Fusaric Acid

Printable PDF

Background Information:

Fusaric Acid is a Fusarium-produced mycotoxin, which has been shown to cause synergistic effects (increases toxicity and potential impact on livestock) in combination with Vomitoxin (DON). For example, it is now known that fusaric acid interacts with DON to cause the vomiting effects, which were previously attributed to DON alone. Fusaric Acid has also been shown to have synergistic effects with other Trichothececes (family of Fusarium toxins including DON, T2/HT2, etc.), as well as the Fumonisins and Zearalenone.

Major crops affected:

Cereal grains and their corresponding silages.

Associated mold:

Fusarium sp.

Conditions favoring production:

Wet, rainy and humid weather from flowering to harvest in corn and small grains.

Symptoms:

Inhibits growth of rumen bacteria (anti-microbial), decreased microbial protein synthesis, lowers blood pressure, anemia, lower limb swelling/lameness, lethargy, reduced feed efficiency, feed refusal, udder edema, as well as many synergistic effects like vomiting and diarrhea, among other digestive disorders.

Detection Limit:

0.1 ppm

Dairyland Packages that include Fusaric Acid:

  • Mycotoxin Basic Package
