Avian influenza AH5N1 generates alert, it is already in Mexico and not October 16, 2022

The new variant of avian influenza AH5N1, considered highly contagious, was detected in the State of Mexico on October 14. The case is considered the first in Mexico, which alerted the authorities to take precautions within the poultry industry and the population in general.

According to reports from the National Service for Agrifood Health, Safety and Quality (Senasica), the virus was found in a gyrfalcon that died hours later in isolation. According to the institution, the animal was found near the Lerma River in the State of Mexico. He underwent several laboratory tests to confirm if he was a carrier of the new variant of avian influenza AHN51...

EPIDEMIOLOGICAL COMMENTS

This report represents the first isolation of a HPAI virus subtype H5N1 in Mexico, which occurred in a non-poultry bird and in one of the migratory wild bird corridors that cross the country, with no cases detected so far in backyard and commercial birds. As anti-epidemic measures, risk areas have been defined and a situation diagnosis is being carried out through epidemiological tracing in the focal and peri-focal zones, with the objective of identifying new cases. Notification of suspected cases is encouraged through local authorities and personalized visits to backyard poultry farmers, and poultry producers are invited to reinforce their biosecurity measures and report any abnormal behavior in their flocks.

Hundreds of birds die in Laguna de Xico due to H5N1 influenza
History of Alejandro León • Yesterday at 19:25
Due to the avian influenza virus, approximately 797 wild ducks died in the Xico Lagoon, which covers the Tláhuac Mayor's Office, in CDMX, and the Chalco Municipality, in the State of Mexico.

According to a report shared by the Tláhuac Mayor's Office, on November 10 the National Water Commission (Conagua) reported high morbidity and mortality of ducks in the Laguna wetland.

With this, the United States-Mexico Commission for the Prevention of Foot-and-Mouth Disease and other Exotic Animal Diseases (CPA) went to the place to obtain samples that were analyzed in the laboratory.

Thus, on November 14, the presence of the highly pathogenic H5N1 avian influenza virus was confirmed.

Authorities detailed that to prevent the persistence of the virus in the wetland, 65 trained technicians carried out sanitation work by collecting 792 dead wild ducks, which were buried.

"Activities carried out from November 22 to December 1, so far, the AI H5N1 virus has not reached backyard birds, so timely notification of suspected cases continues to be encouraged," the authorities said.

They added that workers also visited backyard farms and veterinary pharmacies of the Tláhuac Mayor's Office, as part of the sanitary prevention and control measures that they applied.

Hundreds of birds mysteriously found dead at undisclosed location
Authorities are racing to determine the cause of the bird deaths
Michael Dahlstrom·Environment Editor
Mon, 12 June 2023 at 3:16 am GMT-4·2-min read

Hundreds of dead birds have been found on Mexico’s Pacific coast, prompting an investigation from authorities.

Few details about the event have been released, and the exact location – as well as the cause – remain a mystery.

Images taken on Saturday and supplied by the government indicate the situation is being taken seriously. Technicians from the National Service of Health are seen wearing protective clothing.

One photo shows the water is a putrid green colour near the shore. A second image shows a man holding a seabird, possibly a cormorant.

What could have killed the birds?

While it is too early to speculate as to the cause, bird deaths can be a sign of a disease outbreak. The H5N1 strain of avian influenza spreading across the globe has killed tens of millions of birds, harming both wild and domestic populations. It has also infected 17 mammal species and in February it claimed the life of an 11-year-old girl...

