Raspberry fruit juice cordial can kill the virulent bacteria that causes outbreaks of gastroenteritis, research shows. Experiments with pure raspberry juice and commercial cordials at Charles Sturt University in Wagga Wagga have shown that a folk remedy commonly used by livestock owners has scientific validity, Dr Heather Cavanagh said.
Dr Cavanagh and colleague Dr Jenny Wilkinson from the school of biomedical sciences have found that a dash of concentrated raspberry juice kills E. Coli, salmonella, mycobacterium and staphylococci among other bugs. “We’ve looked at raspberry juice and raspberry cordial with at least 25 per cent juice and they both work very well,” Dr Cavanagh told AAP.
“Raspberry-flavoured cordials do not have the same effect, and when we tried the juice on fungus it just grew better, probably due to the sugars.”
Dr Cavanagh, who hails from Scotland, was startled to find that Australian cattle and pig farmers routinely use raspberry cordial to prevent gastric outbreaks in their animals, as well as recommending it for people.
“Apparently farmers in the Riverina when their cows start to develop gastroenteritis, instead of calling the vet they just tip a couple of litres of raspberry cordial into the trough,” she said.
“I also had a call from a pig farmer who claims the mortality in his piglets dropped from 40 per cent to zero by using cordial.”
The Budgerigar Council of Victoria recommends on its website a one in 10 dilution of raspberry cordial to prevent infection in breeding stock.
Dr Cavanagh, who is researching the medicinal properties of a range of herbal remedies, has not yet identified the active antimicrobial ingredient of raspberry juice.
Her research shows it’s either not present or not potent in the leaves of the raspberry bush, traditionally taken as tea for a range of medical complaints, including diarrhea in children.
Salmonella and other bacterial infections survive well in water, contributing to the rapid spread of gastroenteritis in communities such as schools and childcare centres, and being a major problem in developing countries. They are not always treated with antibiotics but resolve with high fluid intake.
“What we’ve shown in our in-vitro research only applies to prevention, not cure,” Dr Cavanagh said.
“But I have been approached today by someone who wants to do a clinical trial in India and if we do that we may be able to show that it is a treatment as well.” Dr Cavanagh said the bacteriological evidence so far suggested that a 35 per cent pure juice cordial at up to a 1:10 dilution may aid in preventing transmission of gastric bugs through contaminated water.

Saturday, March 24, 2001 - “BUDGIE NEWS” JANUARY/FEBRUARY. 1987.
From a write up in “Australian Post”, and from other sources, we have learned that early last year, cordial makers, Anchor Foods, in South Australia, discovered an untapped market of four million new customers a year. It all started as a result of a chance discovery by a Perth based team of scientists, led by Michael Gracey, Associate Professor of Child Health at the University of Western Australia.
Professor Gracey and his team had been looking for a simple, cheap and effective way of providing drinking water that was safe from bacterial contamination. Suspecting that cordial might be implicated in intestinal infections, they set out to see if they could grow the dangerous bacteria in various cordials.
They were amazed to discover that exactly the opposite was true. All of the cordials they tried, but particularly Anchor and Cottees Low Calorie, made short work of Salmonella, E. Coli and even the dreaded Vibrio~Cholerae, killing the bacteria in a matter of seconds. Anchor hadn’t considered using cordial to combat diarrhoea in animals until February 1985, when a Western Australian farmer, Keith Davey, got in touch with their office in Western Australia to tell them he wanted to buy raspberry cordial in bulk to feed his piglets.
He had seen the initial publicity about Professor Gracey’s findings and reasoned that cordial could work with pigs as well, because their digestive system is very similar to that of humans. Apparently gastric problems are very common in young pigs, with high mortality rates.
After experimenting with various flavours, Davey asked Anchor to settle on raspberry because all the others contained fruit particles which clogged up the teats of his piglets feeding equipment. The results he claimed to obtain could not have been more impressive. The mortality rate amongst his piglets dropped from around 4% to virtually nothing and his feed bill was halved.
Eventually Anchor developed a dry powder that could be added to water and this is a concentrated raspberry drink powder called “AWS 111” which has now been released on to the market. Silly as it may sound, farmer Keith Davey has been feeding his piglets raspberry cordial morning, noon and night, and pig farmers, and others too, all round Australia are following his lead.
In the future this unusual application could be extended to include chickens, horses, cattle, greyhounds, etc.
Here in Sydney, and I believe also in Brisbane and Melbourne, numbers of canary breeders are getting on the bandwagon this year in the belief that AWS 111 raspberry solution will help them reduce mortality in their baby canaries this breeding season, and there is every reason to believe that AWS 111 added to the drinking water will do just that.
The theory advanced is that any bacteria received into the water from the parent bird’s beak, will be killed within seconds, so that the adult birds and the chicks are drinking bacteria free water at all times.
Last breeding season, one of our members, the very prominent Norwich breeder, Ross Vincent, had his best year since 1981, with 80 odd youngsters and he gives full credit of his success to the use of raspberry cordial in the drinking water. He is completely sold on it and many others are now following his lead. The manufacturers say it is important to note that the use of their product is not a replacement for good management practices, especially hygiene.
It is not a magic panacea, as it will not clean up a dirty operation.
Brig Pitman advised that Anchor raspberry diet cordial, 2 litre bottle has natural sugar in it and is cheaper to purchase than AWS 111. It is diluted in the drinking water 1:10.
