Tissue samples from 27 casualty adult dairy cattle slaughtered on farms and 32 ‘normal’ cull dairy cattle were analysed microbiologically for total viable counts (tvc), Enterobacteriaceae, Escherichia coli o157, Salmonella enterica and Campylobacter species. Overall the counts of Enterobacteriaceae and tvc were higher in the animals slaughtered on farms, particularly in the spleen. One ‘normal’ animal yielded E coli O157, and one yielded Campylobacter jejuni, and eight of the cattle slaughtered on farms yielded C jejuni and five yielded S enterica.
