Serious outbreaks of a paralytic disease in cattle occurring in the spring and summer of 1988 were investigated on three farms in south eastern Queensland, Australia. On one farm 237 (31 per cent) of 770 cattle died, on the second 109 (40 per cent) of 271 cattle died and on the third 30 (8 per cent) of 380 cows died. Botulism was suspected on the basis of the clinical signs, the lack of significant pathology, a failure to incriminate other agents and a positive feeding trial in one sheep. Laboratory tests for the presence of botulinum toxin failed to confirm this diagnosis, and further feeding trials using ingredients of two rations were also negative.
1988年春夏时节，澳大利亚昆士兰州东南部的三个农场发生了牛群严重的麻痹性疾病疫情。在一个农场，770头牛中有237头（31%）死亡；在第二个农场，271头牛中有109头（40%）死亡；在第三个农场，380头奶牛中有30头（8%）死亡。基于临床症状、缺乏显著病变、未发现其他致病因素以及对一只绵羊进行的阳性饲养试验，怀疑是肉毒中毒。检测肉毒杆菌毒素的实验室检测未能证实这一诊断，使用两种日粮成分进行的进一步饲养试验结果也为阴性。
