The number of E. coli O157:H7 attached
to coupons as affected by type of surface, the number in biofilm as affected
by surface type and incubation period, the number in biofilm
after treatment with a sanitizer as affected by type of sanitizer, type of
surface, and treatment time, and the number in biofilm on wooden
surfaces as affected by drying time were analyzed using Fisher's least
