From US Embassy Nepal: "As you may know, the Government of Nepal has confirmed an outbreak of Avian Influenza in Kakarbhitta, Jhapa in eastern Nepal. Currently, bird flu has been confirmed only in Jha district, although active surveillance is in effect in 26 other districts which border India. Culling began as soon as the outbreak was confirmed and continues in a 3km radius of the outbreak."
So no more chicken burgers! Actually the only area confirmed is extreme south east Nepal. So not too worried about this but will definitely keep an eye on situation.
