Screwworm fly remains unstoppable in Yucatán; over 2,259 animals affected

The parasitic screwworm fly continues its relentless spread in Yucatán, Mexico, affecting a growing number of animals. The Secretariat of Rural Development (SDR) reported that 2,259 animals have been impacted since the outbreak began, with the numbers still climbing.

To combat the infestation, authorities have been releasing sterile flies over the past two weeks. Edgardo Medina Rodríguez, head of the SDR, urged producers not to let their guard down. He stressed the importance of continuing to monitor livestock and report any signs of infestation to the authorities.

Nationwide, reports from the National Service of Health, Safety, and Agri-food Quality (Senasica) in early July confirmed 32,290 cases of myiasis in both livestock and domestic animals across 28 states. This widespread issue highlights the significant agricultural and economic threat posed by the pest.

Compounding the problem, Yucatán has also seen an increase in human cases. The federal Ministry of Health confirmed two new cases of myiasis in humans in the state during the first week of July. This brings Yucatán's total human cases to 36 since the disease's resurgence, ranking it fourth nationally. The state is among the areas with the highest incidence of this disease, with Veracruz and Puebla reporting more cases.
