A Cornell University project is investigating when wash, dry and wax brushes in packinghouses should be replaced.
Natural wear of these brushes can make cleaning more difficult and increase the risk of Listeria monocytogenes cross-contamination.
The research aims to establish clear indicators of deterioration to support industry decisions on replacement timing.
The goal is to balance food safety with the operational costs of replacing equipment.
The study includes steam-based trials to improve sanitation effectiveness at different wear stages.
Results are also being evaluated in commercial apple packinghouses to validate real-world application.
