The University of Alberta warns, with this summer's combination of abundant rain and warm temperatures, livestock producers will need to be on alert for potentially elevated levels of fusarium infection in feed grains.
Fusarium head blight is a fungal infection that primarily affects cereal crops.
Fusarium graminearum, the strain of particular concern, is present throughout Manitoba and into Eastern Saskatchewan with the Red River Valley tending to face the highest risk.

Researchers to combat toxic brown mould with its non-toxic cousin.
In the early 1960s more than 100,000 turkeys died in Britain of cancer of the liver. Eventually, researchers identified mouldy peanut flour from Brazil containing large amounts of aflatoxin as the cause of this mysterious 'turkey X' disease. Even today the toxin is regarded as one of the most virulent natural carcinogenic substances.
The tasteless toxin is produced by the mould aspergillus...

Recent hot wet weather conditions are increasing the risk of fusarium head blight developing in this year's winter wheat crops.
Fusarium graminearum, the strain of particular concern, is present throughout Manitoba and into Eastern Saskatchewan.
The toxins produced by the fungal disease are of particular concern to swine producers.
David Kaminski, a Farm Production Extension Pathologist with Manitoba Agriculture Food and Rural Initiatives, says the infection thrives under hot humid...

Grain quality is likely to have been affected by bad weather during the harvest. Pig producers are urged to be extra vigilant to ensure the quality of cereal grains going into feed is maintained so pig health, feed intake and performance do not suffer.
The wet weather has delayed harvest and also led to high grain moisture content, which increases the risk of mycotoxin development during storage.
Proper grain storage is the key. HGCA has urged growers to focus on wellestablished basics...

Autumn is a good time to find out if you have mycotoxin contamination problems in your corn, especially if it is going to be fed to swine. Mycotoxins are compounds produced in grain by specific molds or fungi as secondary metabolites. However, presence of molds in grains does not automatically indicate mycotoxin presence.
Mycotoxin production can occur during plant growth and maturity or during storage of grains, and is influenced primarily by moisture level, temperature and availability of...

Until now, scientists didn't know how to classify Stachybotrys chartarum, the black mold that can grow in humid, indoor environments and is often associated with "building sickness."
But an Agricultural Research Service scientist recently found that the toxin- producing fungus comprises a brand-new family within the order Hypocreales.
ARS mycologist Lisa A. Castlebury discovered that Stachybotrys' closest relatives are actually members of the genus Myrothecium, fungi that cause serious...