Bird mortality alarm on beaches of the Oaxaca Coast

Written by Red Zone Agency June 11, 2023

Writing/Red Zone.
Oaxaca de Juárez, Oax., June 11, 2023.-
Hundreds of seabirds died in recent days on the Oaxaca Coast and so far there is no certainty of the cause.
In a statement, the Universidad del Mar reported that the event occurred on beaches such as Palmarito, Escobilla, Ventanilla, Agua Blanca and Guapinole; In the first two, researchers from the institution made records.
He indicated that for all the records they have collaborated with the Mexican Turtle Center and the cooperatives "Vivemar", "Lagarto Real la Salina" and residents of the area.
"As a result of this situation, researchers from our institution performed necropsies on fresh cadavers and biological samples were sent to the laboratories of the National Center for Diagnostic Services in Animal Health (Cenasa), through the Coordinator in Pinotepa Nacional of the Mexico- United States for the prevention of Foot-and-Mouth Disease and other exotic animal diseases (CPA), on suspicion of
viral diseases.
“Last night (Friday) we received the results issued by the
Cenasa laboratories, which are negative for avian influenza (H5N1) or Newcastle disease, "he said.
However, given that the origin of these bird deaths is still being studied, the Universidad del Mar suggested the following preventive measures to the community:
* The general population is asked to avoid handling or contact with live seabirds and with apparent clinical signs of disease, as well as to prevent pets from approaching animals or carcasses.
* In case of finding dead or sick specimens on the beach, please notify the authorities or our institution, providing as far as possible photographs as well as information about the locality.
* For the authorities or persons in charge of removing birds from the beaches, the Biosafety Protocol for the Management of Wild Birds in Naturally Protected Areas must be followed (Zonnosis mitigation and privations).
*Deposit the corpses in pits approximately 1.5 m deep, and cover with lime and close the pit.
The University explained that it is necessary for those who carry out these measures to be duly protected, with gloves, glasses, face masks and, if possible, shoe protection, as well as use plastic bags for the transfer of corpses.
“Universidad del Mar has been actively working to address this contingency since last Tuesday, June 6, supporting the responsible government agencies with information and analysis, in close collaboration with the communities of the region, always strictly adhering to validated data. scientifically," he said.
THE OFFICIAL VERSION
For its part, the State Government issued a statement yesterday, through the Oaxaca Health Services (SSO), in which it announced that the monitoring protocol, intensified surveillance and comprehensive preventive actions were activated in Health Jurisdiction number Cuatro Costa, due to the mortality of seabirds and fish on the beaches of Palmarito, Escobilla, Ventanilla, Agua Blanca and Guapinole, as well as in the Zapotalito Lagoon.
The Directorate for Health Regulation and Promotion, Prevention and Health Promotion, and the Intelligence Unit for Health Emergencies (UIES), as well as the National Service for Health, Safety and Food Quality (Senasica) and the State Committee for the Promotion and Livestock Protection of the State of Oaxaca (Cefppo), held a meeting to establish the actions to be taken in response to this alert.
He explained that the institutions work in a coordinated manner for the correct final disposal of the specimens, the analysis of samples to determine the causes of mortality, as well as analysis in the water to identify possible cells or toxic microorganisms.
In addition, monitoring of the areas where these events were reported will be strengthened; The entire medical network in the region is on alert for health care in cases that could be related to this event.
"Citizens are urged to remain calm, not disseminate unofficial information and in the event of finding a dead bird or fish in these locations, avoid handling it and stay informed through the official channels of the institution and the State Government" , he stated in his statement.

Los Cabos, without cases of birds killed by avian influenza

300 birds killed by H5N1 avian influenza have been found on Mexican Pacific beaches

Aaron Romero | The South Californian

La Paz, Baja California Sur. (OEM-Informex).- The Department of Ecology and Environment of the City of Los Cabos has not detected any stranding of dead birds on the beaches affected by H5N1 avian influenza.
The biologist Roberto Díaz Flores, director of Ecology and Environment of the Los Cabos City Hall announced that up to now the monitoring area for the protection of sea turtles on beaches and coastlines has not found any stranding of dead migratory birds in the beaches near San José del Cabo and Cabos San Lucas, therefore Los Cabos is still considered to be free of the avian influenza virus...

