- A rare New World screwworm infection has been confirmed in a Texas calf, marking the first US livestock case in decades and triggering emergency response measures.
- The flesh-eating parasite poses serious risks to livestock and the agricultural economy, though the threat to humans remains low.
- If larvae infect human tissue, they can cause severe damage requiring urgent treatment, but authorities say overall public risk is currently very limited.
Jakarta – The United States has reported a new case of a flesh-eating parasite known as the New World screwworm, raising concern among agricultural authorities and livestock producers.
A three-week-old calf in Texas was found to be infected with the parasite, marking the first confirmed case in US livestock in decades. The discovery has prompted swift action from federal authorities amid fears of potential economic fallout for the cattle industry.
Although the parasite does not pose a direct threat to food safety, experts warn that its spread could disrupt livestock production and drive up beef prices due to potential large-scale losses.
The New World screwworm is a parasitic fly that reproduces by laying eggs in open wounds of animals. Once the eggs hatch, the larvae feed on living tissue, unlike typical maggots that consume dead flesh.
This distinction makes the screwworm particularly dangerous, as infestations can rapidly worsen, causing deep tissue damage. If left untreated, the infection can lead to severe bacterial complications, organ damage, and even death in affected animals.
According to a report cited by CNN, the case was identified in La Pryor, Texas. The US Department of Agriculture (USDA) confirmed the infection and immediately implemented emergency containment measures.
These measures include quarantining affected areas, restricting livestock movement, and increasing surveillance in surrounding regions to prevent further spread.
Authorities are also accelerating the release of millions of sterile male flies, a biological control method designed to suppress the screwworm population. When female flies mate with sterile males, no offspring are produced, gradually reducing the population.
While cases in humans are rare, health officials emphasize that infection remains possible.
Individuals with open wounds, those working closely with livestock, or people frequently exposed to outdoor environments in affected regions face a higher risk. Even minor cuts or insect bites can serve as entry points for the parasite.
If larvae develop in human tissue, the condition can cause serious damage and requires immediate medical treatment.
Despite these risks, US authorities have stressed that the threat to the general public remains very low at this time.
“We are working together and strictly following animal treatment protocols and movement restrictions,” US Agriculture Secretary Brooke Rollins said during a press briefing on Wednesday evening.
