After Mizoram, cases of African Swine Fever (ASF) have been detected in Tripura's government-run breeding farm located at Devipur in Sepahijala district, top sources in the department told ANI requesting anonymity.

A team of experts from Agartala's disease investigation Centre reached the farm and formed rapid response teams to handle the situation.

"On April 7, three samples were sent to North Eastern Regional Disease Diagnostic Laboratory for testing. On April 13, last we received the PCR report that confirmed that all the samples were positive. Even the symptoms of the pigs now sheltered on the farm also indicate that the contagious disease has already entered the farm. Another report that was supposed to come from Bhopal's National Disease Diagnostic institute is yet to reach Tripura," a senior official in the Animal Husbandry Department run disease investigation laboratory said.

In the first phase, 8 feet by 8 feet graves had been dug up to bury the infected pigs after mass execution.

"Initially pigs available within the one-kilometre radius of the farm will be executed and buried to contain the spread of the disease. We are trying to confine the disease within the farm and its peripheries so that the virus does not spread across the state," said the sources.

"We have formed two task forces comprising ten people in each of the groups. The teams will be led by a veterinary officer and they will directly report to the panel of nodal officers. In charge of the Disease Investigation laboratory Dr Mrinal Dutta and SDM Bishalgarh have been included in the team of nodal officers," the source added.

"All the further proceedings can only be carried out once the official letter reaches the state government," he added.

According to officials, a total of 63 mature pigs died due to unknown reasons which raised an alarm. Before the outbreak, there were 265 mature pigs and 185 piglets in the pig shed of the farm.
