Fig. 1 — Populations (log CFU/cm²) of seven S. enterica strains on Romaine lettuce leaf tissue immediately after inoculation (Day 0) and after 1 (Day 1) and 2 days (Day 2) incubation at 8 ± 1 °C. Treatments: : untreated tissue (controls); : 1.0 mM CaCl₂ solution applied 24 h before inoculation; : 1.0 mM CaCl₂ + five-bacteriophage cocktail applied 24 h before inoculation. (A) S. Enteritidis S3. (B) S. Javiana S200. (C) S. Javiana S203. (D) S. Newport S195. (E) S. Newport S2. (F) S. Thompson S193. (G) S. Thompson S194. Different superscripts (a–d) denote significant differences (P < 0.05) between treatments on Day 0 between strains. Different superscripts (A–F) denote significant differences (P < 0.05) between treatments on Day 1 between strains. Different superscripts (a–e) denote significant differences (P < 0.05) between treatments on Day 2 between strains. Means and standard deviations were calculated using data from five biological replicates. Limit of detection is > 0.36 log CFU/cm².
