BAHA Confirms Screwworm Infestation Contained to One Animal in Toledo

On December twenty-sixth, 2024, the Belize Agricultural Health Authority (BAHA) received a report about a suspicious wound on an animal in southwestern Toledo. The wound was suspected to be caused by New World Screwworm, a highly destructive parasite that typically targets livestock and other animals. In response, the Ministry of Agriculture quickly dispatched technical teams to the area for a thorough assessment. Earlier today, the Ministry of Agriculture and its partners held a press conference to share details on their response to the infestation. Here’s Doctor Roxanna Alvarez, Animal Health Director of BAHA, with more information.

“Upon arrival at the farming establishment, a six-month-old Brangus heifer was observed penned in a coral. Closer inspection found a suspicious seeping wound on her right ear near her ear tag. A total of fifty-nine larvae were removed. The wound was treated with Cyperchlor, which is cypermethrin, gentian violet, pine, and citronella oil. Comafuss powder and ivermectin was administered subcutaneous. No other wound was found on the animal and no other animals in the herd presented lesions, wounds, or infestations. The producer was informed that his farm was under quarantine and therefore he would not be allowed to move any animals in or out of the establishment. He was also advised that follow up technical visits would be necessary. He was given advice on treatment and preventative measures for his entire herd. The samples were transported to the BAHA Entomology Laboratory and preliminary findings by the BAHA Entomologist indicated New World Screwworm. We are awaiting confirmation by COPEG. The nearest positive case from the suspected case in Crique Sarco is in Modesto Mendez, Guatemala, which is approximately eleven point eight three miles in a straight line. We have been on high alert for months. As the minister mentioned, we have had an aggressive education and outreach program, coupled with active surveillance. We have done well at preventing infestations, and I must acknowledge the vital role stakeholders have played. In this specific instance, the producer, his neighbors, and the community of Crique Sarco acted with caution, consistently inspected their animals, and immediately notified us. BAHA of wounds with larvae, also known as worms. This was crucial to our immediate response.”
