Alert in the United States: a flesh-eating parasite threatens livestock farming, but no new cases have been detected

US authorities are continuing their efforts to contain the spread of the screwworm, a particularly feared parasite whose larvae feed on the living tissue of animals. Following the confirmation of a case in a calf in Texas, no new cases have been reported so far, according to the US Department of Agriculture (USDA).

The discovery of the parasite triggered a major mobilization of veterinary and health services. Authorities implemented surveillance and containment measures to prevent any spread to other farms. The USDA states that operations are actively continuing on the ground.

The screwworm moth poses a major threat to livestock. Its larvae penetrate animal wounds and develop by feeding on living flesh, which can lead to serious injuries or even death if not treated promptly. Historically, this parasite has caused significant economic damage in several regions of the Americas.

Agricultural markets reacted positively to reports that no new outbreaks had been detected. Futures contracts for feedlot cattle rose by more than 3%, as investors believed that immediate risks to the sector could be limited if control measures proved effective.

Despite this cautious optimism, experts warn of the potential consequences of a wider spread. Some estimates suggest that the Texas livestock industry could suffer up to $1,8 billion in economic losses if the parasite were to spread throughout the state.

Health authorities and livestock farmers remain on high alert. The coming weeks will be crucial in assessing the effectiveness of containment measures and verifying that the parasite has been successfully isolated before it can pose a further threat to American livestock.
