Mycotoxin Survey: May 2019 Update

BIOMIN offers its latest report on mycotoxin prevalence across the U.S.

During the month of April, BIOMIN received an additional 48 samples of feeds and feedstuffs from 31 states to add to its PROcheck® mycotoxin survey.

A grand total of 620 samples have now been analyzed and complied into this Mycotoxin Update Report for May 2019.

Take a look at the top-line trends below for each feed ingredient, andclick hereto see the full report on mycotoxin prevalence across the U.S.

Corn

• 98% of ground corn samples are positive for at least one mycotoxin, vs 89% in 2017
• 72% of samples have more than one mycotoxin, vs 47% in 2017
• 黄曲霉毒素患病率在干燥的玉米increased to 9% vs 4% in 2017, with average contamination levels increasing over four fold.
• Deoxynivalenol (vomitoxin) prevalence rose to 77% vs 70% in 2017, with average contamination level increasing by 44%
• Fumonisin prevalence jumped to 78% vs 52% in 2017, with average contamination levels increasing by 42%
• Zearalenone prevalence increased to 44% vs 25% in 2017, with average contamination levels remaining steady.

Corn By-Product

• 96% of samples are positive for at least one mycotoxin, vs 100% in 2017.
• 90% of samples have more than one mycotoxin, vs 94% in 2017.
• Aflatoxin prevalence decreased to 1% vs. 9% in 2017, both years with similar and low contamination levels.
• Deoxynivalenol (vomitoxin) prevalence decreased slightly to 94% vs 99% in 2017, with average contamination level increasing by 46%
• Fumonisin prevalence is 88% vs 91% in 2017, with average contamination levels remaining steady.
• Zearalenone prevalence is 84% vs 80% in 2017, with average contamination level nearly 2.7 fold.

Corn Silage

• 93% of samples are positive for at least one mycotoxin, vs 91% in 2017
• 65% of samples have more than one mycotoxin, vs 30% in 2017, a drastic increase in co-contamination.
• Aflatoxin prevalence is 1% with low average contamination levels.
• Deoxynivalenol (vomitoxin) prevalence has increased slightly to 90% vs. 85% in 2017, with average contamination level nearly doubling.
• Fumonisin prevalence increased to 36% vs 12% in 2017, with average contamination levels increasing by 10%
• Zearalenone prevalence jumped to 60% vs 26% in 2017, with average contamination level increasing over two fold.

These contamination levels present MEDIUM to HIGH risk for all livestock and poultry species depending on toxin and feed ingredient type.

Overall, producers in the Midwest should be on the lookout for the impacts from deoxynivalenol and zearalenone, while Southern states should be vigilant regarding fumonisin and aflatoxin contamination.
