In May 2019, 96 cattle died from Pimelea toxicity in a period of 19 days after potential exposure, with the first deaths occurring within 5 days. After examining the circumstances, we suspect that several factors contributed to the deaths. These included that recently purchased stock and transported had access to flooded land containing Pimelea elongata. This weed species contains simplexin and 18 other compounds. Roots, flowers and seeds are significantly more toxic than the stem, branches and leaves. We suspect that thirsty and hungry stock consumed seed and roots from flooded pastures and consumed lethal doses of simplexin. Blood tests were not good indicators of the conditions. Management strategies are suggested.
2019年5月，96头牛在可能接触到有毒植物后19天内死于瑞香科植物中毒，首次死亡发生在5天内。在调查了相关情况后，我们怀疑有几个因素导致了这些牛的死亡。其中包括最近购买并运输来的牲畜能够接触到被水淹没的、生长有长叶瑞香的土地。这种杂草含有单辛毒素和其他18种化合物。其根、花和种子的毒性明显高于茎、枝和叶。我们怀疑口渴饥饿的牲畜食用了被水淹没牧场中的种子和根，从而摄入了致命剂量的单辛毒素。血液检测并不是这些状况的良好指标。文中还提出了管理策略。
