In late July of 1994 two 11-mo-old Holstein heifers were found dead inside a barn after a break-and-entry into it by several animals. The other animals showed no signs of sickness. The predominant postmortem findings were pulmonary edema and muscular hemorrhage. Chemical analysis found endosulfan, dieldrin, DDT and DDE in the rumen contents of both animals. The owner admitted that a very old bottle of pesticide had been knocked over and consumed by these animals; the lid consisted of plastic tape. The sale of DDT to the public was discontinued in the US on January 1, 1973, and the sale of dieldrin was halted in the US in 1987. This case demonstrates that poisoning by long obsolete farm chemicals still must be considered in differential diagnoses of acute deaths.
1994年7月下旬，两头11月龄的荷斯坦小母牛在 barn 内被几只动物闯入后被发现死亡。其他动物没有生病迹象。主要的尸检结果是肺水肿和肌肉出血。化学分析在两只动物的瘤胃内容物中发现了硫丹、狄氏剂、滴滴涕和滴滴伊。主人承认，一瓶非常旧的农药被这些动物打翻并食用了；瓶盖是用塑料胶带封住的。1973年1月1日美国停止向公众销售滴滴涕，1987年美国停止销售狄氏剂。该病例表明，在急性死亡的鉴别诊断中仍必须考虑长期过时的农用化学品中毒情况。
