Universal Detection Technology to Present at the World Trade Week at the Port of Hueneme on May 25, 2005.

LOS ANGELES -- Universal Detection Technology (OTCBB:UDTT) announced today that it will be presenting its bacterial spore monitor, BSM-2000, used for detection of endospores such as anthrax, at the World Trade Week conference at the Port of Hueneme on May 25, 2005.

The conference is a joint effort by the Port of Hueneme, Pierce College International Business Center, Southern California Regional District Export Council, Oxnard World Trade Center, Oxnard College CITD, Gold Coast SBDC, The US Commercial Service, The World Affairs Council, Women in International Trade, and the LA Chamber of Commerce International Office.

The special event at the Port of Hueneme will cover topics including export controls, security and the security industry and foreign trade zones. The conference will also provide UDTT's senior management team an opportunity to meet with potential partners and experts from various agencies.

UDTT will be presenting BSM-2000 to potential partners and customers from the Port and various other agencies. "Our goal is to demonstrate the application of our endospore detection technology, developed in collaboration with JPL. We believe that ports are one of the prime targets for a bio-terrorist attack, vulnerable both as an actual target and as a hub for bringing lethal bio-agents into the homeland. Our technology can substantially increase the effectiveness of security infrastructure for ports, airports and other large public places," says Jacques Tizabi, UDTT's chairman and CEO.
