Avian influenza was discovered infecting a flock of 2.26 million laying hens in Arizona, prompting officials to euthanize the flock.
The positive test in Maricopa County was the second Arizona flock affected this year, following a January case in Pinal County that involved just over 300,000 hens.
For comparison, Canada’s all-time total is 14.566 million birds, 8.7 million of them in British Columbia.
