Bulk Soap Contamination

Studies show unsuspecting handwashers could be putting their health at risk when using bulk soap from open refillable soap dispensers

Recent studies conducted at the University of Arizona found that 23 to 25%1 of bulk soap dispensers may contain contaminated soap. Soap from contaminated bulk soap dispensers can put users at significant risk.

  • 23 to 25% of samples taken from open refillable bulk soap reservoir dispensers were contaminated with unsafe levels of bacteria
  • Coliforms, illness causing fecal-based organisms, were found in 16 to 22% of the bulk soap dispensers tested

In contrast, no contamination was found in soap that was dispensed from systems using SANITARY SEALED™ refills. Find out more >
