The Company reported a third-quarter loss before taxes of ($876,370), or ($0.03) per share, compared with a loss of ($871,452), or ($0.04) per share, in the third quarter of the previous year.

Revenues for the nine-month period were $328,842, an increase of 107%, as compared with revenues of $158,925 in the nine-month period of the prior year.  The Company reported a loss before taxes for the nine months ended April 30, 2007 of ($2,751,772) or ($0.11) per share, as compared with a loss of ($2,400,142), or ($0.13) per share, in the nine months ended April 30, 2006.

Michael L. Krall, President and CEO, said, “The third quarter was one filled with important milestones for PURE.  We started off the quarter with the excellent report from the Tulsa County Jail that the use of Staph Attack® hard surface disinfectant containing PURE’s patented silver dihydrogen citrate (SDC) had eradicated the long-standing Staph infection problem at the jail.  Formerly, the jail was reporting an average of 12 cases each month of the resistant form of Staph known as Methicillin Resistant Staphylococcus Aureus (MRSA).  In the 10 months since using Staph Attack, the jail reports no new cases of Staph.

“Also during the quarter, we announced the first filing with the FDA for an SDC-based hand sanitizer formulation by our pharmaceutical research and development partner, Therapeutics, Inc.  Since the IND filing for hand sanitizer,Therapeutics has identified lead product formulations for testing, finalized a study protocol and is preparing to initiate the first human clinical trial under this IND which is expected to begin by the end of this month."

Continued Krall, “We continue to aggressively broaden the commercialization of SDC-based products.  In March, Lifebio/PCI was licensed to actively market and sell non-pharmaceutical SDC-based antimicrobial products in Brazil for use in institutional, industrial, agricultural and food processing products, for which they are currently obtaining necessary local regulatory approvals.  We anticipate the first orders for concentrate from our Brazilian distributors will commence by the end of the calendar year.

“Interest from new licensing partners continues to grow. We have several new agreements for distribution of our SDC-based hard surface disinfectant in process and look forward to signing them in the coming weeks.

“Projects being pursued by some of our distributors include opportunities in the travel and hospitality markets. We are conducting additional formulation development and laboratory testing in order to enter these markets with a disinfectant that can be diluted on-site and provides residual viral protection.  In addition, we continue our discussions with international and domestic companies for integration of SDC into third-party household/consumer product lines.

“Consistent with our growth strategy, last month we announced the completion of a 20-fold capacity expansion of our SDC production facility – increasing our annual SDC revenue capacity from $11 million to more than $250 million.  We also added a new automated blending and packaging operation to provide a cost-effective, quick turn around alternative for smaller distributors. In the current fiscal quarter, we look forward to our GMP suite becoming certified, which is a requirement for us to be able to manufacture SDC as an active pharmaceutical ingredient,” concluded Krall.
