Indian officials say four chickens have tested positive for the H5 bird flu virus in western India, but it was unclear whether they had the deadly H5N1 strain.
The outbreak is in the state of Maharashtra, the scene of India's first outbreak of bird flu last month.
Officials say four villages in Jalgaon district in the northern part of the state were affected by the latest outbreak. Jalgaon is one district away from Nandurbar, where India reported the deadly H5N1 strain of bird flu last month.
Hundreds of thousands of chickens were destroyed in the town of Navapur and neighboring areas after that outbreak, and last week authorities said they had contained the virus there.
Officials say chickens in the Jalgaon area will also be culled.
