Feather plucking

Feather plucking of chickens is done by means of discs containing rubber or plastic plucking-fingers. These discs turn around in opposite directions, which helps to keep the carcasses in upright position, which facilitates feather removal. Water is spread upon the carcasses continuously to improve the plucking effect. Disposal of the loose feathers is important in order to minimize cross contamination.

During plucking physical forces may press fecal material from the cloaca, which can contaminate both the equipment and other carcasses. The richt adjustment of the plucker may not be able to avoid this, but can control or reduce it.  

Food safety issues: Cross-contamination by means of loose feather or fecal material from the carcasses.
