Development of a Robust Method for Isolation of Shiga Toxin-Positive Escherichia coli (STEC) from Fecal, Plant, Soil and Water Samples from a Leafy Greens Production Region in California
Figure 4
Incidence of O157 and non-O157 STEC in samples processed by M1, M2 and M3.
Samples were processed over a 2.5 year period by M1 (IMS and NT-RA for O157 only+plating enrichment with Ct <26 for stx on C-O157), M2 (M1+ picking suspect STEC from NT-RA), M3 (M2+ mSBA).
