Water used post-harvest for product washing or other process where it is in direct contact with the product (including ice) must be deemed as acceptable by the Water Matrix and Risk Assessment. (Revised)

How you will be measured


Risk Assessment identifies any water used in direct contact with the product.


Quality of water used meets the requirements of the Water Matrix.


Any tanks or containers used for storing water are managed to ensure that they do not introduce a microbiological risk.

Risk Assessment



Water analysis is completed by an accredited laboratory, test results are monitored and actions taken on poor results. (Upgraded)

How you will be measured


Evidence that laboratory is accredited to ISO 17025 for microbiological testing of water.


Water test results are available.


Results are compared to the Red Tractor Water Matrix with documented evidence of follow up action if results do not meet parameters.
  • Laboratory accreditation information (paper record or electronic)
  • Water testing results



Where water is recirculated, a documented water treatment process must be in place to ensure the water remains suitable for product contact. (New)

How you will be measured


Water treatment process defined.


Documented records demonstrate the effective implementation of a water treatment process.
