At the close of the year under review the local regulations had been submitted to the DAFF for review and amendment. All proposed amendments and product quality inspectors, to name but a few, were discussed. Key changes to the local standards for potatoes pertain to:

Potato Size groups:

(i) To amend the following primary size groups:

Mixed potato size groups and tolerance levels

It was decided – Not to recommend a “mixed” size group and in the event of non-compliance with the proposed size groups and tolerance levels, that a pocket of potatoes be downgraded to a Class 2 or Class 3.

Quality Factors on the added “Class 3” in the export standards

It was decided to recommend the addition of a “Class 3” in the export standards for all regions.
