Butch Moses, from the South Australian Farmers Federation pork committee, says prices for bacon are the highest they've been in years, because a lot of small producers have left the industry.

According to ABC, he says the current conditions are positive but he's cautiously optimistic.

"Prices are bubbling, but sometimes things come off the boil pretty quick too sometimes," he says.

"I guess I just like to wait and see how it goes, but at the moment, we gladly will reap what we can and we won't knock it back by any means."
