Several batches of Udderly Fresh Raw Milk could contain campylobacter and has been recalled.
Batches 294 to 303, with a use-by date of August 18 to August 27, have been recalled. It is in IL glass bottles or customer-supplied containers and is sold via a vending machine at the company's farm at 342 Kane Road, Hawea Flat, Wanaka.
The recall does not affect any other batches.
Campylobacter symptoms can range from diarrhoea and lethargy, to fever and abdominal pain that can last several weeks.
According to the Ministry for Primary Industries (MPA), there have been no reports of illness but if you have consumed one of the batches, it is advised that you seek medical advice.
Customers are asked to check the batch number and date mark on the sticker placed on the bottle.
MPI says raw, unpasteurised milk from any animal carries risk.
Between 2009 and 2015, there were 41 outbreaks of illness in New Zealand where consuming raw milk was a factor. And 90 percent of the cases involved children aged between one and 16.
Young children, the elderly, people with weakened immune systems and pregnant women are most at risk.
