Another mistake with food exports has jeopardised jobs and triggered calls for an overhaul of meat inspection methods.
In the fifth food trade issue New Zealand is known to have had with China this year, an error with carton labels has stopped a container of meat from entering China.
The labelling fiasco, believed to involve mutton or lamb, meant about 240 workers at Alliance Group's Pukeuri plant in Otago were sent home on Thursday. It is not known when they will be recalled.
Alliance general manager of processing Kerry Stevens said the Ministry for Primary Industries suspended Pukeuri's certification for exports to China last month because cartons in the container were incorrectly labelled.
