A new study reveals that Roundup herbicide enhances the growth of
aflatoxin-producing fungi, lending an explanation for the alarming
increase in fungal toxins recently discovered in U.S corn, and revealing
another way in which GM farming is seriously undermining food quality.
A new study lead by Argentinean researchers and published in the Journal of Environmental Science and Health
titled, "Influence of herbicide glyphosate on growth and aflatoxin B1
production by Aspergillus section Flavi strains isolated from soil on in
vitro assay," adds to an increasing body of research indicating that glyphosate (aka Roundup),
the primary herbicide used in GM agriculture, is seriously undermining
the quality of our global food supply, and may help to explain recent
observations that GM corn heavy markets, such as the U.S., have a
significant aflatoxin problem.
Researchers from the Department of Microbiology and Immunology, National
University of Rio Cuarto, Cordoba, Argentina, set out to evaluate the
effect of glyphosate (Roundup) on the growth of aﬂatoxin B1 production
by strains of Aspergillus under different water availabilities on maize
based medium. Aflatoxin B1, one of at least 14 different types, is a
naturally occurring mycotoxin that is produced by Aspergillus flavus and
Aspergillus parasiticus, two species of fungi that commonly effect
Known to be one of the most carcinogenic substances in existence,
aflatoxin B1 is classified by the International Agency for Research on
Cancer (IARC) as "Group 1, carinogenic to humans,"
with an oral, rat LD50 (the dose that acutely kills 50% of a test
group) of 5mg/kg – compare that to a 6.4 mg/kg LD50 for potassium
cyanide, which is used in lethal injection.
