Chemical type: 

Hydroxyfuropyranone

Toxicity: 

The oral LD50 in rats and mice is 30-35 mg/kg body-weight causing liver, spleen and kidney damage with oedema and haemorrhaging. It has been suspected as carcinogenic for many years and recent assessments of chronic toxicity have not conclusively removed this possibility.
