The authors describe the case of a 27-year-old man who was examined on account of vertigo and blurred vision. In the objective case-history there was mild confusion, in the physical examination broad symmetrical mydriasis dominated. Later other similar patients were found. Atropine intoxication was proved. The source of the alkaloid was poppy seed contaminated with seeds of henbane (Hyoscyamus niger), in bakery goods served in the works canteen.
