a
Brushes were hanging and sponges stored openly on a tray.
b
One of the replicates below detection limit (<3.0 log per brush). Standard error not calculated.
c
Means of log cfu per brush/sponge with standard errors in parentheses.
d
11 brushes hanging, 10 brushes in plastic bag.
e
Below detection limit.
f
Number of sponges were 20 for TVC and 15 for Salmonella. For Salmonella, data from sponges below the detection limit for one or both storage conditions were removed.
