Avian flu: Dead sea lions, seagulls and penguins have surfaced from the Río Grande to Mar del Plata

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

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

In the laboratory of the National Health and Quality Service for Agri-Food (SENASA), the animals were diagnosed by analyzing samples of marine mammals found lifeless both in Mar del Plata and in Puerto Pirámides.

Argentina, free of pathogenic avian influenza

According to reports from the World Organization for Animal Health, Argentina has so far managed to maintain its animal health status as a “highly pathogenic avian influenza-free” country. 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 safety.

It should be noted that this disease is subject to reporting requirements in the country. So if anyone observes mass deaths or nervous, digestive or respiratory symptoms in wild or poultry birds, they can inform SENASA immediately to take appropriate action.

Therefore, veterinarians give both locals and tourists an important recommendation: it is better not to take your dogs to the beach, as there is a risk of spreading diseases.

A severe case of H5 influenza was reported in Mar del Plata, severely affecting the sea lion population. At least thirty dead specimens were recorded as a result of this eruption. The situation is worrying and requires attention to prevent the spread of this disease to other species.

Closure of beaches and other hygiene measures

In order to prevent risky situations, the authorities have decided to block pedestrian access to the colony on Escollera Sur del Puerto. One of the most important sea lion colonies in the city is located here.

In order to prevent the spread of the disease, specialists from the competent authority have taken appropriate measures when burying affected animals. To ensure biosafety in these cases, they used special machines and followed established protocols.

In this situation the doctor Diego Rodriguezteacher of National University of Mar del Plata and CONICET researchers said: “In Argentina, the mortality of seabirds and mammals has been demonstrated. In the past year there have been many cases in northern Chile and Peru. This later happened in early 2023 with the infestation of wolves on our shores. What is happening now is the end of what began in the Pacific“.

She is a marine biologist Parmigiani crystal decided that “It is the first time that we have registered cases of (sea) wolves with bird flu. There are already other diseases that could be transmitted between mammals, such as tuberculosis and toxoplasmosis. Now the bird flu virus is mutating from birds to (sea) wolves“.
