Elevated DON risks a problem for pig farms

Thanks to a period of wet and snowy weather parts of the U.S. and Canada, experts are advising operations that handle corn or feed ingredients to be cautious of mycotoxins going forward.

Of particular concern is deoxynivalenol, or DON. This mycotoxin is produced by a mold that flourishes in wet conditions and is a major […]

Up in the air — Drones aid in fight against mycotoxins

The appearance of mycotoxins in a field of crops isn’t usually an isolated instance. The toxins, which are produced by fungal growth on plants, can have a widespread presence in any given growing season. When one region suffers through a bad episode with a mycotoxin, nearby areas tend to struggle as well.

That’s why farmers […]

Mycotoxins 101, part 1: What are they, and how do we test for them?

The discovery of the mycotoxin aflatoxin in the 1960s led to a boom in scientific and regulatory interest in mycotoxins. When it was found that aflatoxins can be carcinogenic in animals, an urgent need was sparked to facilitate a greater regulation of mycotoxins in food commodities.

But what are mycotoxins?

“Mycotoxins are the toxins produced […]

DON outbreak highlights storage concerns for grain

DON: it’s nasty, it’s dangerous and it’s being currently found in high levels in stored grain around the Corn Belt region of the United States.

DON — a.k.a., vomitoxin — is a mycotoxin created by Fusarium molds, especially F. graminearum. When consumed, it can cause nausea, vomiting (hence the nickname), gastroenteritis, diarrhea, immunosuppression and even […]

Storage of Midwest corn causing mycotoxin concerns

2016 brought a bumper corn harvest thanks to favorable weather conditions throughout the U.S. that resulted in a record amount of corn available for export. However, with the good also comes the bad. Because such a large amount of corn was produced, a large amount also had to be stored — typically in outside piles […]

Study shows danger of mycotoxins for horses

It is well known that contaminated feed can cause serious problems for horses, ranging from colic and cardiac problems to neurologic issues and death. Mycotoxins can be a main component of these health problems which was recently documented a case in which feed contaminated with trichothecene mycotoxins caused bone marrow cell proliferation suppression, severe bleeding, […]

Report: U.S. winter wheat worst quality in 17 years

The quality of some of the first wheat harvested by U.S. farmers in 2015 is the worst in at least 17 years, according to one measure and following heavy rainfall across parts of the Midwest.

A report released last week by U.S. Wheat Associates tracked the “falling number,” a gauge of sprout damage in crops […]

Wet weather brings wheat harvest issues to forefront

Mother Nature has not been very kind to several areas of the U.S., where wheat farmers in particular are continuing to deal with Fusarium head blight (FHB), caused by a fungus known as Fusarium graminearum, which attacks grain directly and is a result of wet weather conditions during the growing season.

FHB is a problem […]

Wheat harvest continues as do mycotoxin concerns

While warmer, drier weather has allowed the hard red winter wheat harvest to gain considerable momentum after a slow start, concerns about the soft red winter wheat crop have been mounting as moisture takes a tool on both harvest progress and milling quality.

According to a recent article, although the soft red winter harvest did […]

Dealing with scabby wheat? Answers to your questions here

This year, some North Carolina fields may experience high levels of Fusarium head blight (FHB or scab) from wet weather conditions during the flowering and grain filling stages of plant development. Scab causes low yields and test weights and can cause grain to be docked or rejected because of mycotoxins, especially deoxynivalenol, also known as […]
