State officials say the strain of pathogenic E-coli was found in cattle fecal samples collected at one of four ranches under investigation. The ranch is within a mile of produce fields.
"This is a significant finding. It does not however close this investigation."
Kevin Reilly with the state Department of Health Services says they still don’t know how the feces could have contaminated the spinach implicated in the bacterial outbreak.
"What the connection is between cattle fecal findings and how the spinach in question was contaminated is still the next step in our investigation."
The deadly outbreak killed 3 people and sickened nearly 200.
