Chickens Burned and Buried as Avian Flu Hits the Yucatán
by Patricio Eleisegui
March 21, 2023
Warning: this story contains a graphic image of culled birds.

The chicken farms are already back up and running, a person close to Bachoco farms in the Yucatán region of southeastern Mexico tells me. “Everything was disinfected and the birds were replaced,” he says. Business as usual. The official count of culled birds for the region is 1.7 million. Yet according to interviews conducted with four farm workers, the actual numbers for this current outbreak of avian flu are nearly twice that — 15 mega-farm have slaughtered closer to 3 million infected or potentially-infected birds.

These same sources also say the companies have disposed of the chickens in unsanitary and potentially dangerous ways. Residents who live in Mayan Indigenous villages near the contaminated facilities, including Samahil and Kinchil, report smoke from farms burning culled poultry and heaps of dead birds disposed of in nearby woods. Photographs shared by employees reveal hundreds of dead chickens buried in the woods near farms, with no explanation from regional poultry companies.

The sources interviewed have asked to remain anonymous, fearing the company’s response: “Farm employees are forbidden to talk about what happens,” says one source. “They were threatened with dismissal.”

Yucatán has had the most infected farms in Mexico, with 16 contaminated facilities in total. Most farm workers are back to their regular work schedules, says a source close to the poultry production companies who remains anonymous for fear of recrimination...

...Reports of Residents Consuming Meat

The Mayan communities that neighbor the farms report that some of the specimens infected with avian flu were stolen from the discard areas set up by companies and then consumed by the population.

“I ate a buried chick. I had already eaten some delicious tacos when someone told me ‘that chick you ate was sick,’” said a journalist covering the story. And I stayed like that, with a surprised face. For me the chicken was well cooked, the meat looked normal.” ....
