ZEARALENONE TOXICITY IN SWINE
 
Description    The molds FUSARIUM ROSEUM and F. GRAMINEARUM grow on grains, especially corn, and produce the toxin zearalenone that has estrogen-like activity. Swelling of the vulva and vagina with secondary rectal prolapse is the most common sign. High levels of zearalenone in the dam can lead to piglets being born with enlarged, edematous, and congested vulvas.
