The Ministry for Primary Industries says it is exploring interim measures to strengthen consumer assurances about dairy production after the recent food contamination scares.
The ministry's move follows an announcement on Monday from Hokitika-based Westland Milk Products that a small amount of lactoferrin powder had been quarantined in China after tests there showed it contained higher-than-permissible nitrate levels.
Among the measures proposed, the ministry said it was looking at raising the "regulatory presence" at dairy manufacturing sites.
"Our dairy sector trades on New Zealand's reputation, and that reputation is built on the strong assurances our regulatory system provides, and the quality of New Zealand's products," said the ministry's acting director-general, Scott Gallacher.
"The reality is the convergence of events over the last six months has sparked debate about some elements of our food system. We need to respond to that."
