  • FSA/FSS – E.coli O157 super-shedding in cattle and mitigation of human risk
  • DEFRA – Interventions to reduce E.coli O157 shedding in cattle prior to slaughter
  • FSA – Trial of visual inspection of fattening pigs from non-controlled housing conditions
  • FSA - Detection of sorbitol-fermenting verocytotoxin-producing Escherichia coli O157:H-
