Jaipur: A preliminary forensic report has indicated that the mysterious death of more than 4,800 migratory birds at the country's largest inland water saltwater lake near Jaipur was caused by botulism, a serious and fatal illness that affects the nerves, officials said on Friday.
A 70-member disaster management team is at Sambhar Lake, a key wintering area for tens of thousands of migratory birds, to dispose of the carcasses so that botulism does not spread to other birds. Also, a dozen teams from the Animal Husbandry Department are closely monitoring the situation.
Initially, it was suspected that the birds died due to avian flu but the report from a laboratory in Bhopal has ruled this out.
"Veterinary experts from Rajasthan University of Veterinary & Animal Sciences, Bikaner, have indicated that the deaths occurred due to botulism," principal secretary (forest) Sreya Guha told media.
Jaipur District Collector Jagroop Singh Yadav said another report on the heavy metal toxicity in the lake is awaited from a laboratory in Coimbatore.
Yadav said Bikaner university experts have said the birds died to botulism.
