Mycotoxin LC/MS QQQ Screen

Preferred Sample

Feed-grains, distillers, TMR’s, Silages, Haylages, soybean meal, and dry pet food. Submit at least 100 grams of sample (quart size bag of grain, gallon size bag of silage, forage, hay).




Days Tested


Turnaround Time

3-5 days from day of test


Mycotoxin screen by liquid chromatography- tandem mass spectrometry (LC/MS/MS). This screen is for corn, grains, silage, forage, hay, DDGs, soybean meal, dry pet food, and TMR. Mycotoxins tested: Aflatoxin B1, B2, G1 and G2, T-2 toxin, Ochratoxin A, and Sterigmatocystin at 20 ppb (0.02 ppm). Fumonisin -B1, -B2, -B3, 15-ADON, 3-ADON, DAS and DON (vomitoxin) at 200 ppb (0.2 ppm). Zearalenone at 100 ppb (0.1 ppm).

Shipping Requirements

If feed samples are wet, freeze and ship overnight to the lab on ice packs to prevent mycotoxin production in transit. If possible, ship samples at the beginning of the week to prevent production of mycotoxins over the weekend. If samples are dry ship when convenient.

Additional Instructions

Note: The lab can no longer analyze corn gluten or high protein corn concentrates (for example, Empyreal 75) for mycotoxins because of gelling of the extract during analysis that obstructs the instrument columns and can also solidify in the vials and flasks.
