The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed the number of birds in two flocks previously reported to have been hit by highly pathogenic avian influenza (HPAI).
One of those was a commercial table egg layer flock in Merced County, confirmed on December 5, and the other was a commercial meat turkey flock in Stanislaus County, confirmed on December 4.
APHIS reported that the Merced County flock involved 793,700 hens, while the Stanislaus County flock involved 57,700 turkeys.
These are in addition to the flock of 23,100 commercial meat turkeys in Stanislaus County and a flock of 1,723,800 commercial table egg layers in Merced County that were earlier reported by APHIS.
Each of these two counties has had one other flock where the presence of HPAI was confirmed, but flock sizes have not yet been disclosed. Both of these flocks include commercial laying hens.
More HPAI in Canada
The Canadian Food Inspection Agency (CFIA) reported that three more commercial poultry flocks in British Columbia have been struck by HPAI.
The presence of HPAI was confirmed in one flock in Chilliwack on December 6. On December 8, one flock each in Abbotsford and Langley Township were affected.
Information concerning flock type or flock size was not shared by CFIA.
With these two new detections, British Columbia has now had 63 commercial flocks hit by HPAI in 2024. Of those, 47 have been in Abbotsford and 13 have been in Chilliwack.
