''I know they are trying their best, but have they just got enough resources?'' North Otago dairy farmer Peter Borrie asked.
Borrie wondered why samples could not be flown to Australia or even the United Kingdom, if necessary.

Keith Adams runs a beef breeding unit which shares a boundary with one of Van Leeuwen Dairy Group's farms, but not one of the two that returned positive tests.
He wanted to protect his herd and did not think beef farmers realised ''what could happen yet''.

Walter Cameron believed it was in the best interests of New Zealand agriculture to destroy stock on the group's farms. He wanted a show of hands from those attending, who wanted to see that happen, saying it was a major event in New Zealand for dairy and beef farmers.
Former Federated Farmers national president William Rolleston said it was ''far too early'' to have that discussion, while Hunter dairy farmer John Gregan said it was ''not appropriate''.
Rawdon did not believe that Mr Cameron's viewpoint was shared by everyone. ''We will work through a very strict assessment process on each of these farms and try and save as many of them [cows] as we can,'' he said.
