H5N1 is only deadly for humans at continiously exposure to infected birds.
As of yet H5N1 hasnt mutated to H5N1.(something) where it is sprreing from human to human as they feared had happened in Thailand with that dad and son.
Properly cooked bird is also still unharmful, as H5N1 as of yet hasnt mutated survive extreme temps.
I am not sure that the virus dies at +68C but it definatly does at +200C and chicken should be made at +225C for 90-110 minutes in an oven.
I dont know if it dies or hibernates at -18C but who wants to eat deepfrozen bird? :hmm:
Reminder:
You should always defrost frozen meat in your fridge and not on the kitchen table
