Ricin Found in U.S. Capitol's Off-Site Mail Facility

LOS ANGELES, CA -- (Marketwired) -- 04/17/13 -- Universal Detection Technology (www.udetection.com) (OTCQB: UNDT), a developer of early-warning monitoring technologies that protect against biological, chemical, and radiological threats, reported today on the discovery of Ricin in the U.S. Capitol's off-site mail facility. The Company is a supplier of Ricin detection kits and has previously supplied the Washington D.C. Fire and Emergency Medical Services with its biological weapon detection kits that can detect Ricin in 3 minutes.

According to law enforcement sources, the letter was addressed to the office of Sen. Roger Wicker, R-Mississippi. After the envelope tested positive in a first routine test, it was retested two more times, each time coming up positive.

Ricin is a highly toxic substance derived from castor beans. As little as 500 micrograms, an amount the size of the head of a pin, can kill an adult. There is no specific test for exposure and no antidote was exposed.

UNDT's biological detection equipment has been extensively used by first responders and private industry throughout the country. The equipment has been evaluated by the U.S. DOD as well as the United Kingdom military. The equipment's capacities include:

• No cross-reactivity to household powders
• No set up time
• No expensive reader needed
• No decontamination requirements
• No false positives
• No false negatives
• No hook effect

"First Responders are much better equipped today in detecting biological weapons then they were in 2001 during the anthrax mailings," said Mr. Jacques Tizabi, UNDT's Chairman and CEO. "We are proud to have previously supplied first responders in our nation's capital with our equipment and will continue our development of detection technologies," he added.
