Attachment strength and biofilm forming ability of Bacillus cereus on green-leafy vegetables: Cabbage and lettuce

► Bacillus cereus spores and vegetative cells adhere rapidly to green-leafy vegetables. ► Attachment strength and biofilm forming ability increase over time. ► Produce surface properties affect the attachment strength and biofilm development. ► The environmental strains are more helpful to understand biofilm formation. ► Hygienic practices must be in place to assure the safety of green-leafy vegetables.
