"Differences of opinion exist regarding the role of molds and mycotoxins in livestock problems basically because their effects on animal health and production are still in a grey area". (Seglar & Mahanna, 1995). "Mycotoxins can have a very pervasive, yet subclinical effect on both performance and health in ruminants that can easily go unnoticed. If you wait until clinical symptoms of mycotoxin problems are obvious, you no doubt waited too long". (Eng,...

Poor storage continues to be potentially a weak link for quality in the cereal supply chain. However a new £1.3 million LINK project, funded jointly by Defra and industry, is aiming to find solutions to current storage challenges. Facing up to storage difficulties and finding solutions is Link project’s goal Results from a survey conducted in 2006 by English Food and Farming Partnership (EFFP) revealed that almost one-quarter of farmers surveyed felt their...

DON mycotoxin contamination of grain is likely to be low this year, although toxin levels could be higher where wheat has lodged early and if bad weather delays harvest. Over 90 per cent of the 300 samples collected under the national winter wheat survey show symptoms of fusarium head blight (FHB), caused predominantly by microdochium species, which are non-toxin producers. Fusarium poae, fusarium culmorum and fusarium graminearum, which produce the mycotoxin deoxynivalenol...

Mycotoxins are secondary metabolites secreted by various moulds such as Aspergillus, Penicillium and Fusarium. They are synthesised during the production, transport and storage of food supplies in certain environmental conditions. Detectable levels of nearly 300 potentially toxic metabolites secreted by moulds contaminate 25 to 40% of the cereals and cereal products worldwide (Pittet, 1998; Yiannikouris and Jouany, 2002). Despite recent food crises (e.g., bovine spongiform...

Feed is the most versatile variable in animal production, yet it is one of the most vulnerable to contamination. In the battle against mycotoxin-induced productivity losses, the feed really is the variable. In his 1984 paper, ‘Determining safe levels for mycotoxins’, P.B. Hamilton, Professor of Poultry Science at North Carolina State University concluded that ‘there are no safe levels for mycotoxins.’ The fact that he continued to...

HGCA has published new guidelines to minimise the risk of mycotoxins in cereals.
“The guidelines are designed to help growers identity the risk factors and the appropriate agronomy which can minimise risk of mycotoxins from field infections,” said Dr Roger Williams, HGCA’s assistant research director.
In July 2006 new legal limits were introduced for mycotoxins produced by various Fusarium species, which can cause ear blight. The legal limits apply to grain intended for human...

Mycotoxins are a group of secondary fungal metabolites exhibiting a wide range of chemical structures. These toxins lead to a variety of toxicities in various target organs in animals and humans. The toxic effects of mycotoxins can be divided into those requiring metabolic activation in the exposed individuals, and those which do not, although the overall pathological responses to some mycotoxins have their origin in both categories. The fate of a mycotoxin in the animal body depends...

Global animal health company Alltech will host a Mycotoxin Awareness meeting on November 14 in Middlebury, Indiana. Local dairy producers will have the opportunity to learn more about toxic metabolites found in stored grain, forage, silage and even in pasture grasses.
The focus of the meeting is to bring together dairy producers to discuss solutions to mycotoxin contamination. Dr. Simon Timmermans will discuss ways to recognize the effects of mycotoxin contamination in the feed, as well as...

The most commonly recognized feed-borne mycotoxins are the aflatoxinsand the Fusarium mycotoxins. Our understanding of the etiology ofaflatoxicosis is far more complete than our corresponding understanding ofFusarium mycotoxicoses. This is perhaps because of the large volume ofliterature fueled by the acutely carcinogenic nature of aflatoxins. Analyticalmethodology for aflatoxins in feedstuffs is also simple, sensitive andreproducible. This is due, in part, to the natural fluorescence of...

It has become common in our hurried world for many people to accept the philosophy “Don’t sweat the small things!” as their solution for many of life’s little
inconveniences. While this may be true when it comes to things like parking
tickets and missed phone calls the philosophy is not applicable when it comes
to livestock production and feed quality. If you are a swine or poultry producer
one small thing can prove devastating and turn a profitable operation into
a financial...

Mycotoxins are secondary metabolites produced by filamentous fungi that cause a toxic response (mycotoxicosis) when ingested by higher animals. Fusarium, Aspergillus, and Penicillium are the most abundant moulds that produce these toxins and contaminate human foods and animal feeds through fungal growth prior to and during harvest...

Generals: Deoxynivalenol is a mycotoxin produced by fungi of the Fusarium genus, i.e. Fusarium culmorum and Fusarium graminearum , which are abundant in various cereal crops (wheat, maize, barley, oats, and rye) and processed grains (malt, beer and bread). Chemically it belongs to trichothecenes. In contaminated cereals 3- and 15-acetyl DON can occur in significant amounts (10 – 20%) concomitantly with DON. The fungi producing...
