Weakness, lethargy, ataxia, lateral recumbency, limb paddling, tremors, salivation, and diarrhea were observed in newborn pigs on a commercial swine farm. Many pigs became moribund and died. All had been treated with an aerosol wound spray containing 2.5% chlorpyrifos. A controlled study was undertaken to determine whether the aerosol spray was the cause of these clinical signs. Pigs exposed to aerosol spray containing 2.5% chlorpyrifos at 3 hours (n = 4) and 6 hours (n = 3) after birth developed clinical signs similar to those on the farm; none survived. Pigs exposed at 24 hours (n = 5) after birth developed clinical signs consistent with those that had developed in pigs on the farm; 3 died and 2 survived. Of 3 pigs exposed to the same spray at 36 hours after birth, 1 developed tremors 7.5 hours later and diarrhea 9 hours later, then returned to normal.
在一个商业养猪场中，新生仔猪出现了虚弱、嗜睡、共济失调、侧卧、肢体划动、震颤、流涎和腹泻等症状。许多仔猪濒死并死亡。所有仔猪都曾用含有2.5%毒死蜱的气雾剂伤口喷雾剂进行过处理。开展了一项对照研究以确定气雾剂喷雾是否是这些临床症状的病因。出生后3小时（n = 4）和6小时（n = 3）接触含有2.5%毒死蜱气雾剂喷雾的仔猪出现了与农场中仔猪相似的临床症状；无一存活。出生后24小时（n = 5）接触的仔猪出现了与农场中仔猪一致的临床症状；3头死亡，2头存活。出生后36小时接触同一喷雾剂的3头仔猪中，1头在7.5小时后出现震颤，9小时后出现腹泻，随后恢复正常。
