Toxic Ipomeamarone accumulation in healthy parts of Sweetpotato (Ipomoea batatas L. Lam) storage roots upon infection by Rhizopus stolonifer.

Furanoterpenoid accumulation in response to microbial attack in rotting sweetpotatoes has long been linked to deaths and lung edema of cattle in the world. However, it is not known whether furanoterpenoid ipomeamarone accumulates in the healthy-looking parts of infected sweetpotato storage roots. This is critical for effective utilization as animal feed and assessment of the potential negative impact on human health.
