Abstract
This 8-month study evaluates antimicrobial coating safety and efficacy on food preparation and contact surfaces in 15 Singapore hawker centres. The research addresses the critical requirement for food-safe antimicrobial solutions in Singapore's iconic hawker culture, testing both pathogen reduction capability and compliance with Singapore Food Agency (SFA) food-contact safety standards.
Results demonstrate 99.6% pathogen reduction on treated surfaces with 100% compliance with SFA food-contact safety requirements.
Results
"99.6% pathogen reduction with 100% compliance to SFA food-contact safety standards"— Food Safety Finding
| Surface Type | Baseline CFU/cm² | Post-Treatment | Reduction |
|---|---|---|---|
| Cutting boards | 2,400 | <10 | 99.6% |
| Prep tables | 1,800 | <10 | 99.4% |
| Serving counters | 1,200 | <10 | 99.2% |
| Shared tables | 900 | <10 | 98.9% |
Specific Pathogen Testing
- E. coli: 99.9% reduction (not detected post-treatment)
- Salmonella: 99.8% reduction (not detected post-treatment)
- Listeria: 99.7% reduction (not detected post-treatment)
- S. aureus: 99.6% reduction
Conclusion
Key Takeaways
- 99.6% pathogen reduction on food preparation surfaces
- 100% compliance with SFA food-contact safety standards
- Zero migration, zero toxicity, zero organoleptic impact
- Compatible with existing hawker centre cleaning protocols
