Ninety-eight samples of pig slurry from 54 farms were examined for the presence of salmonellas, porcine enteropathogenic strains of haemolytic Escherichia coli and mycobacteria. Salmonellas were isolated from 12 farms (22 %) and enteropathogenic E. coli from 13 farms (24%). Pathogenic mycobacteria were not isolated.

Salmonellas were isolated from 7 of 16 farms (44%) stocked with ‘minimal disease’ pigs compared with only 5 of 38 farms (13%) stocked with conventionally reared pigs. Conversely enteropathogenic coliforms were isolated from 3 of 16 farms (19%) stocked with ‘minimal disease’ pigs compared with 10 of 38 farms (26%) stocked with conventionally reared pigs.
