Avian influenza: dead sea lions, seagulls and penguins appeared from Río Grande to Mar del Plata

Senasa found positive cases of avian influenza along almost the entire Atlantic coast: Río Grande, Tierra del Fuego; Punta Bermeja, Río Negro; Necochea, Villarino and Mar del Plata, Buenos Aires and Punta Loyola, Santa Cruz.

During its investigations, the National Agri-Food Health and Quality Service (Senasa) has found positive cases along the Atlantic coast in several locations. These cases have been reported in Río Grande (Tierra del Fuego), Punta Bermeja (Río Negro), Necochea, Villarino and Mar del Plata (Buenos Aires) and Punta Loyola (Santa Cruz).

From the laboratory of the National Agri-Food Health and Quality Service (SENASA), the animals have been diagnosed by analyzing samples of marine mammals found dead in both Mar del Plata and Puerto Pirámides.

Argentina, free of pathogenic avian influenza

Argentina has managed to maintain its animal health status as a country "free of highly pathogenic avian influenza" to date, according to reports from the World Organization for Animal Health. Therefore, this means that the country has implemented effective measures to prevent and control this disease in birds, which is an important achievement in terms of animal health and food security.

It should be noted that this disease in the country requires mandatory notification, so if anyone observes mass deaths or nervous, digestive or respiratory symptoms in wild or poultry birds, they can immediately inform SENASA to take the corresponding measures.

Consequently, veterinarians make an important recommendation for both local residents and tourists: it is best not to take your dogs to the beach due to the risk of spreading diseases.

In Mar del Plata, a serious case of H5 influenza was reported that seriously affected the sea lion population. At least thirty dead specimens were recorded as a result of this outbreak. The situation is worrying and requires attention to prevent the spread of this disease among other species.

Closure of beaches and other health measures

In order to prevent risky situations, the authorities have made the decision to close access on foot to the pool located on the South Breakwater of the Port. This site is home to one of the most significant colonies of sea lions in the city.

To prevent the spread of diseases, professionals from the official agency in charge took appropriate measures when burying the affected animals. They used specialized machinery, following the established protocols to guarantee biosafety in these cases.

Given this situation, the doctor diego rodriguez, professor of the National University of Mar del Plata and CONICET researcher, expressed: "Mortalities of birds and marine mammals have been confirmed in Argentina. Last year, there were many cases in Northern Chile and Peru. This later led to the impact of wolves on our coasts in early 2023. What is happening now It is a tail of what began in the Pacific".

For her part, the marine biologist Crystal Parmigiani maintained that "It is the first time that we have recorded cases of sea lions with avian flu. There are already other diseases that could be spread between mammals such as tuberculosis and toxoplasmosis. Now, the bird flu virus is mutating and passing from birds to sea lions".
