Clinically Tested Clean

Professionally tested

BagWasher results were professionally tested for accuracy with
Element Laboratories, Portland, OR

Multiple tests were done throughout the past 4 years. The following results were from May 2023 tests, from two separate meats. Chicken and Pork, marinated.
We sent the dirty bags and the bags that were washed by BagWasher in the dishwasher.

These results conclusively demonstrate the effectiveness of BagWasher in removing extreme levels of microbial contamination, even from bags exposed to high-risk food residues like marinated meats and sauces. Here's what the data proves:

Scientific Validation of Cleaning Power
Test Bag Description CFU/g Before Washing CFU/g After BagWasher Reduction Factor
Spices & Olive Oil Marinated Chicken 280,000,000 <10 >28 million-fold
BBQ Sauce & Spices with Pork Loin 270,000,000 10 27 million-fold

What This Proves
  • Extreme Contamination Can Be Neutralized:
    These bags started with hundreds of millions of CFU/g, indicating heavy microbial contamination—comparable to raw meat handling surfaces.
  • BagWasher Achieves Near-Sterile Results:
    After washing, both bags showed 10 CFU/g or less, which is well below food-safe surface thresholds (often <100 CFU/g). This level of cleanliness is exceptional for reusable consumer packaging.
  • Consistent, Reliable Sanitation:
    The results were replicated across two different food types and contamination profiles, proving BagWasher’s broad-spectrum efficacy.
  • Supports Retail and Regulatory Confidence:
    These findings provide quantitative proof that BagWasher meets or exceeds hygiene expectations for reusable packaging in grocery, food service, and consumer use.

BagWasher Cleanliness Validation: Lab-Tested Hygiene You Can Trust

Overview:
Zip-top style bags washed with BagWasher were tested for microbial cleanliness using Aerobic Plate Count (APC) analysis. The results confirm BagWasher’s effectiveness in delivering hygienically clean bags suitable for reuse in food-safe environments.

Test Result:
  • Aerobic Plate Count: 10 CFU/g
  • Interpretation: This ultra-low count indicates minimal microbial presence, well below common hygiene thresholds. For comparison, surfaces with <100 CFU/g are often considered clean in food packaging and handling standards.

Why It Matters:
  • Food Safety: Reduces risk of cross-contamination from zip-top style bags.
  • Consumer Confidence: Demonstrates BagWasher’s commitment to hygiene and sustainability.
  • Retail Readiness: Supports compliance with health standards for reusable packaging.

Testing Details:
  • Method: Aerobic Plate Count (APC)
  • Units: CFU/g (colony-forming units per gram)
  • Sample: Bags washed using BagWasher
  • Lab: Element Labs, Portland, OR 97220

Conclusion:
BagWasher delivers lab-verified cleanliness, making it a safe, sustainable solution for reusable bag programs in retail, food service, and consumer use.
