A method for the isolation of listeria which enabled a more rapid detection of the organism was used to examine samples of silage and bird faeces. Faecal samples indicated that seagulls feeding at sewage works had a higher rate of carriage than those elsewhere. Faecal samples from rooks generally suggested a low incidence of listeria except on one occasion when eight of twenty samples contained Listeria monocytogenes: this coincided with the nesting season and the peak period for listeriosis in sheep. The incidence of L. monocytogenes in clamp silages ranged from 2.5-5.9%, but in samples of big bale silages the incidence was 22.2% and, when mouldy samples were selected, 44%.
一种用于分离李斯特菌的方法能够更快速地检测到该微生物，此方法被用于检测青贮饲料和鸟类粪便样本。粪便样本表明，在污水处理厂觅食的海鸥携带该病菌的比例高于其他地方的海鸥。总体而言，白嘴鸦的粪便样本显示李斯特菌的感染率较低，但有一次，20份样本中有8份含有单核细胞增生李斯特菌：这与筑巢季节以及绵羊李斯特菌病的高峰期相吻合。窖贮青贮饲料中单核细胞增生李斯特菌的感染率在2.5%至5.9%之间，但在大圆捆青贮饲料样本中，感染率为22.2%，若选取发霉样本，感染率则为44%。
