Cross contamination occurs when a contaminated food contaminates a surface or utensil, and that surface or utensil is used again to prepare something else. The same goes for the use of hands.
This is why we don't prepare raw meat on a cutting board, plate, pan etc. and then use that same item for cooked meat or another product without washing it inbetween procedures.
Vegetables such as leaf lettuce and celery can also cause cross contamination.
The question is: How do they cause contamination?
The answer is because of bacteria in the soil.
