Analysis of internal government records shows that thousands of sheep, pigs and cattle were urgently killed after being transported to Australian export slaughterhouses.

Researchers at Curtin University also found that it took nearly 11 hours on average to check injuries and illnesses after animals arrived at the abortion facility - delays "significantly increase the likelihood of animals that require emergency euthanasia".

Last month, the Guardian Australia revealed that cruel cases of animals related to the country's exports were shocking, including deaths from hypothermia in 103 sheep during trucking, and the dog was not punished by state regulators.

The guardian also revealed that the veterinary whistleblower had repeatedly warned the federal government of "deep" oversight of the department, with one complaint alleging that the flawed regime could harm Australia's relationship with its major trading partners.

Curtin University researchers have also been exploring animal welfare issues related to U.S. export slaughterhouses, analyzing 631 welfare incident reports compiled by government veterinarians in 2020 and 2021. The reports were released publicly in 2022 after Greens Senator Mehreen Faruqi raised the impetus to ask them to conduct parlia parlia.

Curtin University researchers said in a paper last week that their detailed analysis of the documents showed “a significant welfare problem for breeding animals arriving at meat export slaughterhouses, especially among pigs.”

The document found that emergency killings were the most common response to welfare events, with approximately 60% of cases or 2,476 animals. On arrival at the slaughterhouse, another 140 animals died.

The researchers also found delays in checking animals after they arrived at the slaughterhouse. The time between delivery and testing takes an average of 10.8 hours, which is most likely due to the animals that have recently given birth.

"For any animal, any animal is in a serious welfare disadvantage, which is obviously a long time," said Professor Clive Phillips, one of the authors of this article.

Phillips said the 631 welfare report shows that a large number of animals encountered serious welfare problems during transportation.

"Overall, about 4% of transported animals are affected by one of these incident reports, and most welfare problems are very serious," he said.

“One of the biggest solutions is due to driver or dog issues, (and) during transport (and) calving and pregnancy; lass feet are a big problem, skin injuries… quite good, all of which have a significant impact on the affected animals, but also on animals that are packed with them.”

The paper proposes a series of reforms, including stronger farm inspections, to identify animals suitable for transporting animals, and to eliminate economic incentives for transporting inappropriate animals.

A federal Department of Agriculture spokesman said regulations on livestock transport are a problem for the state government. The spokesman also said that export slaughterhouses must have appropriate procedures to assess livestock upon arrival.

"If livestock are not suitable for slaughter, appropriate action must be taken," the spokesperson said.

The Guardian's investigation last month showed that the whistleblower filed a series of complaints about the Ministry of Agriculture's plant veterinary system in recent years to monitor animal welfare in export slaughterhouses.

Whistleblowers complained that disturbing animal welfare incidents were not reported to state regulators and that the system was long-term inadequate, leaving some facilities unsurveillance. Another veterinary whistleblower resigned due to a disgusting change, limiting the veterinarian's ability to enter the piano to check animals, which he said prevented him from maintaining animal welfare.

The department rejected the allegations. A spokesman said at the time it had a “strong regulatory framework and, where appropriate, take regulatory action to violate animal welfare requirements”.

The Australian Meat Industry Commission, an industrial peak body, has previously stated that the number of reports of welfare incidents presented in parliament shows the success of the monitoring system and said it is equivalent to "about 0.0058% of the total number of animals treated through export slaughterhouses during this period".
