 APPLIED DNA SCIENCES ENTERS KOSHER FOOD AUTHENTICATION MARKET WITH HPT
                                  INTERNATIONAL


STONY BROOK, N.Y., March 23, 2007 /Business Wirel/ -- Applied DNA Sciences, Inc.
(OTC Bulletin Board: APDN - News), a DNA security solutions company, today
announced that it has entered into an agreement with HPT International, LLC
(HPT), a food authentication solutions company, under which HPT will become a
reseller of APDN's SigNature DNA Markers. HPT and Meyhen International
Corporation (Meyhen) have recently created a joint venture to provide labels for
kosher and non-kosher foods worldwide. Meyhen provides poultry processing
automation solutions to poultry markets globally. In the U.S. alone, an average
of nine billion chickens are processed annually.

Under the terms of this agreement, APDN agreed to supply its SigNature(TM) DNA
Markers to HPT to be embedded onto HPT holograms, Nylon 6 tags and
other plastic or metal food tags. HPT has been granted exclusive rights to affix
and distribute SigNature DNA Markers on such products to its customers in the
United States in the poultry and kosher food markets, and non-exclusive rights
to affix and distribute them on such products throughout the world. HPT's
exclusive rights in the U.S. poultry and kosher foods markets are dependent upon
HPT reaching specific sales goals.

We believe counterfeiting and tampering are major issues for the food industry
today and are becoming more problematic all the time. Advances in printing
technology make it easier and less expensive to mimic labels and packaging for
counterfeit branded foods. Global concerns about bioterrorism and food-based
disease transmission appear to have enhanced the consumer's appreciation for
label authenticity. In response, companies are turning to new security platforms
and intelligent labeling to provide consumers and customers a way to check for
authenticity at different points throughout the supply chain.

"We believe that our holograms and other food tags embedded with SigNature(TM)
DNA Markers will provide a significant deterrent against counterfeiting and will
allow for a forensic level of authentication," stated Israel Sar-El, CEO of HPT
International. "This will offer retailers and consumers increased confidence in
the quality and safety of the goods they are purchasing."

Dr. James A. Hayward, CEO of Applied DNA Sciences added, "This is an excellent
example of how our SigNature(TM) DNA Markers can be integrated with existing
security solutions such as holograms to provide a secure, accurate and cost
effective means to quickly and reliably authenticate and identify products. We
regard the protection of consumer health via the authentication of foods,
personal care items and pharmaceuticals as one of our highest priorities."
