1.1          The delivery of a clean CTU to the packer is of little use if the CTU becomes recontaminated during its movement within the supply chain. Appropriate measures should be taken to ensure recontamination does not occur. This should include:

• Storing the CTU an appropriate distance away from pest habitats or resident pest populations (the distance will depend on the pest);
• Storing the clean CTU in areas free of risk from recontamination by vegetation, soil, free standing water or unclean CTUs;
• Taking species’ specific measures where quarantine pests are nominated by importing countries;
• Fully paved/sealed storage and handling areas;
• Safeguards should be applied in specific situations to prevent attracting pests such as when using artificial lights, or during seasonal pest emergence periods and occasional pest outbreaks.

1.2        Where CTUs are moved to a storage area, packing area, port of loading, or are transiting through another country, prevention measures should be taken to avoid contamination.
