Quaternary ammonium compounds are molecules which contain a nitrogen atom with four other atoms bonded to it. Most quaternary ammonium compounds are organic compounds and have biological activity. These compounds often work well as disinfectants, offering bactericidal and bacteriostatic effects.
D/E Neutralizing Broth, as the transport media in this unit, has the ability to neutralize a broad spectrum of antiseptic and disinfectant chemicals including quaternary ammonium compounds, phenolics, iodine, chlorine preparations, mercurials, formaldehyde and glutaraldehyde (see Chart 1 ). It is intended to facilitate survival of organisms in the sample during transport to the lab.

Specimen Collection (1)
Aseptically collect sample. Collect sample by rubbing the swab over the sample area (approximately 50cm 2 ), reversing directions between strokes. Repeat the collection procedure three more times, returning the swab head to the D/E Neutralizing Broth after swabbing each area. When sampling utensils such as knives or ladles, run the swab over the entire surface of the instrument three times, as described above. If sample is not immediately taken to the lab the sample can be refrigerated for up to 24 hours prior to analysis.
