LOS ANGELES, April 23, 2008 (PRIME NEWSWIRE) -- Universal Detection Technology (OTC BB:UDTT.OB - News) (Frankfurt:PO8.F - News) (http://www.udetection.com), a developer of early warning monitoring technologies to protect people from bioterrorism and a provider of counter terrorism training and solutions, announced today that it has received a purchase order from an Israeli company for the Company's Hand Held Assays (HHA).

The Israeli government as well as private security firms are actively improving their preparedness for a bioterror attack as the potential threat of such an attack from terror organizations and states with active biological weapon programs, such as Syria, grows. As an example, large numbers of the Israeli population have received smallpox inoculations.

UDTT's anthrax detection HHAs have provided accurate results to users in the field in as little as three minutes. The assays have been purchased by first responders throughout the country as well as the U.S. Army. The kits are able to detect anthrax spores well below the threshold for an infectious dose.

``We have seen increased interest in our bioterrorism detection kits recently from Israeli security firms and we hope that this trend can open up doors to more international sales of UDTT's HHAs,'' said Mr. Jacques Tizabi, UDTT's Chief Executive Officer.
