Newcomb Barrenador Worm Infestation Threatens Livestock Economies in Central America and Mexico

The Newcomb Barrenador worm infestation poses a significant threat to livestock farmers across Central America and Mexico, with devastating economic repercussions. Since late 2024, the Mexican livestock industry has reported losses exceeding 14 billion pesos, primarily due to the infestation that has delayed the export of approximately 400,000 heads of cattle, resulting in an estimated loss of about 700 million dollars [d35e7c1b].

In response to this crisis, Tey Mollinedo Cano is organizing a forum scheduled for March 14, 2025, aimed at discussing prevention and control measures to combat the infestation [d35e7c1b]. Karina Margarita del Río Zenteno has emphasized the urgent need for legislative action to address the situation effectively [d35e7c1b].

The National Service of Health, Food Safety and Quality (Senasica) has reported 14 outbreaks of the Newcomb Barrenador worm in Chiapas, prompting Secretary of Agriculture Julio Berdegué to announce efforts to release sterile flies as a biological control method [d35e7c1b]. Farmers are being urged to closely monitor their livestock and maintain hygiene practices to mitigate the spread of the infestation [d35e7c1b].

Additionally, there have been nine reported human cases of infection in early 2025, primarily affecting men and older adults, highlighting the public health implications of this agricultural crisis [d35e7c1b]. Humberto Hernández has stressed the importance of coordination between farmers and health officials to effectively manage the situation and protect both livestock and community health [d35e7c1b].

As Borno State in Nigeria invests in revitalizing its livestock economy with a ₦1.5 billion initiative, the challenges posed by the Newcomb Barrenador worm infestation serve as a stark reminder of the vulnerabilities facing livestock industries worldwide [46be0776]. The combined efforts of local and national authorities in both regions could provide valuable lessons in addressing agricultural crises and ensuring food security [8eb7e4f4].
