ROSA^®  BEST Aflatoxin P/N (Qualitative)  

The ROSA^® BEST Aflatoxin P/N Test is the first aflatoxin grain test with a water-based extraction solution.

Until now, aflatoxin detection in feed and grain has required the use of hazardous extraction solvents such as ethanol or methanol. Charm’s new BEST (Biodegradable Extraction Solution Technology) qualitative lateral flow test uses an aqueous-based, alcohol-free extraction solution that is safe for test operators and the environment.

The BEST solution is non-toxic and non-flammable, ensuring a low environmental impact and reduced storage, shipping and disposal costs compared to alcohol extractions.

ROSA^® Fast Aflatoxin Quantitative (Fast AFQ) 


Charm’s ROSA^® Fast AFQ Aflatoxin Test is the fastest USDA GIPSA approved quantitative test to measure the levels of aflatoxin in corn samples: just 3 minutes.

 ROSA Aflatoxin Quantitative - Test Procedure

ROSA^® aflatoxin P/N (Qualitative)


After sample extraction and 3 minute incubation, this test gives an accurate “Positive/Negative” result (detecting aflatoxin contamination in bulk corn samples at 20 ppb and above), with methanol or ethanol extraction. Approval

No equipment is required to read the distinct visual results. However, an optional digital reflectance strip reader has also been approved to verify results and electronically record test data. The same strip is also approved with the ROSA Reader at a 10 ppb threshold. Approval

When extracting with 70% methanol, the same diluted extract can be used to run the qualitative or quantitative strip or both. This 2-in-1 feature is unique to Charm.  It simplifies screening and confirmation and minimizes sample errors from preparing separate diluted extracts.
