SAO PAULO, May 20 (Reuters) - A suspected case of bird flu in a farm worker in the Brazilian city of Montenegro came back negative, the health ministry of Rio Grande do Sul, the country's southernmost state, said in a statement on Tuesday.

The worker worked at the poultry grange where authorities last week identified Brazil's first bird flu case in a commercial farm, according to the statement. There have been no reports of human infections in Brazil since that outbreak.