..... NEW VARIANT

He explained that the H5N1 avian influence has always existed in birds but it could be due to a variant of the strain of that same virus that is causing mortality on the coasts of other Mexican Pacific states for which they remain on alert according to the protocols established for the handling of species infected by high-risk pathogens, which require handling with specialized equipment.
He explained that the protocol that must be carried out by the Department of Ecology and Environment of the City of Los Cabos is only monitoring and in case of finding dead stranded birds with the characteristics of being carriers of avian influenza, very careful management must be taken so that they do not there is spread of the bird disease and immediately notify the National Agrifood Health, Safety and Quality Service.
...After the National Service of Health, Safety and Food Quality, (SENASICA) the Ministry of Agriculture and Rural Development (SADER); The National Commission for Natural Protected Areas (CONANP) and the Ministry of Environment and Natural Resources (SEMARNAT) issued an alert for the Mexican Pacific H5N1 avian influenza on beaches in Chiapas, Oaxaca, Guerrero, Michoacán, Jalisco, Sonora and Baja California Sur ....https://www.elsudcaliforniano.com.mx...��

Investigate death of birds on Sonora beaches for alleged avian flu

Byfernanda romero
June 13, 2023

Different government authorities are investigating the death of dozens and different species of birds on the coasts of the Mexican states, including Sonora.
The Secretariats of Agriculture and the Environment are working to detect the cause of death, which apparently is due to the highly pathogenic AH5N1 virus or bird flu.
They have reported the death of wild birds in the strip of the Mexican Pacific coast and coastal environments, from Chiapas to Sonora.
Specialists from the National Food Safety and Quality Service (Senasica) traveled to the beaches of Chiapas, Oaxaca, Guerrero, Michoacán, Jalisco, Sonora and Baja California Sur where personnel from the National Commission of Protected Natural Areas (Conanp) reported sightings of birds sick and dead.
So far, the investigations have revealed around 300 dead birds of various species.
There is a suspicion that it could be the highly pathogenic AH5N1 virus, which can be carried by seabirds on their migratory return to North America.
This is because, at present, South American countries present viral activity by this pathogen.
The situation must be confirmed or ruled out through laboratory tests by the animal health authorities of Mexico.

The health authorities of Agriculture ask to immediately report any sighting of dead or sick birds to the emergency telephone number 800 751 2100.

Heat wave causes high bird mortality in the Mexican Pacific: Semarnat

The death of birds from Chiapas to Baja California is a consequence of the high temperatures caused by El Niño and not of bird flu, concludes a Senasica opinion.

• AN/JOF Writing

15 Jun, 2023
The high temperatures that plague the country are causing a high mortality of birds on the coasts of Mexico and the tests that have been carried out rule out that it is deaths from avian gravel.


This was reported by the Secretariats of Agriculture and Rural Development (Sader) and Environment and Natural Resources (Semarnat).


Both agencies explained that in the face of the death of birds on the Mexican Pacific coast they mounted an investigation operation to determine the cause of death of seabirds with tests carried out by the National Agri-Food Health, Safety and Quality Service (Senasica).


Based on the foregoing, and derived from the first tests, Sader and Semarnat concluded that the death of birds is not due to the presence of New Castle disease and highly pathogenic avian influenza AH5N1, also known as bird flu.


Within this framework, Senasica reported that the collection of tissue samples from dead birds continues and explained that after carrying out an analysis of the pathological findings found in the necropsies carried out by veterinarians and specialist biologists, it was concluded "that the animals died of starvation". .


The opinion adds that the most probable cause of the death of the birds "is the warming of the waters of the Pacific Ocean, due to the effects of the El Niño meteorological phenomenon, which causes the fish to go down to the depth in search of deeper waters. cold, a fact that prevents seabirds from hunting for food.


Avian flu ruled out, birds starve to death


The Senasica analysis indicates that more than 90 percent of the affected animals are gray-backed shearwaters (Puffinus griseus), although other endemic species such as gulls and pelicans have also been found.


