South Africa reported two outbreaks of highly pathogenic H7 bird flu in poultry east of Johannesburg, the Paris-based World Organisation for Animal Health (WOAH) said on Monday.
California's Upside Foods said on Wednesday it received regulatory approval from the U.S. Department of Agriculture for the label on its cell-cultivated chicken, making it the second company in the United States to secure that approval.
Governments should consider vaccinating birds against bird flu to avoid the virus - which has already killed hundreds of millions of birds and infected mammals worldwide - turning into a new pandemic, the head of the World Animal Health Organisation (WOAH) said.
Brazil is investigating a suspected case of avian influenza A (H5N1) in a person living in the southeastern state of Espirito Santo, where this week the first ever confirmed cases in wild birds were detected, the Health Ministry said.
Brazil is taking extra precautions to protect the world's largest poultry export industry from a highly pathogenic avian influenza virus that was this week detected among wild birds in the country after previously hitting neighboring nations.
