Bird flu outbreak: 522 sea lions dead

Most of the animals died near the border with Uruguay. The bird flu has not yet affected “commercial production” in Brazil. Veterinary services attended to the first case on September 30 and since then dozens of dead sea lions have been found in the area.

The Rio Grande do Sul state government said Wednesday that the bird flu outbreak on Brazil's southern coast has killed at least 522 sea lions and sea lions.
The Secretariat of Agriculture and Livestock of Rio Grande do Sul confirmed in a text message to the AFP news agency: “Currently, 552 dead aquatic mammals have been recorded in various areas of the sea coast.".

Scientists suspect that the high mortality rate of sea lions is due to predation by infected birds, although the hypothesis that transmission occurs between "mammals that live underwater" cannot be ruled out.

Brazil free of avian flu in terms of commercial production

In the small town of Santa Victoria do Palmar alone, 164 animal deaths were recorded on Friday.
However, Brazil continues to maintain its disease-free status because “commercial production was not affected,” the government said.

Some of the bodies were found a few kilometers from the border with Uruguay, which recently reported the death of hundreds of sea lions, also due to bird flu.

"This news does not change the state or national health status and does not represent a risk for the consumption of meat and eggs."the department said in a statement.

Brazilian authorities said that "will no longer collect samples from animals of the same species that have been confirmed to be infected with the virus", limiting testing to only those different species that have recently shown symptoms.

At the beginning of October, the Ministry of Agriculture and Livestock reported the first outbreak of the disease in marine mammals on Cassino beach, in Rio Grande do Sul.

Peru, Chile and Argentina They have also reported deaths at sea because the virus causes severe muscular, neurological and respiratory symptoms.


Local people are advised not to approach suspicious animals and birds, although human infections are unusual.

Avian flu has caused pandemics worldwide and is transmitted through food, respiratory tract and secretions.
