SANTA ANA, CA - (NewMediaWire) - May 31, 2016 - BioLargo, Inc. (OTCQB: BLGO) announced today that its licensee, Clarion Water, had received approval from the United States Environmental Protection Agency (EPA) for its aqueous iodine product, IoMax™, for sanitation of poultry drinking water. IoMax™ is supplied through the patented iSAN™ delivery system that accurately doses aqueous iodine into water systems. The iSAN system is licensed by Clarion from BioLargo and its joint venture partner Peter Holdings Ltd. of Australia.

"Effective and measurable control of pathogens in poultry operations is a priority for growers looking to protect their animals, especially in antibiotic-free lines," said Tom Bercaw, President of Clarion Water. "Use of an iSAN system to deliver metered IoMax provides effective sanitation with full automation, data logging and remote monitoring capabilities."

The active ingredient of IoMax™, free iodine, is well known for its efficacy as a broad-spectrum biocide across a wide variety of industries and applications. The iSAN system has the flexibility to deliver IoMax™ to provide beneficial supplementation to the animal diet with low levels of residual iodine when desired.

Clarion reports that state registrations for IoMax are still pending and it plans on pursuing additional approved uses in the near future.

Dennis Calvert, president of BioLargo, commented, "EPA approval for our iSAN related technology is a big step for our licensee and for BioLargo towards successful commercialization. It goes hand-in-hand with our efforts underway in Canada, where we plan for commercial trials with poultry processers, co-sponsored by the Alberta Poultry Growers Association, once the commercial prototype of our AOS Filter is finished. With the iSAN system, our AOS Filter, our award winning animal bedding products, and CupriDyne® Clean, we are building a complete suite of best-of-class products to make the production of poultry foods clean, safe and healthy. This is a great example of our commitment to 'Make Life Better' and it is an important milestone in our journey."
