Neogen Corporation has developed an improved line of mycotoxin tests that use water as the solvent in the extraction process.

Reveal Q+ MAX for Aflatoxin is the first test in the line, and it can deliver results ranging from 2 to 300 parts per billion (ppb) of aflatoxin after six minutes.

The tests have 25 per kit and allow testing for up to six mycotoxins from the same prepared sample.

It detects the four principle types of aflatoxin, B1, B2, G1 and G2, with superior cross-reactivity when compared to other tests, claims the firm.

For B1 it is 100%, B2 it is 91%, G1 is 87% and G2 64%, according to Neogen.

Onsite and quantitative results

Water-based extraction eliminates methanol and ethanol from the process.

The test kits use the AccuScan line of readers providing customers with documentation of testing, tracking and trending capabilities.

Aflatoxin is a known severe threat to human and animal health and more than 100 countries have established regulatory limits in commodities intended as human food or animal feed. The toxin is a by-product of mold growth in a range of commodities, including corn.

Neogen launched a quantitative microwell test for total aflatoxin that used a water-based solution for extraction last year.

Veratox for Total Aflatoxin delivers results from 5 to 300 ppb after 10 minutes.

Neogen told us that Reveal Q+ MAX would complement existing lines, offering customers a choice in testing formats for mycotoxin testing whether they prefer ELISA assays or lateral flow.

Ed Bradley, Neogen's vice president for food safety, said: "This innovative technology yields more accurate and reproducible results than competitive tests on the market. Coupled with AccuScan readers, the Reveal Q+ MAX system objectively reads, analyzes and stores test results.

"Our test for aflatoxin is the first in our new line of fully quantitative lateral flow tests for mycotoxins that replace ethanol with a common water-based extraction — without compromising accuracy.”

More products to follow

Bradley said tests for DON, ochratoxin and zearalenone are in the final stages of development.

“The ability to test the same sample for up to six mycotoxins represents a potentially significant cost and time savings for grain testers.

“Until now, testers had no choice but to prepare separate samples for each mycotoxin to be tested for — by far the largest time-consuming element of the entire testing process. Our Reveal Q+ MAX products will eliminate the need for that duplication.”

Neogen’s line of mycotoxin test kits detect aflatoxin, aflatoxin M1, deoxynivalenol (DON), fumonisin, ochratoxin, T-2/HT-2, and zearalenone.
