New pork preservation
technique developed by
University of Melbourne
THE study, authored by Yu Cao, Robyn Dorothy Warner and Zhongxiang Fang and published in in- ternational journal ‘Food Control’ aimed to investigate a com- bination of nisin/gal- lic acid/chitosan coat- ing and high-oxygen modified atmosphere packaging (HO MAP, 80 percent O2 and 20 percent CO2) on the preservation of fresh pork loin during cold storage (2C ± 1C, 20 days).
A variety of nisin, gallic acid and chi- tosan combinations were trialled on pork loins for their effects on preserving pH, tex- ture and colour; effects on lipid oxidation and protein oxidation; and on minimising bacte- rial growth.
The results of the study showed a combi- nation of all three – ni- sin, gallic acid and chi-
tosan – and HO MAP provided the most ef- fective preservation for samples stored at 2C±1C.
This combination was able to slow the increase in lightness of pork sam- ples, maintain redness and tenderness, reduce lipid and protein oxida- tion and inhibit micro- organism growth.
Application of chi- tosan coating to HO MAP pork loins had antimicrobial and anti- oxidant activities dur- ing cold storage.
The addition of ni- sin alone improved the antimicrobial activity and the addition of gal- lic acid enhanced both antioxidant and anti- microbial properties.
The authors have suggested this combi- nation technique could be used as a cost-ef- fective hurdle packag- ing technology in the preservation of fresh pork.
NATIONAL Farmers’ Federation CEO Tony Mahar said the so-called ‘world’s biggest’ action had failed to have the impact and reach organ- isers desired, reflecting the group’s out-of-touch sentiments.
“These people are op- posed to pets, guide dogs and even aquariums, their views are not representa- tive of the general com- munity.”
However, Mr Mahar said at least one farm and nu- merous supply chain busi- nesses had been subject to invasions, and these stunts were enough to leave the sector feeling frustrated.
“Around 6am on the day, extremists unlawful- ly entered a Queensland dairy, directing explicit language at the farmer and frightening the cat- tle to such an extent they jumped fences.
“Meat processors in Yangan, Queensland; Goulburn, NSW and Laverton, Victoria were also targeted by small groups who chained themselves to equipment and shut down operations
for a number of hours. “We thank the police in these states for acting quickly, and in many cases we are aware the offenders
have been charged.” These actions were ac-
companied by a large event in Melbourne’s central business district, which included obstruct- ing the entrance to the SeaLife Aquarium.
Mr Mahar said Austral- ians had rallied behind farmers throughout the day.
“We’ve been buoyed by the outpouring of sup- port for our farmers, from individuals, from the me- dia and from politicians – including from Prime Minister Scott Morrison, the Attorney General Christian Porter and Ag- riculture and Water Re- sources Minister David Littleproud,” he said.
“We certainly have ap- preciated the well wishes and I have to say, mutual outrage, felt by our fellow Australians.”
Mr Mahar said despite being besieged by chal- lenges such as drought and in some cases floods,
Australian farmers con- tinued to produce safe, quality food and fibre in accordance with world’s best practices.
“We take the respon- sibility of meeting com- munity expectations very seriously and will always commit to doing better where needs be,” he said.
“We are proud of what wedoandhowwedoit, and will gladly welcome visitors to our farm, as long as we are given the chance to officially grant entry.”
Mr Mahar said the NFF was in conversation with the Federal Government about possible avenues of legal recourse and con- tinued to work with its members to implore state governments to toughen trespass laws.
“We acknowledge the Federal Government’s move to recently amend privacy laws to prevent the sharing of farmers’ private address details,” he said.
“We still await action on stripping Aussie Farms of its taxpayer-funded char- ity status.”

African swine fever: conquering Asia, moving in South Africa, smouldering in EU
THE Pork Checkoff, in collaboration with the National Pork Producers Council, American As- sociation of Swine Vet- erinarians, Swine Health Information Center and US Department of Agri- culture, monitor foreign animal disease outbreaks and provide biosecurity information to American producers.
ASF China outbreak countrywide
With the official report coming recently that the island province of Hainan was positive for African swine fever, China is now essentially ASF-positive in its entirety.
In the west, Xinjiang was found to be positive in early April, followed shortly by Tibet.
The only areas not known to be ASF-positive now are the city-based zones of Hong Kong and Macau, which are in the extreme south of China.
Since its discovery in China in August 2018, Rabobank estimates ASF has affected 150 million to 200 million pigs, which is a number nearly 30 per- cent larger than annual US pork production and equivalent to Europe’s an- nual pork supply.
These losses cannot eas- ily be replaced by other proteins (chicken, duck, seafood, beef and lamb), nor will larger imports be able to fully offset the loss.
The firm believes this will result in a net supply gap of almost 10 million metric tonnes in the total 2019 animal protein sup- ply, which could be a lead- ing driver of recent pork import announcements. Cambodia joins Viet- nam as ASF-positive
The recent notice by the
OIE, which flagged Cam- bodia as being positive for ASF, revealed 400 pigs died from the disease and another 100 were culled.
The outbreak is in the northeastern-most Rattan- akiri province bordering Vietnam, which was itself found to be ASF-positive on February 19.
Most of Vietnam’s 556 cases of ASF have oc- curred in this northern area.
Some Vietnamese of- ficials have said the vi- rus may have entered the country via people who brought infected pigs from China or from Chi- na-made hog feed.
South Africa reports new ASF case
In a report by the World Organisation for Animal Health last week, South Africa now has a case of ASF outside of its ASF control zone.
The announcement was triggered by news of a small pig farm in the country’s northwest prov- ince where 32 of 36 pigs died.
Since this was outside South Africa’s control zone for the disease, con- tact with infected wild pigs is suspected. Luxembourg builds wall to keep ASF out
Add the small country of Luxembourg to a grow- ing number of western European nations erect- ing physical barriers to keep ASF-positive wild pigs from entering their borders.
Since it is situated ad- jacent to the ASF-control zone in neighbouring Bel- gium, the Luxembourg Army is building a 20km fence to try to keep its nation free of the costly disease.
Meanwhile, similar
measures have been tak- ing place in France and Denmark.
Japan, Taiwan continue product seizures
Just as Australian of- ficials showed the world earlier this year, officials in Japan have now done the same when it comes to intercepting ASF-positive food products.
Reports cite the recent detection of ASF in two sausages brought into the country by two travellers returning from China.
Likewise, Taiwanese of- ficials have now interdict- ed their 36th meat product infected with ASF, which have all come from China. African swine fever risk calls for action
The global African swine fever outbreak in China is wreaking havoc on the international pork industry.
Fortunately, ASF is not in the US at this time, but the possibility of it or another foreign animal disease means American pig farmers must take the necessary steps to protect their farms and the do- mestic pork industry.
As US pig farmers know, a robust export market is critical to the ongoing success of the na- tion’s pork industry.
In 2018, US pork and pork variety meat ex- ports totalled 5.37 bil- lion pounds valued at $US6.392 billion, accord- ing to USDA.
If a FAD such as ASF entered the US, it would likely eliminate this entire valuation to zero for an unknown amount of time.
Taking steps to prevent it from occurring requires immediate action.
