Contamination in wool bales are a major problem in the wool industry and it is an ongoing issue.

For the period 04/04/16 to 10/04/17, Cavalier Woolscourers Ltd logged 212 non-wool contamination items in the North Island and 220 in the South island.

This is an average of 8-9 individual items per week.

Not all of the contamination found can be traced back to a farm brand but we do our best to identify the origin.

Metal detectors at both sites have separated out over 800 items in three months alone but non-metal contamination has to be found in the sorting process of the wool in order to be excluded from the finished product.

Cavalier Woolscourers Ltd are working to bring this industry problem to light. Last month, Duncan McKay, Production Manager at Hawkes Bay Woolscourers, a division of Cavalier Woolscourers Ltd, shared an education session on contamination at the NZ Wool Classers Association Day in Gisborne, highlighting the importance of vigilance in all links in the wool supply chain where contamination is concerned.

Struan Hulme, Production Co-ordinator at Cavalier Woolscourers’ Canterbury site highlights the equipment damage that can occur if contamination is not found before the wool is processed through the woolscour. During an interview with Farmers Weekly, Mr Hulme detailed the ongoing problem.
