food Code 5-501.116 requires that liquid waste — including mop water, floor washing water, and similar wastewater — be disposed of in a mop sink (service sink) or utility sink designated for that purpose. Pouring dirty mop water down a food prep sink contaminates the sink and the drain area with bacteria and chemical residue. Pouring it down a handwashing sink removes a critical food safety fixture from use and potentially contaminates it. Inspectors check whether a mop sink is present, accessible, and being used correctly, and whether staff are aware of the proper disposal procedure.

Step-by-step: how to fix this before re-inspection

1Train all cleaning staff to dispose of all mop water and liquid waste exclusively in the designated mop sink or utility sink — never in prep sinks or handwashing sinks
2Post a sign above the mop sink indicating it is the designated disposal location for all liquid waste
3If no mop sink is present, work with your local health department on a compliant wastewater disposal plan — a plumber may need to install one
4Ensure the mop sink is accessible at all times — not blocked by stored equipment or chemicals
5Clean the mop sink itself weekly to prevent odor and bacterial buildup

What the inspector rechecks at re-inspection

WHAT THE INSPECTOR CHECKS

Inspectors do not just look at the surface. For this violation, expect them to verify:

☐Checks that a mop sink or service sink is present and accessible on the premises
☐Asks staff where they dispose of mop water and floor washing wastewater
☐Looks for mop buckets near food prep or handwashing sinks, which may indicate improper disposal
☐Inspects the mop sink area for cleanliness and verifies it is used exclusively for waste water
☐Checks that floor drains are present and functional in areas that require wet cleaning

How to prevent this violation from recurring

Include mop sink and wastewater disposal procedures in new employee onboarding
Post disposal procedures in the janitorial area as a reference
Conduct a monthly walk-through of janitorial practices with your cleaning staff
