title: [Incidence of Clostridium botulinum on cattle farms].
abstract: Clostridium botulinum, mainly type B, was constantly found to be present on cattle farms. The organism was isolated both from samples of the soil of pastures and from the faeces of cattle during the winter housing period. The number of C. botulinum type B in samples of soil varied from 10 to 300 organisms per 100 grams. Contamination with C. botulinum was found to be of a similar order of magnitude on farms on which pastures are regularly dressed with sewage sludge. C. botulinum was detected in 13 per cent of the faecal samples (420 samples of one gram each). Particularly grass silage pits prepared with wilted grass were found to provide a possible link between contamination of pastures and cattle.
