Zearalenone is a potent non-steroidal estrogenic metabolite produced by several fungal genera, specifically Gibberella and Fusarium. Some of the more common adverse effects from zearalenone include breeding problems and infertility in farm animals, with female swine being the most susceptible to these estrogenic effects. Zearalenone is frequently found in cereal crops, including maize, barley, oats, wheat, rice, and sorghum. Due to the wide range of commodities zearalenone can be detected in, analytical methods such as ELISA is a useful means to provide rapid screening and identification of samples containing high levels of zearalenone. The Hygiena™ Helica™ Zearalenone Low Matrix ELISA is a competitive enzyme-linked immunoassay intended for the quantitative detection of zearalenone in cereal crops, such as maize, barley, oats, wheat, rice, bread, and animal feeds.
