PORTO ALEGRE (Reuters) - Brazil's Rio Grande do Sul state Agriculture Secretariat on Friday ruled out another suspected bird flu case at a commercial chicken farm in the town of Teutonia, after laboratory test results came back negative.

The farm is located in Rio Grande do Sul state, the same state where the only other commercial farm outbreak occurred.
