In response to the stop sale that the Oregon Department of Agriculture (ODA) put on Evergreen Pyrethrum Concentrate:


MGK takes the concerns stated in the pesticide advisory notice very seriously and is working with the ODA to reach an equitable conclusion. EPA has established limits for trace detectable chemicals which are determined by detailed toxicological research data. Based on criteria established in the EPA PR Notice 96-8, the bottle of undiluted Evergreen® Concentrate in question was 10,000 times below EPA-established limits for MGK-264 and 1,000 times below EPA-established limits for PBO. The trace amounts of PBO and MGK 264 that were found by the ODA were 0.067 ppm (0.0000067%) MGK-264 and 0.85 ppm (0.000085%) PBO. The Environmental Protection Agency (EPA) has set limits for both MGK-264 and PBO at 1,000 ppm (0.1%). The product remains in compliance with all EPA guidelines and Federal law. The scales of measurement of parts per million are quite small.  Some equivalencies that can help to visualize the quantities involved in ppm measurements are that 1 ppm is equal to 1 inch in 16 miles or one minute in two years.


MGK is committed to operating in an honest and ethical manner. The source of the trace amounts of PBO and MGK 264 are a result of the manufacturing process. Standard manufacturing processes such as formulating, mixing and packaging rely on equipment that is used for many different products. Care is taken to ensure residues from a production run are removed prior to beginning production of another product. All equipment, such as pipes, pumps, valves, tanks and hoses are thoroughly cleaned and rinsed between each use. MGK products are never intentionally adulterated or misbranded and any trace amounts of foreign compounds are purely incidental. MGK stands by our robust quality control and manufacturing methods. We will continue to look for ways to improve the quality of our products to meet the evolving needs and requirements of our industry.
