Charm Sciences announced the company was awarded a five year contract to use the ROSA DONQ2 Quantitative Test to monitor vomitoxin (DON) in feed and grains, from The United States Department of Agriculture’s Federal Grain Inspection Service (USDA-FGIS)
- USDA-FGIS will use the DONQ2 test for official vomitoxin (DON) testing
- USDA-FGIS used Charm to test for vomitoxin over the last five years as well, first with Charm’s ROSA FAST5 DON test, then with the DONQ2 test.

Mark Tess, Ph.D., Mycotoxin Product Manager at Charm Sciences said, “Charm is excited to be awarded the DON contract for another five years to test grains in the FGIS’s testing program.” “The DONQ2 test is FGIS approved for 21 commodities and the 2-minute incubation time allows for rapid measurement to meet the demands of the program.”
The DONQ2 test utilizes Charm’s patented Rapid One Step Assay (ROSA) technology to quantitate DON in just two minutes. And its easy-to-run the test using water as the extraction solvent.
The DONQ2 test can be read and recorded using the all-in-one Charm EZ-M System.
