A pilot control scheme for atrophic rhinitis was initiated in Britain by the Pig Health Control Association in January 1977. To qualify, herds must have maintained a low degree of turbinate damage and not shown clinical signs of atrophic rhinitis over a period of at least two years. Qualifying herds can import pigs only from other qualifying herds or via hysterectomy/hysterotomy methods. During the first five years, 45 herds qualified at some stage, and at the end of 1982, 34 herds (comprising about 7200 sows) were still listed. Although the scheme is not related to particular infectious agents, atrophic rhinitis has not appeared within it or in herds established entirely from listed herds, despite the fact that 31 of the 45 qualifying herds had imported stock from 15 other qualifying herds.
1977年1月，英国养猪健康控制协会启动了一项萎缩性鼻炎试点控制计划。要符合条件，猪群必须在至少两年的时间内保持较低程度的鼻甲损伤，且未表现出萎缩性鼻炎的临床症状。符合条件的猪群只能从其他符合条件的猪群进口猪，或通过子宫切除/剖腹取胎的方法进口。在最初的五年里，有45个猪群在某个阶段符合条件，到1982年底，仍有34个猪群（约7200头母猪）在名单上。尽管该计划与特定的传染源无关，但在该计划内或完全由名单上的猪群组建的猪群中，萎缩性鼻炎并未出现，尽管45个符合条件的猪群中有31个从其他15个符合条件的猪群进口了种猪。
