FDA Allows Use of Radically Different Food Safety Product For Fruit, Vegetable, Produce Industries

SelectrocideÂ? from Selective Micro Technologies Â? After Field Trials, Growers, Packers and Grocers Predict Big Savings on Products that Last Longer and Look Better on Store Shelves.

Today food safety in the United States took an important step forward after the FDA allowed the use of a radically different and highly-effective food antimicrobial called Selectrocide™ to wash fruits and vegetables. Created by Selective Micro Technologies, Selectrocide produces more than 99% pure chlorine dioxide solution. Food processors can use Selectrocide to reduce microbial levels and improve their product quality over an extended shelf life.

“It’s important for food processors to understand that bacteria and other organisms living on the surface of fruits, vegetables cause them to rot and carry disease, which may present a food safety issue” said Richard Hamilton, chief scientist and co-founder of Selective Micro Technologies. “It’s long been known that chlorine dioxide is an ideal biocide for killing unwanted organisms. However, previous products that generate chlorine dioxide have contained harmful contaminates. Selectrocide is a product that creates greater than 99% pure chlorine dioxide in a convenient, easy-to-use form. Simply add water.”

Field trials conducted by processors and grocers have shows that processed fruits and vegetables can last up to 50% longer, look and taste better by applying the Selectrocide solution. A full report of the field trial results is available at http://www.selectivemicro.com/documents/ProcFoodFieldStudy.pdf.

“The FDA’s allowance of Selectrocide on fruits and vegetables has the potential to dramatically improve food safety and quality throughout the fruit and vegetable supply chain,” said John Warner, president and co-founder of Selective Micro Technologies. “We have seen great interest from international growers planning to reduce spoilage microbes and extend shelf life of food shipped around the world.”

“The implications of Selectrocide use reach well beyond the produce industry into all segments of the food industry. Our products are cleaning clinical instruments and pharmaceutical processing equipment in addition to being used as a disinfectant and sanitizer for horticultural settings,” continued Warner. “Where there is a need to reduce microbial levels, sanitize food processing equipment, clean medical instruments, and pharmaceutical manufacturing, we plan to be there.”


Selectrocide’s use on food is particularly important for American consumers because much of the food now consumed in the United States is grown in foreign countries and shipped to grocers in North America. Food safety standards vary widely around the world and enforcement can be equally unpredictable. Bacteria and fungi found on food surfaces often manifests in growing fields and hothouses, and proliferate in transit to grocery stores in the US. Food growers who participated in Selectrocide field trials have created methods to ensure produce grown in foreign markets is sanitized prior to packaging and remains sanitized while in shipment to stores.

The field trial process yielded reduced microbial levels, increased shelf life and improved overall look and taste quality of food products.

Selective Micro’s Selectrocide is sold as sachets with reactants contained within proprietary membrane materials. The sachets are immersed into water, producing a greater than 99% pure chlorine dioxide solution, at neutral pH, with virtually no unwanted by-products. Selectrocide makes it possible to generate chlorine dioxide at specific concentrations (from 1 part per million (ppm) to 500 ppm) in specified time periods.

According to the Annual Research Report, Southwest Research Institute, San Antonio, TX, 1996, “Chlorine dioxide is a powerful biocide that can kill fungus, bacteria, and viruses at levels of 0.1 to 1 part per million in contact times of a few minutes.” The low levels of chlorine dioxide required to kill microorganisms is in stark contrast to other antimicrobials that require parts per million ranging from hundreds to hundreds of thousands of parts per million in order to be effective. Such high concentrations make the competitive products highly corrosive, dangerous to handle and difficult to rinse. Being highly effective at low concentrations means Selectrocide’s chlorine dioxide rinses off food and equipment easily, and has no adverse effect on food flavor.


Chlorine dioxide is a highly unstable gas and cannot be transported in containers or cylinders, so its potential over the last 50 years has gone untapped in many applications. For the first time ever, greater than 99% pure chlorine dioxide can easily be produced at the point of use without harmful residual chemicals, high capital expense or complex generation-plant assembly.

Formed in 1999, Selective Micro Technologies is a private company based in Beverly, Massachusetts. Combining sophisticated science with innovative product design, Selective Micro has invented a proprietary delivery system that controls the rate and efficiency of gas-producing reactions. Our competitive advantage is the ability to generate specific concentrations of chlorine dioxide with very low chemical residuals and neutral pH – at the point-of-use, using only water, without capital equipment. The Company holds two US patents, and has several other patent applications pending in the US and abroad.