“Grey-backed shearwaters are birds that usually live in the high seas and breed on islands, they rarely reach the continental surface, they can fly up to 500 kilometers a day, which is why they require high amounts of food to survive and, at this time, they do not find enough fish on the surface of the sea to cover their energy needs, so they die in the ocean and reach the coast dragged by maritime currents”, the opinion states.


The document adds that the high mortality of seabirds has occurred in other latitudes of the world when the El Niño climate event occurs and, in fact, deaths of seabirds have also been reported in Peru and Chile.

Fifteen veterinarians and official biologists from the United States-Mexico Commission for the Prevention of Foot-and-Mouth Disease and other Exotic Animal Diseases (CPA), as well as from the General Directorate of Animal Health (DGSA), have collaborated in the analysis.


Bird mortality tests have been carried out in the states of Chiapas, Oaxaca, Guerrero, Michoacán, Jalisco, Colima, Nayarit, Sinaloa, Sonora, Baja California and Baja California Sur, with the support of various federal, state and municipal institutions.

The biological samples collected by the specialists are sent for analysis to the CPA's National Center of Reference for the Diagnosis and Research of Exotic and Emerging Animal Diseases, which includes high-security level three laboratories.


Subsequently, they are referred to other Senasica facilities, such as the National Center for Animal Health Diagnostic Services (Cenasa) and, if necessary, to the National Reference Center for Animal Parasitology and Analytical Technology (Cenapa), to carry out complementary tests that to detect the presence of other infectious or toxic diseases that may be present.


Given the health alert, Sader and Semarnat called on the general public to report high bird mortality to the health authorities by calling the emergency telephone number 800 751 2100, available 24 hours a day, 365 days a year, or through the Advise application of Senasica.

Mexico reports H5N1 bird flu in wild duck, commercial farms unaffected
Reuters
October 5, 202312:35 AM EDTUpdated 6 hours ago

MEXICO CITY, Oct 4 (Reuters) - Mexican animal safety authorities confirmed the first case of H5N1 avian influenza in a wild bird on Wednesday, after declaring the country's poultry farms free of the virus earlier in the day.

A case of H5N1 avian influenza was found in a "clinically healthy" migratory duck in the state of Jalisco, the animal safety agency Senasica, which is part of the agriculture ministry, said in a statement.

Earlier, the government declared in its official gazette that the country was H5N1 free, almost a year after starting a bird vaccination campaign in high-risk areas to prevent its spread.

Senasica stressed that the confirmed H5N1 case does not signal an outbreak of the disease or contradict that declaration but instead it means that poultry farmers should be on alert to prevent the entry of infected wild birds....

Agriculture urges poultry farmers to reinforce biosecurity measures at the start of the bird migratory season

The National Agri-Food Health, Safety and Quality Service (Senasica) reported the first case of AH5N1 avian influenza in a clinically healthy wild bird, which was located in the wetlands of Tototlán, Jalisco.

Ministry of Agriculture and Rural Development | October 4, 2023 | Release


The National Agri-Food Health, Safety and Quality Service (Senasica) reported the first case of AH5N1 avian influenza in a clinically healthy wild bird, which was located in the wetlands of Tototlán, Jalisco.

B463/2023


Mexico City, October 4, 2023.

• The National Agri-Food Health, Safety and Quality Service (Senasica) reported the first case of AH5N1 avian influenza in a clinically healthy wild bird, which was located in the wetlands of Tototlán, Jalisco.

• To prevent the entry of wild birds, producers must reinforce security measures on their farms, with actions such as: closing doors, cracks and placing bird netting on the perimeter of the houses that house the birds in production.

• The discovery does not represent an outbreak of the disease nor does it affect the status of a free country. This is an ecological case that, in accordance with the guidelines of the World Organization for Animal Health (WHO), only considers the mandatory notification of confirmed cases in production units, but it should be considered as an alert to poultry farmers.

Given the beginning of the autumn-winter season, which involves the migration of birds from the United States and Canada to the center and south of the American continent, the Ministry of Agriculture and Rural Development urged poultry producers to reinforce biosafety measures in their farms and backyard units and immediately notify the health authority of any anomaly they observe in their animals.

