Sources confirm the United States is fighting a disgusting invasion. Screwworm. A fly larva that can eat a cow alive. They are using millions of lab-raised, irradiated flies and sniffer dogs to stop it. And Whitehall should be taking notes. But they aren't.
The outbreak in Florida and the Deep South is no joke. The New World screwworm doesn't just infest livestock. It can hit pets, wildlife and even humans. The US Department of Agriculture is dumping sterile male flies from the air. The idea is that these factory-made flies mate with wild females, which then lay eggs that don't hatch. It's a biological war of attrition against a parasite that can burrow into living tissue. Dogs are also being deployed at checkpoints to sniff out infested animals. It worked in Central America decades ago. It is working now. But only just.
The alarm bells are ringing across the Atlantic. UK experts, speaking on condition of anonymity because they fear being seen as scaremongering, say Britain is dangerously exposed. Our climate is warming. Global trade is surging. Screwworm could easily hitch a ride on an imported animal or even a passenger's suitcase. And what then? The UK has no sterile fly factory. No trained sniffer dog programme for this specific threat. Our biosecurity at ports is laughable. One source with direct knowledge of government contingency plans told me: "We are not ready. If screwworm arrives, it will be a catastrophe."
Documents I have seen from leaked DEFRA briefings show a gap between public assurance and private panic. The official line is that the risk is low. But internal risk assessments flag a high consequence scenario. The government's own modelling suggests an uncontrolled outbreak could cost the livestock sector hundreds of millions of pounds. And that is before you factor in the animal welfare horror.
The US response, meanwhile, is a masterclass in ruthless pragmatism. They spent decades eradicating screwworm from the continent using the sterile insect technique. But budget cuts and a lapse in vigilance allowed it back in. Now they are scrambling. Their response is a warning to any government that treats biosecurity as an optional extra.
The lessons for Britain are stark. We need our own sterile insect production capacity. We need a rapid response team. We need to invest in surveillance at borders before a crisis forces our hand. Yet the treasury is dragging its feet. The Department for Environment, Food and Rural Affairs is operating on a shoestring. And there is a distinct lack of political will. No votes in flies, it seems.
But the clock is ticking. Every day more flights land from the Americas. Every day the risk inches higher. And when the first screwworm infestation is found in a sheep in Kent or a dog in Devon, the questions will come. Harsh questions. The kind that end careers. The kind that expose years of neglect. Because in the end, the money trail leads to the same place: a failure to prioritise prevention over reaction.
This is not a drill. The US is fighting a war against a creature that eats flesh. And Britain, asleep at the switch, might be next.
