Abstract:
A sample of produce wash water containing an antimicrobial sanitizer fluid, and a reference pathogen fluid are both injected into a pathogen inactivation region of a micro-fluidic mixer. The produce wash water (i.e. sanitizer fluid/pathogen fluid mix) is directed through mixer elements in the pathogen inactivation region of the micro-fluidic mixer. In the sanitizer deactivation region, a sanitizer deactivation solution is added to the sanitizer fluid/pathogen fluid mix to produce a deactivated solution. The deactivated solution is evaluated for the presence of the pathogen and the characteristics of the sanitizer. In the preferred embodiment, the sanitizer comprises chlorine and the pathogen comprises E. coli bacteria.
