Charm Sciences is proud to announce the first Lateral Flow Quantitative test to be approved for official testing of Ochratoxin in the U.S national grain inspection system.

The ROSA® Ochratoxin Quantitative kit is the eight Charm mycotoxin test to have received approval from USDA GIPSA (Grain Inspection, Packers and Stockyards Administration). The ROSA Ochratoxin kit (Rapid One Step Assay) delivers fast, economical, accurate detection for Ochratoxin A in a convenient single strip. It has the flexibility to meet domestic and export requirements with quantitative readings and a detection range from 0 to 12 ppb (10 – 150 ppb with dilution).

Following a methanol extraction on wheat, the diluted sample is added to the ROSA OCHRA strip and read after 10 minutes. The ROSA-M reader stores Ochratoxin results electronically for record keeping and reporting. Optional mycoSOFT™ software delivers flexible and intuitive functionality with customized data trending reports.

The ROSA Ochratoxin lateral flow tests require minimal equipment and user involvement. Multiple samples can be prepared, and tested at the same time. The ROSA Ochratoxin kit uses the same extraction as the GIPSA approved quantitative ROSA methods for aflatoxin and zearalenone. The ROSA Ochratoxin kit shares the same equipment and comparable assay formats as the ROSA methods for aflatoxin, DON, fumonisin and zearalenone.

Ochratoxin is produced by some species of Aspergillus, such as A. ochraceus, mainly in tropical regions and by Penicillium verrucosum in cooler climates. Ochratoxin A is associated with porcine nephropathy and various symptoms in poultry. Ochratoxin is found in wheat, barley, corn, oats, sorghum, soybeans, coffee beans, grapes, and raisins.
