COMBAT SPREAD OF MYCOTOXINS

Search for solutions
While research regarding specific
mycotoxins and their health effects is
growing in popularity, the number of
scientists knowledgeable of the subject
remains small, Applegate said. And
research into methods of controlling or mitigating mycotoxins is lagging behind the need for them, Hogan said.
"Is identifying every single mycotoxin going
to improve the problem?" she asked. "I would say
the focus could be spent on technologies in feed
processing in particular that can eliminate poorquality grain that is associated with whole hosts of
mycotoxins, and that will improve the safety of grain
that goes into feed processing."

popularity, but the discovery of

Such technology does
exist in laboratory settings
but scaling the process to
such a size that it could
be used in a commercial
feed mill has proved challenging, Hogan said.
The bulk of the work on
mycotoxin mitigation has
focused on binding agents
and, to a lesser degree, on
enzymes that can break down
toxic compounds, Murugesan
said. These products have proved
popular for their efficacy with common
mycotoxins, especially aflatoxin, and
there are several new options about to come
on the market.

Nevertheless, producers may not realize that less
common mycotoxins - the ones that are currently
spreading - aren't so easily bound by the products available today, Applegate said.
Enzymes might be one of the best alternatives, he said,
but those require additional regulatory scrutiny to ensure
that the toxins aren't degraded into another compound
that remains toxic.

absorption is very low, they must not confer any real
effect on the animal."
More recent work, including some of his own,
suggests these toxins have a more subtle impact on
animals, making animals more susceptible to infection.
Deoxynivalenol, which is increasingly common in cooler
climates, has a similar effect.
These findings are especially concerning, Applegate
said, because the spread of mycotoxins has coincided with
increased consumer demand for antibiotic-free animal
production.
Research also increasingly points to a sort of cumulative effect among many mycotoxins when an animal is
exposed to more than one compound simultaneously. Two
combined toxins, Hogan said, may often have a greater
impact on an animal's health than either toxin would have
on its own.
In her work, Hogan said: "Any time a study is using
naturally contaminated feed rather than feed spiked with one
mycotoxin, you're bound to have more than one mycotoxin
in there. Anyone who tests their feed ... is going to find
more than one mycotoxin. And when you have a mixture
of mycotoxins, often what you will have is exacerbated or
increased effects on target tissues and
organ systems."
