The US Department of Agriculture (USDA)-GIPSA (Grain Inspection, Packers & Stockyards Administration) backed the two-minute assay.
Charm’s ROSA DONQ2 Quantitative Test uses the Charm Rapid One Step Assay (ROSA) lateral flow technology to quantitate DON in the assay that uses water as the extraction solvent.
“Charm’s DONQ2 test meets the extended test range criteria established by USDA-GIPSA for the rapid detection of DON in feed and grain,” said Mark Tess, mycotoxin product manager at Charm Sciences.
The test is approved for barley, brown rice, buckwheat, corn, corn bran, corn germ meal, corn gluten feed, corn gluten meal, distillers dried grain with solubles, hominy, malted barley, milled rice, oats, rice bran, rough rice, rye, sorghum, soybean meal, triticale, wheat and wheat bran.
It is approved on the Charm EZ-M system. The all-in-one system identifies the appropriate mycotoxin test using colour-coded strips then reads and displays the quantitative test results; test data is stored on an SD card for reporting and analysis.
Charm manufactures ROSA tests to detect mycotoxins (aflatoxin, DON/vomitoxin, fumonisin, ochratoxin, T2/HT2, and zearalenone) in feed and grain.
In September, Charm was visited by Dr James Sasanya of the FAO/IAEA division of nuclear techniques in food and agriculture in Vienna, Austria.
IAEA has worked with Charm to put the Charm II system in government and university labs worldwide.
The Charm II test can detect a range of residues in meat tissues, dairy, animal urine, farmed fish, farmed shrimp, water, eggs, feed and honey.
