USDA Chooses zNose to Combat Contraband Food

July 17, 2007

USDA will use the zNose from Electronic Sensor Technology to evaluate its ability to detect contraband food products in incoming international mail and at ports of entry.

NEWBURY PARK, CA--(BUSINESS WIRE)--Electronic Sensor Technology (OTCBB:ESNR), a leading manufacturer of ultra-fast vapor analyzers, announced that its zNose has been selected by U.S. Department of Agriculture (USDA) for evaluation of its suitability for use to detect contraband meat products and vegetation. Presently, the USDA randomly inspects incoming packages and mail at ports of entry for contraband food products. The zNose will enable the USDA to be more comprehensive in its inspection as well as improving the efficiency of the process.

The zNose is the first electronic nose, based on ultra-fast gas chromatography, whose results have been validated by independent laboratories, including the Environmental Protection Agency and the White House Office of National Drug Control. The zNose contains a library of retention time indices for over 700 volatile organics which enables it to easily identify specific volatile organic compounds (VOCs).

A detailed discussion (PDF) on the use of the zNose for the detection of meat can be accessed here.
