Salads, slurry and irrigation: survival of pathogens in soil

A study of the persistence in soil of human pathogens from cattle.

Year of Publication2009

Ready-to-eat salads may be grown in soils contaminated with human pathogens from farmyard manure or slurry. The risk of crop infection with these bacteria depends in part on their persistence in soil. This study showed that the important pathogens survived for six weeks or more but that persistence was reduced in warm, dry and sunny conditions and in peaty soils.
