Feb 3 (Axis negocios) -- The Mexican health authorities imposed three definitive quarantines on broiler farms in the state of Aguascalientes due to the presence of avian flu, a measure that affects a population of 826,000 birds at times when there are concerns about the spread of this highly pathogenic influenza in the American continent.

The affected farms are located in the municipalities of Asientos and Rincón de Romos, some 20 kilometers north of the capital of Aguascalientes, a state in which a generalized quarantine will be established, said the Ministry of Agriculture and Rural Development (Sader) in a release.
"Agriculture urges producers to remain vigilant, notify any suspicion of signs of illness suggestive of avian influenza in their birds and increase biosecurity measures in their production units," authorities said in a statement.

Avian influenza AH5N1 identified in Aguascalientes

Producers must notify any suspicion of the disease

National Service of Health, Safety and Food Quality | March 2, 2023

In order to control the outbreak, Senasica imposed a definitive quarantine on the three poultry production units involved, and will establish internal quarantine in the state of Aguascalientes

Senasica reported the presence of the AH5N1 highly pathogenic avian influenza virus (HPAI) in three broiler farms located in the municipalities of Asientos and Rincón de Romos, Aguascalientes.
In order to control the outbreak, the General Directorate of Animal Health (DGSA) of the Agriculture agency imposed definitive quarantine on the three poultry production units (UPA) involved, which housed 826,800 birds and will establish internal quarantine for the state. from Aguascalientes.
The official veterinarians began the application of the indicated sanitary measures, for which the depopulation, cleaning and disinfection, sanitary vacuum and sentinelization of the three affected UPAs will proceed.
They also began the epidemiological investigation, which involves taking samples from family and commercial farms that are within a 10-kilometer radius of the affected UPAs.
With the purpose of contributing to protect the production of chicken meat and eggs, Senasica invited producers, veterinarians and the general population to immediately notify any suspicion they detect, for which it makes available the telephone number 800 751 2100 and the Avise application, on iOS and Android systems, or they can report at any office of the Ministry of Agriculture, Senasica or CPA coordination, located in all states of the country.

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.” ....

Mexico reported the first case of highly pathogenic AH5 avian flu
On the affected farm, 15 thousand birds have already been sacrificed, Senasica adopted measures to guarantee the production of chicken meat and eggs.
By Omar Tinoco Morales
Oct 29, 2023 11:13 p.m. ITS T

The Ministry of Agriculture and Rural Development (Sader) reported this weekend the first case of highly pathogenic avian influenza AH5 of this season in a poultry production unit in Cajeme, Sonora.

The discovery was carried out by technicians from the National Agri-Food Health, Safety and Quality Service (Senasica) in the laboratory located in Hermosillo, Sonora.

The affected farm has 90 thousand laying hens, of which 15 thousand birds that are considered end-of-production cycle hens have already been sacrificed.

The vaccination strategy could begin in the first days of November, in areas of high animal health risk and in farms that are dedicated to raising parent and reproductive hens, because they are essential to preserve the production of chicken meat and eggs for supply. national.

Therefore, technicians from the Mexico-United States Commission for the Prevention of Foot and Mouth Disease and other Animal Diseases (CPA) of Senasica were mobilized to the area, with the purpose of diagnosing the situation and applying the measures. counter-epidemic measures necessary to contain the spread of the virus.

According to Sader, among the first measures adopted, the General Directorate of Animal Health (DGSA) declared a total definitive quarantine of the affected farm and the state of Sonora in internal quarantine, which implies that to mobilize birds from the poultry production units ( UPA) of the entity it is necessary to present PCR proof that demonstrates the absence of the disease.

In addition, the DGSA reported that the Senasica laboratories are carrying out the necessary tests to have more data on the virus that affected this farm, to which hens previously vaccinated with the immunogen applied the previous year will be exposed.

Once the effectiveness of the biological to protect birds from the strain that entered this year is proven, Senasica will authorize the strategic application of the vaccine in Sonora.

Birds may also be vaccinated in areas of high poultry production, at the request of producers who wish to do so, for which they must demonstrate with laboratory studies that their birds are free of the virus and have the service of a responsible veterinarian authorized by the Senasica.

The Ministry of Agriculture also reported that epidemiological surveillance actions continue and that, if necessary, the National Animal Health Emergency Device will be activated, to enhance control actions and, where appropriate, eradication of avian influenza. of high pathogenicity A, subtype H5N1, as well as to prevent its spread throughout the national territory.

In the field investigation carried out by official personnel, it was observed that 40 meters from the farm there is an irrigation canal with an abundant number of migratory ducks, so it is necessary to take extreme biosafety measures to avoid new infections.

Senasica recalled that the main preventive practice is the application of strict biosafety measures in poultry farms, while vaccination is a tool to control the virus. Therefore, he urged producers to increase their actions on farms, in order to protect national poultry production.

It is necessary, the agency noted, to establish health protocols for people who enter the UPA, wash and disinfect all vehicles; use sanitary mats at the main entrance and in each house and check the flock daily to detect birds with suggestive clinical signs.

It is also essential not to move sick or dead birds, which must be isolated or, where appropriate, disposed of sanitarily and implement procedures for the control of wildlife and elimination of harmful fauna.

The Ministry of Agriculture reiterated the call to promptly notify any suspicion of the presence of the virus on its farms.
