Table 3.

Water activity (a_w)^a of Romaine lettuce and cantaloupe tissues after 0, 1 and 2 days of incubation at 8 ± 1 °C.

Time (days)	Romaine Lettuce^b	Cantaloupe^c
0	0.845 ± 0.027^a	0.983 ± 0.002^B
1	0.494 ± 0.022^b	0.993 ± 0.006^A
2	0.492 ± 0.022^b	0.977 ± 0.002^B

Means and standard deviations were calculated using data from n = 3 to 5 replicates. Lettuce leaf and cantaloupe flesh sections (2 × 2 cm) were sampled at time points corresponding to day 0, 1 and 2 post inoculation.

Different letters (a to b) in the lettuce column indicate significant differences (P < 0.05) among water activity from lettuce leaf sections on day 0, 1 and 2.

Different letters (A to B) in the cantaloupe column indicate significant differences (P < 0.05) among water activities from cantaloupe leaf sections on day 0, 1 and 2.