Derived from the epidemiological surveillance work carried out by the National Agri-Food Health, Safety and Quality Service (Senasica) in the 32 states, specialist doctors from the General Directorate of Animal Health (DGSA) confirmed, in the wetlands of Tototlán, Jalisco, a migratory bird that tested positive for the AH5N1 avian influenza (AI) virus.

The carrier species is a duck known as the green-winged teal, of the species Anas crecca, which at the time of its capture was clinically healthy.

The management of the Mexico-United States Commission for the Prevention of Foot and Mouth Disease and other Animal Diseases (CPA) of the DGSA highlighted that so far no mortality of wild birds or backyard birds has been reported in the region of the discovery.

The Agriculture agency issued a statement to poultry producers in the region to notify the first case of AI in the official Senasica laboratories, through the RT-PCR test.

The DGSA stressed that migratory ducks and geese do not visit poultry farms, however, in the wetlands where they spend the night to feed and rest, they can coexist with other resident birds that can become infected and visit poultry farms that do not have protection measures against them, such as bird nets.

According to official data from the Agriculture Agency, around 19 percent of the farms in the country do not have optimal biosecurity measures, because they have open doors, holes in roofs and any gap through which wild birds can enter the interior of the farm. a booth that houses those that are in production.

For their staff, these types of units must implement at a minimum: mandatory baths with a change of clothes to enter the farms, reinforce the aviary nets and keep the doors closed, in order to prevent the entry of resident birds that may be infected, like grackles and sparrows.

Senasica reminded poultry farmers that all commercial farms must have an authorized responsible veterinarian (MVRA) under contract in poultry production units, to verify compliance with official animal health provisions and to notify the CPA, of immediately, any increase in bird mortality or decrease in egg production.

The DGSA reiterated that at this time emergency vaccination against the AH5N1 virus is not an authorized option, until Senasica completes the virus isolation studies in chicken embryos, the intravenous pathogenicity index, genomic sequencing and challenge in immunized birds, coupled with risk analysis studies that will define the epidemiological image, from which the appropriate measures will be determined, which, if necessary, would include strategic vaccination in high-risk areas.

This finding does not represent an outbreak of the disease nor does it affect the status of a free country. This is an ecological case, since, in accordance with the guidelines of the World Organization for Animal Health (WHO), it only considers the mandatory notification of confirmed cases in production units, however, it should be considered as an alert to the poultry farmers.

The AH5N1 AI virus was eradicated from Mexico during the last winter season, through the National Animal Health Emergency Device (Dinesa), which established strict measures for its control and elimination, with actions that considered the sacrifice of around 5.5 million of birds to protect the national flock.

According to the National Poultry Farmers Union, Mexico's poultry production has a value of more than 198 billion pesos, the result of the manufacturing of 6.7 million tons of poultry products annually, so the cost-benefit of Dinesa's actions for eradication they meant 0.33 percent of the value of national poultry production, without affecting the price of eggs and chicken for the consumer.

It is important to remember that biosecurity is the best protection against avian influenza, and it is a poultry farmer's obligation to protect their flocks.
To report the suspicion of the presence of an exotic animal disease or pest, Senasica makes available to producers and the general population the telephone number: 800 751 2100, available 24 hours a day, and the Avise application, usable on iOS and Android systems.
Also, they can report at any office of the Ministry of Agriculture, Senasica or the CPA, located in the 32 states.

EPIDEMIOLOGICAL COMMENTS
As a result of the epidemiological surveillance carried out by Senasica in the 32 States, specialists confirmed one additional outbreak in Jalisco. Local poultry farmers have been urged to reinforce the biosecurity measures on their farms and backyards and to immediately notify the health authority of any anomaly observed in their animals. The active epidemiological surveillance program is being maintained in technified production units, backyards, federally inspected slaughterhouses and municipal slaughterhouses as well as the monitoring of wild birds at national level.
