Escherichia coli O157:H7 in Feral Swine Near Spinach Fields and Cattle, Central California Coast. Emerging Infectious Diseases. 13:12.

Interpretive Summary: The pathogen E. coli O157:H7 has been shown to infect produce. E. coli O157:H7 was isolated from agricultural environments, including ferel swine, cattle, water, sediment and soil during a nationwide outbreak investigation, associated with spinach in 2007.

Technical Abstract: We investigated involvement of feral swine in contamination of agriculture fields and surface waterways with Escherichia coli O157:H7 after a nationwide outbreak traced to bagged spinach from California. Isolates from feral swine, cattle, surface water, sediment, and soil at 1 ranch were matched to the outbreak strain.
