A catastrophic infestation of mice is sweeping through eastern Australia, decimating crops and threatening to disrupt British agricultural imports. The plague, which began in the grain belts of New South Wales and Queensland, has now spread to Victoria, prompting emergency measures from Canberra.
Farmers report losses of up to 40% of stored grain, with mice destroying machinery, contaminating feed, and gnawing through electrical wiring. The economic toll is estimated at A$1.2 billion, with supply chains for wheat, barley, and canola severely affected. Australia supplies roughly 15% of Britain’s wheat imports, and disruptions are already being felt in London trading floors.
“This is the worst outbreak in living memory,” said Dr. Andrew Green, an agricultural ecologist at the University of Sydney. “The mice have bred unchecked due to a combination of favourable weather and a bumper harvest, creating ideal conditions for population explosion.”
The crisis has sparked a political row over the use of the banned poison bromadiolone, which the government recently reauthorised for emergency use. Environmental groups warn of secondary poisoning of native wildlife, while farmers demand more aggressive action.
British trade officials are monitoring the situation closely. The Department for Environment, Food and Rural Affairs has convened an emergency meeting with importers to assess the impact on food prices. A spokesperson said, “We are in contact with Australian authorities and preparing contingency plans to mitigate supply disruption.”
The outbreak underscores the vulnerability of global food systems to ecological shocks. For Britain, it highlights the fragility of post-Brexit supply chains, which rely increasingly on distant sources. With climate change expected to increase the frequency of such events, the question is not whether these plagues will recur, but how resilient our food networks will prove.
As the Australian summer approaches, the crisis shows no sign of abating. The mice are now moving into coastal cities, forcing residents to seal homes and businesses. The prime minister has described the situation as a “national emergency”. For British consumers, the first sign of trouble may come in the form of rising bread prices by early autumn.
