In Southern Rhodesia sodium pentachlorophenate (NaPCP) has been in use as a molluscicide in the control of the snail intermediate hosts of bilharziasis since 1953. Until 1959 it had been used on an experimental basis and applied under fairly strict supervision. In 1959, however, it became more easily available through commercial channels and was used as a molluscicide, sprayed on rivers and dams, by farmers using their own labourers. Fatalities occurred and a description of the signs and symptoms to be expected show that the intoxication should be easy to recognize before the condition has gone too far.It is possible with relatively simple precautions to eliminate most of the dangers and there would seem to be no reason on these grounds why NaPCP should not continue to be used on a wide scale as a molluscicide.
自1953年以来，在南罗德西亚，五氯酚钠（NaPCP）一直被用作杀螺剂，以控制血吸虫病的蜗牛中间宿主。直到1959年，它一直处于试验阶段，并在相当严格的监督下使用。然而，在1959年，它通过商业渠道更容易获得，并被用作杀螺剂，由农民使用自己的劳动力喷洒在河流和水坝上。出现了死亡事件，对预期的体征和症状的描述表明，在病情发展到严重程度之前，中毒应该很容易识别。采取相对简单的预防措施就有可能消除大部分危险，基于这些理由，似乎没有理由不让NaPCP继续广泛用作杀螺剂。
