USDA, FDA, 3-A — what's the difference?
These three terms get used interchangeably, but they cover different things. FDA regulates the cleanliness and material safety of food-contact and food-processing facilities. USDA's Food Safety and Inspection Service (FSIS) inspects meat, poultry, and egg processing plants for sanitary design. 3-A Sanitary Standards is a third-party certification body specifically for dairy processing equipment and facility surfaces.
All three converge on the same flooring outcome: smooth, cleanable, non-porous, chemically resistant, properly drained, and detailed at every wall, drain, and equipment interface.
What inspectors actually check
Most flooring failures during audits aren't the field of the floor — they're the details. A urethane cement floor that looks pristine in the open will fail inspection because of one cracked cove or a pinhole next to a drain.
- ›Integral coved base — minimum 4″ at all wall transitions, sealed and crack-free
- ›Drain detailing — flooring rolled into drain bodies with no gap, no caulking visible
- ›Slope to drain — proper grade so water never ponds (typically 1/8″ to 1/4″ per foot)
- ›Equipment penetrations — sealed monolithically; no caulk-only details around legs and conduit
- ›No pinholes, cracks, or delamination anywhere in the wet zone
- ›Wall-floor junction with smooth transition radius (not a sharp 90°)
System recommendations by facility type
Different food and beverage operations need different floor chemistries. Here's what we install most often across the Western U.S.:
- ›Meat & poultry processing — urethane cement slurry 3/16″ minimum with integral cove
- ›Dairy / cheese processing — urethane cement with chemical-resistant urethane topcoat
- ›Breweries — urethane cement in production; high-build epoxy in dry packaging and warehousing
- ›Wineries — high-build epoxy in production with anti-slip aggregate; urethane cement in barrel rooms with caustic exposure
- ›Bakeries & dry food processing — flake or quartz epoxy 60–125 mil
- ›Commissary kitchens / commercial kitchens — quartz-broadcast urethane mortar at hot lines, epoxy in prep areas
The wall and ceiling matter too
USDA and FDA inspect more than the floor. Wall and ceiling surfaces in wet processing zones must be cleanable, mold-resistant, and free of seams that trap residue. We pair our flooring work with fiber-reinforced wall and ceiling coating systems that deliver a monolithic, cleanable surface from floor to ceiling.
If you're remodeling or building out a new processing room, scope the wall and ceiling system at the same time as the floor. Doing them together saves cost, reduces downtime, and ensures the wall-to-floor cove is truly monolithic.
Plan for downtime — but less than you think
A common myth is that compliance flooring takes weeks of downtime. With proper phasing, we routinely complete urethane cement installations in production rooms over a 48–72 hour weekend window, with the room cleared for sanitation by Monday morning. Larger projects are phased room-by-room so production never fully stops.
We've installed compliance flooring for meat plants, dairies, breweries, wineries, and commercial bakeries across California, Oregon, Washington, and Idaho. See our urethane cement flooring page or contact us with your facility's process zones and sanitation chemistries for a system spec.
