OC Outbreak not linked to Salinas

The latest from Orange County indicates the E. coli strain that has caused multiple illnesses for patrons of a Souplantation restaurant has not been found in California before and not associated with the Salinas spinach outbreak.
From the LA Times:

Sutter said health officials have not identified the source of the E. coli outbreak. The strain of the bacteria is rare — but not necessarily deadlier — and has not been reported in California, he said. It is different from the strain linked to the spinach grown near Salinas, Calif., that was identified as the cause of an E. coli outbreak last summer that killed three people, including a toddler.
