Universal Detection Technology Receives Purchase Order From the United States Department of Agriculture for Its Ricin

LOS ANGELES, CA, Oct 23 (MARKET WIRE) --
Universal Detection Technology (www.udetection.com) (OTCBB: UNDT)
(FRANKFURT: PO8), a developer of early-warning monitoring technologies to
protect people from bioterrorism and other infectious health threats and
provider of counter-terrorism consulting and training services, announced
today that it has received a purchase order from the United States
Department of Agriculture for its Ricin detection equipment. The USDA
plans to use the equipment to test waste seed mill from the production of
biodiesel fuels for the presence of Ricin.

The USDA provides leadership on food, agriculture, natural resources,
rural development and related issues based on sound public policy, the
best available science, and efficient management. Its responsibilities
include enhancing agricultural trade, improving farm economies and
quality of life in rural America, protecting the nation's food supply,
improve the nation's nutrition, and protecting and enhancing the nation's
natural resource base and environment. The USDA's expenditures are
estimated at $95 billion in FY 2009.

Castor oil is the best substance for producing biodiesel because it is the
only one that is soluble in alcohol, and does not require heat and the
consequent energy requirement of other vegetable oils in transforming them
into fuel. Biodiesel, chemically known as an esther, is the result of the
reaction between any oily acid with ethyl (ethanol) or methyl (methanol)
alcohol. In Europe and the United States, nearly two billion liters of
biodiesel are consumed annually.

European and U.S. farmers have created national and international
associations to promote this alternative fuel, which reduces urban air
pollution and emissions of greenhouse gases associated with the burning of
fossil fuels.

Ricin is a toxin that can be made from the waste left over from
processing castor beans. It is one of the most toxic and easily produced
plant toxins. If injected, as little as 500 micrograms of ricin could be
enough to kill an adult; some animal research indicates that similar
amounts could be lethal, if inhaled. UNDT's Ricin detection equipment has
been designed to detect trace amounts of Ricin in as little as 3 minutes.

"We are proud to announce the purchase order received from the USDA as we
strive to make our products and technology available to all sectors of
industry," said Mr. Jacques Tizabi, UNDT's Chief Executive Officer.
