Persistence of S. Typhimurium 14028s on lettuce and corn salad leaves. Bars display Salmonella CFU counts per g leaf fresh weight (fw) and corresponding standard deviations (n = 4) during the days after spray inoculation of the leaves. Asterisks indicate a detection of Salmonella only after enrichment. Different cell counts of Salmonella (CFU per mL) sprayed on day 0 are indicated by different shades of gray.
