OUTBREAK SUMMARY:
This 2005 McGrath's Fish House outbreak of E. coli O157:H7 infections was traced back to parsley from Cal-Farms. The journey to finding the source was interesting: 206 people interviewed, 64 ill people, extremely muddy field conditions, cattle near the flooded parsley fields, and even evidence of heavy deer presence.
