Brazil hopes to be officially free of bird flu in 28 days
Sao Paulo: Brazil began a 28-day bird flu observation period on Thursday which it hopes will show the country's chicken farms are free of the disease after local authorities said a farm where its first outbreak was detected had been fully disinfected. The outbreak in the world's largest chicken exporter, detected in the town of Montenegro in the state of Rio Grande do Sul, triggered trade bans from multiple countries. "It is under control, we have no evidence of new notifications," said Rosane Collares, a director at the state's agriculture secretariat. She said authorities will remain on watch because the incubation period of the bird flu virus is two weeks and they don't want to be caught off guard. The report from state authorities late on Wednesday that the farm was cleared means that if no other cases of bird flu are detected on Brazilian commercial chicken farms over the next 28 days, the country may be considered free of the disease. The count starts on Thursday, authorities said. "We need to ensure that the 28 days of observation occur without new outbreaks," Agriculture Minister Carlos Favaro said after a meeting with Rio Grande do Sul Governor Eduardo Leite this week. "We are reinforcing actions to ensure that everything is perfectly safe," he said. Eleven active investigations into potential bird flu cases in Brazil are ongoing, including two on commercial chicken farms in Santa Catarina and Tocantins states. On Wednesday, Tocantins state authorities ruled out an outbreak of bird flu in the farm where the investigation was being conducted, citing preliminary test results. However, the federal government is conducting additional tests, according to the agriculture ministry's website. Wagner Yanaguizawa, an analyst at Rabobank, said the next few days will be decisive in determining whether the outbreak has been contained. "After 28 days, if there are no new cases from then on, Brazil can declare itself free of the disease," he said, adding that it will then be up to the importers to lift existing trade bans. "But then trade flows will most likely return to normal," Yanaguizawa said.

Genetic test suggests Brazil's bird flu cases in farm and zoo share same strain
PORTO ALEGRE, Brazil, May 20 (Reuters) - The results of genetic tests suggested that Brazil's first outbreak of bird flu on a commercial poultry farm in the state of Rio Grande do Sul shares the strain with cases in zoo animals in the same state, an official told Reuters on Tuesday. Rosane Collares, a director at the state's agriculture department, said is not yet possible to ascertain a direct relation between the two outbreaks.

Genetic test to reveal whether Brazil's bird flu case is linked to zoo deaths, World News
MONTENEGRO, Brazil — Brazilian authorities hope to determine by Tuesday (May 20) whether a confirmed outbreak of highly pathogenic avian influenza among wild birds in a zoo in the southern state of Rio Grande do Sul is connected with the country's first bird flu case on a commercial poultry farm in the same state, an official said on Monday. Rosane Collares, a director at the state's agriculture department, told Reuters that the genetic sequencing of the virus that killed around 100 waterfowl at the zoo in the town of Sapucaia do Sul would reveal if it is related to the outbreak in a commercial poultry farm in the town of Montenegro, where the H5N1 bird flu virus is already responsible for the death of 17,000 chickens, either directly from the disease or due to cautionary culling. The farm is located about 50 kilometres from the zoo. "We need to know if there is any relation or if it was an unfortunate coincidence," she said. No zoo animals were culled following confirmation that a Black-necked swan, one of the birds that died, had caught bird flu. The protocol for wild birds is different from the one guiding commercial flocks, and does not include the culling of animals that are not sick, Collares said. Collares said the animals that died all lived around one of the zoo's lakes. On Saturday, teams from Vibra Foods, a Brazilian food processor backed by Tyson Foods that runs the farm where bird flu was detected, buried waste that had first been incinerated to prevent the spread of the virus. Tyson and Vibra have not responded to several comment requests. According to Collares, health measures were taken to prevent further contamination within the zoo's perimeter, including isolation of the area and limited access for zoo workers. [[nid:718182]]
