BioLargo Signs License Agreements to Bring Next Generation Water Sanitizing System for Food Safety and Agricultural Uses to Market in the United States

LA MIRADA, CA–(Marketwire – April 6, 2010) – BioLargo, Inc. (OTCBB: BLGO) announced today that it had entered into a series of agreements to commercialize a leading water disinfection system for food safety and agricultural uses, first introduced in Australia, called the Isan system, in the United States.

Food safety is of great concern in the United States. The Centers for Disease Control and Prevention (CDC) estimates that foodborne diseases cause approximately 76 million illnesses, 325,000 hospitalizations, and 5,000 deaths in the United States each year. A recent study conducted by the Produce Safety Project at Georgetown University reported that health related costs associated with food-borne illnesses in the U.S. total $152 billion annually. Dennis P. Calvert, President & CEO of BioLargo, commented, “The Isan system is a big part of the solution to help solve food safety issues, as well as to begin replacing dangerous pesticides and chlorine based products that so often are harmful to people and our environment. We are pleased to partner with Isan USA, Inc., who has committed to bring the people and resources to take the Isan system to the United States marketplace.”

The Isan system is a patented automated water disinfection system that utilizes iodine and substantially reduces the incidence of fungal growth, spoilage organisms and pathogens in water and on food. Capable of treating high volumes of water flow, the Isan system is a combination of electrodes for measuring iodine levels in the target water stream, a control unit which automatically controls the dosage levels, iodine canisters to deliver the iodine, and resin canisters to collect by-products after disinfection has been completed. Iodine, a broad spectrum disinfectant with no known acquired resistance capabilities, is used extensively in the hospital and animal health markets due to its high level of efficacy combined with its low reactivity to human, plant and animal cells. The Isan system is registered with the APVMA (Australian Pesticides and Veterinary Medicines Authority) and FSANZ (Food Standards Australia and New Zealand) in Australia and New Zealand, where it has approximately 150 customer installations currently operating, primarily for use in horticulture, post-harvest sanitation of fruits and vegetables, dairy use, and poultry drinking water. In April 2009, the creator of the Isan system, Ioteq IP Pty. Ltd. of Australia, was chosen as one of the top 50 water companies in an international competition by The Artemis Project™.

“The Isan system is one of the most important advances in food and plant safety in the past 20 years,” said Dr. Joseph Montecalvo of California State Polytechnic University, who is a noted expert in organic post harvest handling and processing and related international standards, HACCP and EPA-FDA-USDA regulatory compliance, and food plant sanitation.

Jared Franks, President of Ioteq, added, “The Isan system holds many competitive advantages to existing chlorine based systems, and includes a major advancement in the recycling and conservation of water in post harvest food processing.” He added, “BioLargo, with its suite of complementary iodine technologies, has been instrumental in helping us develop a go-to-market path and bringing this relationship to a successful start with Isan USA. Our green technology can make a big difference in protecting people, plants, and our earth.”

Bert Fenenga, founder of Isan USA, Inc., commented, “We know this system solves many of the safety and environmental issues surrounding food processing and water treatment for a whole host of industry applications, while at the same time providing a turn-key ‘set it and forget it’ cost-effective solution that the marketplace so desperately needs, and we look forward to working through the regulatory approvals process in the United States.”

Under the series of agreements, BioLargo secured the exclusive rights to commercialize the Isan system for all fields of use, in the United States, Canada and Mexico. BioLargo will continue to market the technology on a non-exclusive basis globally. BioLargo sublicensed the rights in the United States in certain fields of use to Isan USA, Inc. The details of the agreements are set forth in the Form 8-K filed by BioLargo with the SEC on March 31, 2010.
