It also showed a similar effect on genes associated with two other toxins &#8211; cyclopiazonic acid and aflavarin &#8211; produced by the pathogen.<\/p>\n\n\n\n<p>The continued work offers hope of an aquatic solution to a serious terrestrial problem, but the underlining mechanisms driving these genetic effects have yet to be determined. This will be explored in further work.<\/p>\n\n\n\n<p>Risks associated with aflatoxin contamination of food are high, stressed the authors of the research, noting that an estimated 4.5billion people are at risk of exposure, while 25% of global food crops are destroyed each year due to this contamination.<\/p>\n\n\n\n<p>You can read the full study in the journal <em><a
