Specialist cheesemakers say the success of supermarket Aldi at the Sydney Royal Cheese and Dairy Show will devalue the awards.
Aldi won 49 medals at the awards, including eight gold, and was named the competition's most successful dairy exhibitor.
But president of the Specialist Cheesemakers' Association, Carla Meurs, says the awards may mislead consumers as they don't give any information about who is actually making the cheese.
"It's a problem across the whole food industry and now in the cheese industry as well, where we have supermarket rebranding or using generic brands for cheese products that are often actually produced by small manufacturers or medium manufacturers in Australia," she said.
"There needs to be some work done on this because it's not helpful."
Victorian cheesemaker Berrys Creek won champion cheese at the awards. But Ms Meurs said Aldi's domination of the competition will make cheesemakers reluctant to enter further Royal Agricultural Society competitions.
"I think it will have a big impact on cheesemakers and other dairy products being entered to the show, absolutely," she said.
"I don't think it's helpful for a cheese show to just be representing a generic brand that means nothing as to the origin of that product."
Aldi wasn't able to provide details as to who produces its award winning cheeses except to say that they are made in Australia.
Cheese judges say this lack of information about who makes these cheeses is a big problem for consumers.
"It's not really a fair thing to take a Ferrari or a Lamborghini, take the badge off it, put your badge on it and claim it's your car," said Ian Roberton, former chief judge of the Australian Speciality Cheesemakers Association.
"They're clearly going to win but I want to know who made the car," he said.
The Royal Agricultural Society of NSW didn't respond to ABC Rural's request for an interview.
