What is Pseudomonas aeruginosa?
Pseudomonas aeruginosa is a Gram-negative bacterium associated with healthcare-associated infections such as pneumonia, bloodstream infections, surgical site infections, and device-associated infections. It thrives in moist environments including sinks, drains, respiratory equipment surfaces, and other wet or frequently touched areas. Some strains are multidrug resistant, making environmental cleaning and EPA-registered disinfection essential to reduce surface transmission risk.

Can OxiTab Disinfectant Tablets Kill Pseudomonas aeruginosa?
Yes. OxiTab’s EPA registration includes bactericidal efficacy against P. aeruginosa on hard, non-porous surfaces when mixed and applied according to the label.
EPA-Registered Kill Claims for Pseudomonas aeruginosa
- Concentration: 1076 ppm
- Minimum Contact Time: 4 minutes
- Does OxiTab kill P. aeruginosa? Yes, when used as directed.

How to Sanitize Against Pseudomonas aeruginosa Using OxiTab
- Pre-clean visible soil: Remove organic debris to improve disinfectant performance, especially around sinks, drains, and splash zones.
- Prepare the solution: Dissolve 1 OxiTab tablet (13.1 g) in 1 gallon of water to reach the labeled disinfection strength of about 1076 ppm.
-
Apply the solution:
- Spray bottle: faucets, handles, bed rails, counters, treatment chairs, carts
- Mop bucket: floors in patient rooms, procedure areas, restrooms, locker rooms
- Wipes or cloths: small fixtures, touch screens exteriors, keyboards and mice exteriors
- Electrostatic sprayer: broad coverage in hallways, waiting rooms, and common areas
- Contact time: Keep surfaces visibly wet for at least 4 minutes.
- After treatment: Allow to air dry or wipe for appearance after the contact time is met.
- Solution management: Effective up to 24 hours. Store closed and prepare fresh daily.
- PPE and waste: Use appropriate PPE; handle and dispose of materials per facility policy and local regulations.
How Pseudomonas aeruginosa Spreads and How Long It Survives
P. aeruginosa spreads via direct contact with contaminated water, surfaces, or equipment, and by hands that touch contaminated sites then patient care items. It favors moisture and can form biofilms on surfaces that are wet or frequently splashed, making routine disinfection of high-risk zones crucial.
Pseudomonas aeruginosa Survival Times by Surface
1. Hard, non-porous surfaces
- Stainless steel and plastic: Can persist from days to weeks in moist environments, especially near sinks and splash zones.
- Glass and laminate: Days under favorable humidity and organic soil conditions.
- Ceramic and sealed stone: Multi-day survival, particularly around bathrooms and wet areas.
2. Porous and softer surfaces
- Wood (finished): Typically shorter survival than on non-porous materials, but moisture and cracks can prolong persistence.
- Fabric and upholstery: Hours to days when damp; dry conditions shorten survival.
- Paper products: Hours under typical indoor conditions.
3. Extended persistence drivers
- Moisture and residual water: Strongly favor survival and biofilm formation.
- Organic load: Soil can shield bacteria and reduce disinfectant performance if not removed during pre-cleaning.
Surface Survival Times Chart
| Surface Type | P. aeruginosa Survival Time |
|---|---|
| Stainless Steel & Plastic | Days to weeks (especially in moist areas) |
| Glass & Laminate | Days |
| Ceramic & Sealed Stone | Multi-day |
| Wood (Finished) | Hours to days (longer if damp) |
| Fabric & Upholstery | Hours to days (moisture dependent) |
| Paper Products | Hours |

Why Does Pseudomonas aeruginosa Live So Long?
P. aeruginosa can produce protective biofilms that shield cells from environmental stress and basic cleaning. Moist niches like sink rims, overflow drains, and splash zones facilitate survival and regrowth. Pre-cleaning to remove biofilm buildup and using an EPA-registered disinfectant at the labeled strength and contact time are essential for reliable control.
Preventing Surface Transmission
- Clean first, then disinfect with OxiTab at 1076 ppm for 4 minutes.
- Target wet zones: sinks, faucets, splash areas, tubs, and shower rooms.
- Increase frequency for high-touch points: bed rails, call buttons, carts, doorknobs, switches.
- Dry surfaces after routine use when feasible; address leaks and standing water promptly.
- Disinfect shared equipment between uses and label clean/dirty storage.

Symptoms of Pseudomonas aeruginosa Infections
- Common presentations: wound infections, urinary tract infections, otitis externa, skin and soft tissue infections
- Serious complications: pneumonia, bloodstream infections, sepsis, especially in immunocompromised or ventilated patients
Reference: MedlinePlus – Pseudomonas Infections
Who Is Most at Risk?
- Hospitalized and ICU patients (especially with ventilators, catheters, or wounds)
- Long-term care residents with chronic conditions
- People with burns, cystic fibrosis, or immunocompromise
- Facilities with persistent moisture issues (sinks, drains, spas, wet rooms)
Prevention Best Practices (By Environment)
- Healthcare: routine and terminal cleaning; disinfect shared equipment between uses; address wet environmental reservoirs (sinks, splash zones)
- Long-term care: scheduled bathroom and sink area disinfection; hand hygiene reinforcement
- Education & childcare: clean and disinfect restrooms, nurse stations, and locker rooms; manage spills promptly
- Hospitality & fitness: disinfect showers, pool/spa areas, locker rooms, benches; ensure proper drainage and drying
- Salons & spas: disinfect wash stations, sinks, chair arms, and non-porous tools between clients
Why OxiTab is the Safer Choice
- Non-hazardous: safer to handle than bleach or Quats (QACs)
- No residue: leaves a clean finish without sticky films or harsh odors
- Simple and affordable: tablet dosing makes mixing easy and consistent
FAQs About Pseudomonas aeruginosa
Q: What disinfectant kills Pseudomonas aeruginosa?
A: OxiTab kills Pseudomonas aeruginosa with EPA-registered efficacy at 1076 ppm and 4 minutes contact time.
Q: Where does P. aeruginosa persist the most?
A: Wet zones like sinks, drains, and splash areas; high-touch surfaces near water sources; and inadequately dried equipment.
Q: Are Quats effective against P. aeruginosa?
A: Some QAC-only products may be less desirable for wet biofilm-prone areas. OxiTab offers non-hazardous, label-verified efficacy when used as directed.
Q: Does OxiTab leave a strong chemical odor?
A: No. OxiTab leaves a clean finish without harsh residue or strong lingering odors.
