Which foods pose the highest risk of becoming contaminated?
5 Foods That Pose the Highest Food Safety Risk for ContaminationPoultry.
If not handled properly, raw and undercooked poultry (i.e.
chicken and duck) have an extremely high contamination risk.
Salmonella is also an issue with one of the biggest breakfast foods in the world.
