Sixty soil samples were collected from the redeveloped site of the former Metropolitan (Caledonian) Cattle Market, Islington, London. Of these, 15 (25%) contained Clostridium botulinum and no less than four types (B, C, D and E) were demonstrated. Early British soil surveys suggested that only 4--8% of samples contained Cl. botulinum (type A or B). Although there can be no absolute proof, it seems likely that the striking prevalence at the Market site was the result of faecal contamination by a small proportion of the many millions of farm animals brought there from elsewhere. The distribution of Clostridium tetani was uneven, but of 18 soil samples taken from one area of the Market site, 16 (89%) were positive.
从伦敦伊斯灵顿区原大都会（喀里多尼亚）牛市的重建场地采集了60份土壤样本。其中15份（25%）含有肉毒梭菌，且至少发现了四种类型（B、C、D和E型）。早期英国土壤调查表明，只有4%-8%的样本含有肉毒梭菌（A型或B型）。尽管无法给出绝对证据，但市场场地肉毒梭菌的显著高流行率似乎是由数百万从其他地方运来的农场动物中的一小部分粪便污染造成的。破伤风梭菌的分布并不均匀，但从市场场地一个区域采集的18份土壤样本中，有16份（89%）呈阳性。
