Mr Wing said he had contacted everyone who had bought their milk during the recall period and fortunately no-one had become ill from drinking it.
As soon as they were notified about the potential contamination on August 15 the kiosk was shut down but was able to reopen yesterday after getting the all clear from MPI.
''There's a lot of sleepless nights, when you get a test back like that, but like I said, we talked to everyone who had bought that batch and no-one was ill which was a huge relief.''
Five contamination-free tests of the milk are needed before it is allowed to be sold again.
The contamination scare emphasised the risks of drinking raw milk and people should only buy their raw milk from registered suppliers such as Udderly Fresh, Mr Wing said.
''It's proving the system works but obviously there is always a risk around people drinking raw milk and people just need to be aware of that when they are buying it and make sure the people they are buying it from know what they are doing.''
MPI confirmed there had been no reports of illness but if people who had consumed the milk had any concerns about their health, they should seek medical advice.
New requirements for the sale of raw milk came into effect last year which meant all farmers selling unpasteurised milk had to be registered with MPI, which requires farmers to ask all customers for their contact details.
