FIG 1.

Average indicator bacterial counts (log CFU/g) (bars) and percentages of positive samples (lines) for different leafy greens by variety. Each variety consisted of random and targeted samples. “Other” includes bok choy, Swiss chard, kale, and beet greens. The dashed line indicates the percentage of positive samples for generic E. coli. Variety of leafy greens (spinach, lettuce, or other) was not a significant factor for any indicator bacteria. Data were log transformed prior to statistical analysis. Standard error bars shown.
