Workers are tested for avian flu case at the Agrosuper campus in Rancagua

A team from the Seremi de Salud O'Higgins carried out tests for the detection of avian influenza on more than 20 Agrosuper workers belonging to the poultry farm affected with the disease in Rancagua.

The operation was carried out on the last day, in the epidemiological context and under sanitary protocols, after the first case of avian flu detected in the private sector, which was announced this week by the Ministry of Agriculture.


The O'Higgins Health Seremi, Carolina Torres, stressed that "our role as a health authority is to guarantee the health care of workers who may have been exposed to avian influenza infection."


In this context, she reported that they will continue to monitor "remotely or in person, as required to make sure that these workers are in optimal conditions."

One of the health authority officials who participated in the operation, Rodrigo Meza, explained that the operation was carried out "on a double shift, to test both day and night, in the context of possible risks to workers."

The samples were delivered to the Regional Hospital for the respective analysis and thus be able to rule out risks or in the event that there is a positive case, take the corresponding sanitary measures to prevent the spread of the disease.:tiphat:https://cooperativa.cl/noticias/pai...n-plantel-de-agrosuper/2023-03-16/130550.html

WEDNESDAY, MARCH 22, 2023
published by daniel nanjari
Infected backyard birds were detected in the Coltauco commune, before which the region's Health Seremi tested the inhabitants near the source of infection.


After detecting backyard birds contaminated with avian influenza in the Coltauco commune, a team from the O'Higgins Health Seremia carried out tests to detect the disease on seven people who lived there.

For her part, the regional ministerial secretary of Health of the O'Higgins region, Dr. Carolina Torres Pinto, pointed out that "following the guidelines that are established in coordination with the Agricultural and Livestock Service (SAG), the work of activation of protocols of that institution and after the Health Seremía that fulfills the role of monitoring; first to evaluate the people who may have been working in the vicinity of the birds that were positive for Avian Influenza and then to identify the risks from the epidemiological point of view, to be able to follow up together with the epidemiology delegates of the network to which this corresponds population".

The health authority pointed out that the people tested came out negative for influenza, and stressed that "in this sense we are calm, but obviously doing the corresponding follow-up from the epidemiology part."

The Health Seremi called on the inhabitants of the region to remain vigilant in the face of any irregular behavior that they could detect in birds, and made a call to follow the regular channels "we must contact the telephone numbers that are enabled by the SAG so that they They can comply with the follow-ups and evaluate if the birds could be with Avian Influenza, since it is a virus that is already circulating in the region, not only on the coasts but also in some other territories of the valley "

The numbers of the Agricultural and Livestock Service that should be called to report any abnormal behavior in birds or when finding dead specimens are: +56988763248, and the call center 223451100

First case of avian influenza confirmed in Biobío industrial plant
Aton, edited by Belén Muñoz
Saturday March 25, 2023 - 12:08


The SAG activated the corresponding sanitary protocol, which implied the slaughter of the affected birds and the isolation of the area, in order to prevent the spread of the disease to other poultry farms.

The Agricultural and Livestock Service (SAG) confirmed the detection of the first case of avian influenza in an industrial plant in the Biobío region.

Consequently, the entity activated the corresponding sanitary protocol, which involved the slaughter of the affected birds and the isolation of the area, in order to prevent the spread of the disease to other poultry farms.

This measure was reported to the members of the Avian Influenza Regional Board, led by the Presidential Delegate Daniela Dresdner and the regional director(s) of the SAG, Roberto Ferrada.

"It is to be hoped that with the rigorously implemented Biosecurity measures and the rapid action of the SAG, the virus will not spread to more nearby farms," the statement from the poultry company ends.

In this sense, Dresdner expressed his regret by pointing out that "we received the sad news of a contagion in a farm, which sets off the alarm regarding what it could mean for the production of poultry and eggs in our region. Therefore, we We met quickly to analyze all the measures that must be taken to prevent and manage this situation, as well as those that could arise in the future."

The authority also emphasized the importance of taking precautions and immediately notifying the SAG in case of detecting strange behavior in wild, domestic birds or even marine animals. In the case of productive farms, biosecurity measures must be taken to protect the birds and avoid any contact with wild birds.

On the other hand, the regional director(s) of the SAG, Roberto Ferrada, reported that the finding was produced thanks to the complaint made by the owner of the facility located in Florida, due to an increase in the mortality of laying birds.

In addition, Ferrada highlighted that the SAG has been working closely with the private sector since the global alert for H5N1 avian influenza, a highly pathogenic virus that arrived in the country through migratory birds from the northern hemisphere, was decreed in December last year.

