A preliminary study in Antioxidants reports that even low doses of purified zearalenone produced detectable multi-organ toxicity in weaned female piglets, suggesting that chronic low-level exposure to this mycotoxin may carry broader health consequences than current tolerance thresholds account for.
Zearalenone is a mycotoxin produced by several Fusarium species and is one of the most prevalent contaminants of cereal grains worldwide. It is a known endocrine disruptor with estrogenic activity, and pigs are considered the most sensitive livestock species, and a frequently cited model for human risk assessment.
The research team, led by Liu and colleagues, examined toxicity across multiple organ systems following exposure to purified zearalenone at low doses. The authors call for further investigation into chronic low-dose exposure scenarios.
