Queensland researchers are looking at introducing "friendly" bacteria to bagged supermarket salads to prevent potentially deadly outbreaks of salmonella and listeria.
University of Queensland scientists have found bacteria commonly found in fermented foods like sauerkraut and kimchi naturally eradicates bacteria which is harmful to humans.
Associate Professor Mark Turner from UQ said they were now investigating ways to add the good bacteria to fresh foods.
"These bacteria have been eaten by people in fermented foods for hundreds of years, so we don't anticipate there'll be any health effects," Prof Turner said.
"In fact, there might even be some health benefits."
In February, there was a major outbreak of salmonella centred around South Australia, with more than 300 cases recorded.
Prof Turner said they hoped their research would prevent similar cases.
"The vegetable industry are very supportive of this, especially in light of the outbreak earlier this year. It will provide an extra safety hurdle and hopefully we can get some good products out of it."