This Friday, the SAG met with the representatives of the 13 poultry farms in the region to inform them about the situation and reinforce the biosecurity measures in these establishments.

Meanwhile, from the Avícola Chequén Spa company they stressed that in the Chequén sector of Florida there are 2 poultry, and that theirs would not be involved.

Through a statement, the company indicated that it was one of the poultry companies in the area, owned by Tomás Crovetto and family, (Ongolmo parent company, Concepción), while the second was founded by Carlos Crovetto - Tomás's brother and is known as Agrochequén (parent company Las Heras, Concepción)-

"The positive case of Avian Influenza was diagnosed in Agrochequén, which we are very sorry for and puts our company on alert, however in our case there have been no symptoms of the virus. It is to be hoped that with the Biosecurity measures rigorously implemented and the rapid act of the SAG, the virus does not spread to more nearby schools," he stated.

EPIDEMIOLOGICAL COMMENTS

March 29, 2023: A complaint was received from a company located in the municipality of Nogales, Valparaíso Region, reporting increased mortality in a unit of male breeding turkeys. It is indicated that the birds presented sudden death and cyanosis. The unit is located 250 meters from an artificial body of water, which on March 22 had been categorized as high risk by SAG officials. At the same time that a SAG team was preparing to respond to the complaint, a new communication was received by telephone, reporting an increase in mortality in a second epidemiological unit of the same company, located 250 meters from the first affected unit. Two separate SAG teams visited each epidemiological unit, observing signs such as depression, lack of appetite, sudden death, slight respiratory sounds and cyanosis. For this reason, samples are collected for molecular diagnosis of avian influenza in both units. At the time of attending to the complaint in the first unit, it was observed that in the 2nd divison of the male unit there was an increase in mortality of 2.8%, with 954 sick birds and 34 dead, while in the second unit investigated, the female division had an accumulated mortality of 5% and the male division 7.4%, with 4,847 sick birds and 10 dead. On the same day, the company communicated, by e-mail, the decision to stamp out the breeding turkeys of both epidemiological units based on its own laboratory analysis with positive PCR results for avian influenza, in addition to the signs and symptoms observed together with the mortality. March 30, 2023: The SAG laboratory confirms the presence of HPAI H5 in six of the samples collected in the male unit and three of the samples collected from the second epidemiological unit. As established in the current Avian Influenza Contingency Plan, a quarantine and culling resolution was carried out. The birds from both units were culled on March 30. The cleaning and disinfection process of the facilities began. A perifocal area of 3 km and a surveillance area of up to 7 km were established for epidemiological surveillance. Movement control was established and all epidemiological links with the company are being monitored. - Subtype: H5 (neuraminidase pending).

They will slaughter 400,000 chickens for avian flu in Gaiman
Forbes Digital
04 April 2023 21.00
The Minister of Production of Chubut, Leandro Cavaco, announced today that "the slaughter of the entire flock of a Gaiman poultry farm, estimated at approximately 400,000 laying hens, was ordered," upon confirmation of an outbreak of bird flu.


In dialogue with Télam, the official appreciated the commitment of the business group that "before the appearance of alleged cases, it notified Senasa (National Service for Agri-food Health and Quality) and when confirmed there is no other alternative than the sanitary vacuum."

The affected plant is the Carpat SA poultry farm, the main producer in the Chubut river valley located in Gaiman, 40 kilometers west of this capital, which works with a well-known supermarket and supplies businesses throughout Patagonia.

Order to slaughter 205,000 birds in Florida, Biobío Region, due to bird flu
Thursday, April 13, 2023 at 8:12 p.m.

The Agricultural and Livestock Service (SAG), under the Ministry of Agriculture, confirmed this Thursday a new outbreak of avian influenza, type A H5N1 of high pathogenicity, in the commune of Florida, in the Biobío Region.

Specifically, according to the entity, the event was recorded at Avícola Chequén facilities.

From the SAG it was indicated that around 205,000 birds will be slaughtered due to this outbreak.

The first case of bird flu in Chile was detected last December in the north and, since then, it has spread to various areas of the country.

Despite the fact that it is a disease that mainly affects wild birds and some species of mammals, such as sea lions, transmission to humans who have contact with sick animals or their remains is possible.

At the end of March, the Ministry of Health notified a case of a person with bird flu, a 53-year-old man who was infected in the north and developed a serious condition, although he did not infect anyone around him.

The University of Talca, in the city with the same name, closed its campus this Thursday due to possible cases of bird flu in its facilities and after finding several dead birds in its botanical garden.

Health authorities recommend not approaching dead birds and animals or behaviors suspected of being infected with avian influenza, especially in coastal areas, to prevent new infections in humans.
