At least 3,800 pigs died during March and April in the northeastern state and many of them were found to be infected with PRRS.
"Barring Kolasib and Mamit, simultaneous outbreak of PRRS and swine fever occurred in six districts of Mizoram during March and April. The outbreak is over and no report of fresh infection or death of swines was reported since May," state Animal Husbandry and Veterinary secretary T Sangkunga told a press conference here.
On the issue of culling the PRRS infected swines, he said the decision was yet to be made as it would involve compensation.
